September 10: Johns Hopkins COVID 19 Report

COVID-19 Situation Report

Webinar: Community Experiences with CommuniVax: Carrying Equity in COVID-19 Vaccination Forward in Local Areas

As the COVID-19 vaccination campaign continues, it is critical that vaccines are delivered fairly and equitably—so that everyone has access.

Join CommuniVax and the Johns Hopkins Center for Health Security for a webinar that will consider the impact of research and outreach in 4 local areas, which together represent a mix of Black and Hispanic/Latino communities in rural to urban areas. Local leaders and public health officials will hear about these communities and what they have done—and are doing—to address the challenges they are facing related to COVID-19 vaccination and equity.

EPI UPDATE The WHO COVID-19 Dashboard reports 223 million cumulative cases and 4.6 million deaths worldwide as of September 9. Global weekly incidence has held relatively steady at 4.5 million new cases per week for the past 4 weeks. Similarly, global weekly mortality has held steady at approximately 67-68,000 deaths per week over that same period.

Global Vaccination

The WHO reported 5.35 billion cumulative doses of SARS-CoV-2 vaccines administered globally as of September 6. A total of 2.02 billion individuals have received at least 1 dose, and 1.24 billion are fully vaccinated. Analysis from Our World in Data indicates that global daily vaccinations have declined sharply since September 1. Data from the most recent several days have tended to be artificially low due to reporting delays; however, the trend has persisted for more than a week. This indicates that there is an actual decline in daily vaccinations, which appears to be driven by a sharp decline in Asia*. Notably, daily vaccinations in China have decreased by more than 50% since August 29—down from 14.0 million doses per day to 6.5 million—which accounts for the majority of the change in Asia. Our World in Data estimates that there are 3.27 billion vaccinated individuals worldwide (1+ dose; 41.5% of the global population) and 2.32 billion who are fully vaccinated (29.5% of the global population). At the continent level, Oceania (40.5%) is on a trajectory to surpass the global average vaccination coverage (1+ doses), which would leave Africa (5.5%) as the only continent below the global average.

*The average doses administered may exhibit a sharp decrease for the most recent data particularly over the weekend, which indicates effects of reporting delays. In an effort to reflect the longer-term trends, the numbers reported here may not correspond to the most recent data.

Toward the end of 2020, the cumulative global case fatality ratio (CFR) appeared to be approximately 2.3%. At that time, the cumulative CFRs in Africa, Europe, and North America—as well as the global average—were all converging on that number. The CFRs in Oceania (3.0%) and South America (3.3%) were slightly higher but declining slowly, and Asia (1.6%) was slightly lower. Since that time, the trends have shifted at the continent level. South America’s CFR has remained elevated, holding relatively steady at approximately 3.0% since January 2021. Oceania’s CFR decreased slowly through March 2021 before declining much more quickly, falling from 2.9% to 1.3% since that time. Africa’s CFR increased slightly to 2.5% and held relatively steady, and Asia’s fell to a low of 1.3% in May 2021 before rising back to 1.5%. Europe and North America have both tracked closely with the global average, declining slowly in 2021 to approximately 2.0%. In terms of the rolling weekly average, CFR trends have generally decreased since the spring or early summer 2021. While Europe’s current average CFR is lower than it was in late June, it has exhibited a marked increase since early August, up from a low of 0.76% on August 1 to 1.25%. Currently, South America (2.2%) is the only continent reporting CFR greater than 2%, and Oceania (0.7%) is the only continent reporting less than 1%.

CFR varies widely at the national level, with countries ranging from well below 1% to nearly 20%**. A total of 17 countries are reporting cumulative CFRs of 0.5% or less, including Bhutan (0.12%), Laos (0.10%), and Singapore (0.08%) with less than 0.25%. On the other end of the spectrum, 14 countries are reporting cumulative CFRs greater than 4% (more than double the global average), including Mexico (7.7%), Peru (9.2%), and Yemen (18.7%) with greater than 7.5%. Over time, as the cumulative incidence and mortality increased, many countries settled into a relatively consistent cumulative CFR value. The trends were generally higher at the beginning of their respective epidemics and then declined to a steady-state value.

**Vanuatu has reported exactly 25.00% consistently since April 2021, and the actual value of its CFR is unclear.

Despite that overall trend, a number of countries’ CFRs have changed substantially in recent months. Since January 1, 2021, 13 countries have reported increases in their cumulative CFRs of greater than 1 percentage point (pp). Notably, 7 of these countries are in Africa, where many national epidemics faced major COVID-19 surges later than other parts of the world. While Taiwan is not a member of the WHO, it is reporting the largest increase in CFR since January, up from 0.9% to 5.2% (+4.3pp). Over that same period, 14 countries reported decreases in their CFRs of greater than 1pp, including Yemen, which fell from 29.0% to 18.7% (-10.3pp) since January 1. Interestingly, this group includes a relatively balanced mix of countries reporting CFRs that are higher (6) and lower (8) than the global average. The decreases in 2 of these countries—Brunei (0.44%) and Mauritius (0.29%)—brought them below the 1% CFR threshold, each cutting their respective CFRs by more than three-quarters. Australia (from 3.2% to 1.5%), Fiji (4.1% to 1.1%), and Iran (4.5% to 2.16%) also cut their respective CFRs by more than half.

UNITED STATES

The US surpassed 40 million cumulative cases on September 4:

1 case* to 10 million: 288 days

10 to 20 million: 54 days

20 to 30 million: 83 days

30 to 40 million: 165 days

*The US CDC now reports 35 cumulative cases on January 23, 2020, the first day included in the official data.

The US CDC reports 40.5 million cumulative COVID-19 cases and 652,480 deaths. Daily incidence appears to have passed a peak; however, this is likely due, at least in part, to delayed reporting over the US Labor Day holiday weekend (September 4-6). We will have a clearer picture of the longer-term trends next week, once reporting catches up from the holiday. A similar trend is evident for daily mortality as well. At more than 1,000 deaths per day, we expect the US to surpass 660,000 cumulative deaths within the next week. This threshold corresponds to 1 death for every 500 people in the US. The US surpassed 1 death per 1,000 population on December 18, 2020**.

**Changes in the frequency of state-level reporting may affect the accuracy of recently reported data, particularly over the weekend. In an effort to reflect the longer-term trends, the numbers reported here may not correspond to the most recent dates.

US Vaccination

The US has administered 378 million cumulative doses of SARS-CoV-2 vaccines, and daily vaccinations peaked at nearly 830,000 doses per day on August 29. The 5-day window during which we expect delayed reporting still includes most of the US Labor Day holiday weekend, but the trend peaked prior to the holiday, which could indicate the early stages of a longer-term downward trend*. In light of the new US vaccination mandates announced on September 9, we will closely monitor trends in daily vaccinations for any effects of the mandates.

There are 208.3 million individuals who have received at least 1 vaccine dose, equivalent to 62.7% of the entire US population. Among adults, 75.3% have received at least 1 dose, as well as 13.9 million adolescents aged 12-17 years. A total of 177.4 million individuals are fully vaccinated, which corresponds to 53.4% of the total population. Approximately 64.5% of adults are fully vaccinated, as well as 10.8 million adolescents aged 12-17 years.

*Due to delays in reporting, estimates for the average daily doses administered are less accurate for the most recent 5 days. The most current average provided here corresponds to 5 days ago.

US COVID-19 RESPONSE In a speech delivered on September 9 from the White House, US President Joe Biden laid out a 6-pronged COVID-19 pandemic action plan, including new federal vaccine requirements for about two-thirds of the nation’s federal and private workforce, in an effort to stem the surge caused by the Delta variant and jumpstart economic recovery. President Biden excoriated unvaccinated individuals, saying “our patience is running thin” and blaming them for harming fellow Americans. He also pushed back against the politicization of the pandemic, promising to use the power of the federal government to take on state elected officials who are “undermining” the implementation of vaccination requirements, mask mandates, and other preventive measures.

Under the new plan, all private sector companies employing more than 100 people will be required to mandate vaccination or conduct weekly testing, affecting about 80 million people. Workers at healthcare facilities that receive Medicare or Medicaid funding, about 17 million people, also will have to be vaccinated, extending an earlier requirement for workers at nursing homes to include facilities such as hospitals, home-health agencies, and dialysis centers. President Biden also is requiring all executive branch employees and federal contractors to be fully vaccinated, with no testing option, covering several million more workers. Additionally, employees of Head Start programs and schools run by the Department of Defense and Bureau of Indian Education, about 300,000 people, will be required to be vaccinated.

President Biden announced several other pieces of the plan, including a doubling of fines for travelers who refuse to wear masks in transit stations or on airplanes or trains. The government also is working with manufacturers and large retailers, including Walmart, Amazon, and Kroger, to lower the cost of at-home SARS-CoV-2 tests and distribute the tests to easily accessible sites such as shelters and food banks. The Department of Defense plans to send more teams into hard-hit areas, and the federal government will increase shipments of monoclonal antibody treatments and offer new support to small businesses.

Altogether, President Biden’s plan represents the government’s most aggressive steps yet to urge US residents to get vaccinated and help get the economy back on track. However, several of the new measures are expected to undergo political and legal challenges. Reactions to the announcements were mixed, with physicians praising the efforts to get more people vaccinated, some experts saying the plan could be “too little, too late,” and some politicians saying the measures overstep the government’s authority and are “unconstitutional.” Though the White House has repeatedly said the federal government does not have the authority to implement broad vaccine requirements for the general population or require a federal vaccine passport, the new measures likely will help boost the nation’s vaccination rate.

US PANDEMIC PREPAREDNESS The US government on September 3 released a US$65.3 billion plan to improve the nation’s pandemic preparedness strategy over the next 10 years, to be in a stronger position to handle infectious disease outbreaks such as SARS-CoV-2. The plan, titled “American Pandemic Preparedness: Transforming our Capabilities,” outlines 5 key areas that require urgent attention and provide opportunities, including transforming medical defenses, such as vaccines, therapeutics, and diagnostics; ensuring situation awareness regarding disease threats; strengthening public health systems both domestically and internationally; building core capabilities, including manufacturing and supply chains and regulatory strategies; and managing the mission, with a focus similar to the effort that took astronauts to the moon in the late-1960s. Officials called for an immediate outlay of at least $15 billion to “jump start” the efforts and proposed establishing a centralized “Mission Control” that would draw on US government-wide expertise. US President Joe Biden signed an executive order on January 20 directing a whole-of-government review of US national biopreparedness policies and re-establishing the National Security Council Directorate on Global Health Security and Biodefense, and this plan is a core element of a larger government strategy resulting from that review.

On September 8, the Trust for America’s Health (TFAH) released a report saying that 20 years after the attacks of September 11, 2001, the US remains unprepared for public health emergencies. The report, “2021 Ready or Not: Protecting the Public’s Health from Diseases, Disasters and Bioterrorism,” calls on federal, state, and local policy makers to prioritize health security, amid the ongoing COVID-19 pandemic, raging wildfires in the West, and recent damaging weather events in the South and Northeast. The report makes several recommendations, including calling for more investments in public health infrastructure, workforce, and data systems at all levels.

GLOBAL COVID-19 SUMMIT US President Joe Biden is expected to announce plans for a global COVID-19 summit at the UN General Assembly meetings the week of September 20 to discuss vaccine access for low- and middle-income countries (LMICs). Topics could include how to ramp up vaccine manufacturing and distribution, improve oxygen supplies to countries in need, and cooperation on research and development for COVID-19-related products. According to officials, the Biden administration is setting up talks between the President and other national leaders, but a more formal announcement is expected soon. On September 2, administration officials announced the US government plans to invest $2.7 billion to increase domestic production of SARS-CoV-2 vaccine components as part of President Biden’s pledge to make the US an “arsenal of vaccines for the world.”

Additionally, a group of US lawmakers last week launched the COVID-19 Global Vaccination Caucus to advocate for vaccine manufacturing, production, and distribution in LMICs as a means to increase vaccination rates in those countries.

COVAX FORECAST The COVAX initiative, aimed at guaranteeing global access to SARS-CoV-2 vaccines, on September 8 cut its forecast for vaccine doses available for delivery between now and the end of the year, amounting to more disappointing news for the effort already hindered by production slowdowns, regulatory delays, export bans, and vaccine hoarding by wealthier nations. COVAX said it expects to have access to a total of 1.425 billion vaccine doses by the end of 2021, a number about 25% lower than the initiative’s July forecast. About 1.2 billion of those doses will be made available to 92 low-income countries (LICs) participating in the COVAX Advance Market Commitment (AMC). COVAX’s 2021 goal of delivering 2 billion doses is now projected to be reached in the first quarter of 2022. In its first 6 months of operation, the initiative has delivered more than 240 million vaccine doses, but experts predict 11 billion doses are needed worldwide to slow the spread of the virus.

BOOSTER DOSES WHO Director-General Dr. Tedros Adhanom Ghebreyesus this week doubled down on an appeal for a moratorium on vaccine booster dose programs through the end of September, this time calling on wealthy nations to delay administering third doses to large swaths of their populations through the end of 2021 and instead divert those supplies to low- and middle-income countries (LMICs). Dr. Tedros also said he was “appalled” by a pharmaceutical industry projection that SARS-CoV-2 vaccine production could exceed 12 billion doses by the end of the year and reach 24 billion by June 2022, berating manufacturers for fulfilling bilateral contracts with wealthy nations while low-income countries (LICs) are “deprived of the tools to protect their people.” In a statement regarding the projection, which was conducted by London-based Airfinity, the International Federation of Pharmaceutical Manufacturers & Associations (IFPMA) called on governments to step up efforts to equitably redistribute doses to LMICs by sharing “a meaningful proportion of their doses in a responsible and timely way through COVAX or other efficient established mechanisms.” About 5.4 billion vaccine doses have been administered globally, but about 80% of those have gone to high- or upper-middle income countries, according to the WHO.

Additionally, 2 of the WHO’s top officials denounced wealthy nations for hoarding SARS-CoV-2 vaccines, treatments, and protective equipment, saying the inequities in distribution are “unfair,” “immoral,” and prolonging the pandemic. The Airfinity model predicts that even if the world’s wealthiest nations vaccinated all those individuals currently eligible and provided third doses to vulnerable populations, they would still have 1.2 billion doses left for redistribution this year. On September 9, Africa CDC John Nkengasong and WHO Africa Regional Director Matshidiso Moeti called on wealthy nations to forego boosters and redirect those extra doses to LICs, particularly on the African continent, which has been struggling to receive adequate supplies.

Notably, in addition to obtaining sufficient vaccine supplies, LICs will need to significantly increase their health expenditures—by almost 57%—to cover the costs of vaccinating 70% of their populations, if a 2-dose regimen costs US$35 and associated distribution cost is US$3.70 per person. These costs—according to estimates from the Vaccine Affordability Index, part of the Global Dashboard on COVID-19 Vaccine Equity supported by the UN Development Programme (UNDP), the WHO, and the University of Oxford—likely will need to be covered by further donations, grants, or loans, as LICs face negative economic consequences due to the pandemic.  

VACCINE DEVELOPMENT The COVID-19 pandemic prompted vaccine development to move at record speed, with more vaccines simultaneously being tested in clinical trials than ever before for any infectious disease. However, the development of next-generation SARS-CoV-2 vaccines is under threat, the Coalition for Epidemic Preparedness Innovations (CEPI) warned in a letter published September 7 in the journal Nature. According to Melanie Saville, CEPI’s Director of Vaccine Research and Development, most SARS-CoV-2 vaccines in use today were tested in placebo-controlled trials among unvaccinated individuals. However, as the number of vaccinated people increases, new vaccine candidates will need to be tested against existing vaccines instead of placebos. Therefore, manufacturers and governments must release doses of these “comparator vaccines” to support clinical trials testing new vaccines, particularly to see how they perform against new viral variants. But with most doses already spoken for in bilateral contracts that specifically spell out how the vaccines are to be used, current demand outpacing supply, and the possibility that a new vaccine will work better than the comparator, there is little incentive to release extra doses for studies. CEPI is working with manufacturers and governments to find workarounds to the issue, but unless a solution is found, the world will remain dependent upon the current vaccines authorized for use, even if new, more dangerous variants emerge.

DENMARK After nearly 550 days with restrictions to limit the spread of SARS-CoV-2, Denmark on September 10 lifted the last of its requirements, including no longer needing digital proof of vaccination to enter certain venues. This was the last of the restrictions, most of which have been lifted slowly since mid-August. The government stopped categorizing COVID-19 as a “socially critical disease,” attributing control of the virus to a successful vaccination rollout, strong epidemic control measures, and the efforts of the Danish people. More than 83% of eligible individuals are fully vaccinated, according to the Danish Health Authority. With fewer than 500 new COVID-19 cases reported daily and a reproduction rate less than 1, officials say they have the virus under control. However, they indicated they are prepared to reinstitute control measures if the number of COVID-19 hospitalizations begins to rise. The WHO has urged caution, warning the global situation remains critical. With large concerts already scheduled and people returning to “normal” life, the world is watching whether Denmark can remain restriction-free.

US HOSPITAL CRISIS STANDARDS OF CARE Hospitals in northern Idaho (US) this week began operating under “crisis standards of care,” allowing healthcare workers to ration care as facilities struggle to handle an influx of COVID-19 patients amid an increase in cases and staff shortages. Notably, Idaho has one of the lowest vaccination rates of any US state. The move, enacted by the Idaho Department of Health and Welfare for 10 hospitals and healthcare systems in the panhandle and north-central regions, allows hospitals to apportion certain resources, such as intensive care unit (ICU) beds, to patients they deem most likely to survive. Other patients will still receive care but might go without some life-saving medical equipment. The region is receiving federal assistance, with a 20-person team from the US Department of Defense, 150 National Guard troops, and about 200 federal contractors, but the state says the additional resources are not enough to handle the current surge.

Officials in neighboring Oregon also have warned the state is close to filling its ICU beds and activating crisis standards of care. Notably, Oregon last year said its crisis standards of care document was discriminatory, and in December 2020 replaced the document with 4 “crisis care principles,” developed with community input. The Oregon Association of Hospitals and Health Systems said the lack of crisis standards is “really troubling,” but the state’s Health Authority asked that providers apply the principles if necessary and noted that hospitals can implement their own crisis care standards and triage guidelines amid a public health emergency.

Officials in both states, as well as others including Louisiana and Texas, also are expressing concern over a rising number of child hospital admissions, as many schools around the country are opening. Pediatric ICUs typically have a smaller number of beds than adult ICUs and are filling quickly nationwide. The increase in childhood COVID-19 hospitalizations has led healthcare providers and hospital executives to implore adults to get vaccinated and use other preventive measures, such as mask wearing and physical distancing, to help protect children, especially those under age 12 who are not yet eligible for vaccination in the US.

VACCINE MANDATES Even prior to US President Joe Biden’s September 9 announcement of federal vaccine mandates, including for larger private companies, several other vaccine mandates in the US made the news over the past week. United Airlines, which announced its mandate in early August, is requiring all employees to be vaccinated by September 27 (5 weeks from the Pfizer-BioNTech vaccine receiving full FDA approval). This week, United announced that employees who receive an exemption will be placed on temporary leave while the airline implements appropriate safety precautions for unvaccinated employees. Those who receive a medical exemption will reportedly be placed on temporary medical leave, and those who receive a religious or personal beliefs exemption will be placed on unpaid personal leave. According to United Airlines officials, more than half of its employees who were unvaccinated when the mandate was announced have been vaccinated since then, an indication that the policy could be encouraging vaccination.

The Los Angeles Unified School District (California)—the United States’ second largest school district, covering nearly 650,000 students—is mandating SARS-CoV-2 vaccination for all students aged 12 years and older. The county school board voted unanimously in favor of the mandate (7-0, with 1 recusal). The school district previously mandated vaccinations for all employees, without a testing option that would allow individuals to opt out of vaccination. The student mandate will be implemented in phases, starting with students who participate in in-person extracurricular activities (eg, band, clubs, sports), who must be fully vaccinated by October 31. All other students must be fully vaccinated by December 19, and students who turn 12 must be fully vaccinated no later than 8 weeks after their 12th birthday. The school district began offering vaccinations at schools via a mobile vaccination clinic on August 30. Notably, the US FDA has issued an Emergency Use Authorization (EUA) for use of the Pfizer-BioNTech vaccine in children 12-15 years old, but none of the currently available vaccines have received full approval for this age group. The announcement was met with opposition from some parents, and anti-vaccine organizations have already indicated that they will file lawsuits that aim to overturn the policy.

SCHOOL MASK MANDATES Legal and legislative battles over mask mandates to help mitigate the spread of SARS-CoV-2 in schools continue across the US. In Florida, a Leon County judge ruled against Governor Ron DeSantis on September 8, allowing school districts to mandate mask use while the case challenging the state’s ban on mask mandates continues. Hours later, DeSantis’ administration filed a 41-page emergency motion asking the 1st District Court of Appeal to allow the executive order prohibiting mask mandates to remain in effect. Reportedly, the parents who filed the initial lawsuit filed their response Thursday evening, but it remains unclear when the appeals court will rule on the motion or the lawsuit itself. At least 13 Florida school districts have implemented mask mandates that do not give parents an option to opt out of the mandate, which violates the executive order. At a September 8 news conference, Governor DeSantis said he expects to win the case on appeal.

More school districts across the country are implementing mask mandates as COVID-19 cases due to the Delta variant surge, in some instances leading to the deaths of teachers. But most allow for medical or parental exemptions, allowing many students to opt out of the requirements—up to 30% in one Tennessee district—even amid rising numbers of COVID-19 cases among children. Advocacy groups, some physicians, and even state and local governments are advising parents how to write exemption letters or use federal disability laws to avoid mask mandates. In Kentucky, both houses of the state General Assembly have advanced bills that would abolish a statewide mask mandate in K-12 schools implemented by Governor Andy Beshear. According to a new USA TODAY/Ipsos poll, about two-thirds of those surveyed support school- or state-implemented mask mandates for teachers (65% of the general public, 64% of parents with school-aged children) and mask mandates for students (65% and 62%, respectively).

HYBRID IMMUNITY A preprint published in bioRxiv is the latest among several studies evaluating hybrid immunity to SARS-CoV-2. Hybrid immunity, which some are calling “superhuman immunity,” can exist in people previously infected with SARS-CoV-2 and who are fully vaccinated, as their immune systems can produce an extremely powerful immune response, including very high levels of antibodies with wide variant-neutralizing capability. For the bioRxiv study, which is not yet peer-reviewed, researchers created ‘polymutant’ spike proteins that resisted polyclonal antibody neutralization to a degree similar to already circulating variants of concern (VOCs). They found that 20 naturally occurring mutations in the SARS-CoV-2 spike protein are enough to confer almost complete resistance to the polyclonal neutralizing antibodies produced independently by convalescents and mRNA vaccine recipients. Notably, however, they found that plasma from previously infected individuals who later received mRNA vaccination neutralized the synthetic ‘polymutant’ as well as related but diverse sarbecoviruses, resulting in the so-called hybrid immunity. The sarbecoviruses included SARS-CoV-1, which caused the 2009 SARS pandemic, two viruses found in pangolins, and one in bats.

Another study published in the New England Journal of Medicine last month found similar results among people who had previous SARS-CoV-1 infection and were vaccinated with the Pfizer-BioNTech SARS-CoV-2 vaccine. This study examined the breadth of antibody cross-neutralization against 10 different sarbecoviruses: 7 from the SARS-CoV-2 clade and 3 from the SARS-CoV-1 clade, which overlap with the viruses included in the bioRxiv study. The individuals produced broad-spectrum antibodies capable of cross-clade neutralization of known VOCs and potentially emerging viruses. Though previous infection together with vaccination might help improve immune responses to future exposure, scientists warn that people should not intentionally expose themselves to infection with SARS-CoV-2.

REDUCED RISK OF “LONG COVID” AMONG VACCINATED Individuals who are fully vaccinated against SARS-CoV-2 appear to have a lower risk of developing post-acute sequelae of COVID-19 (PASC), so-called “long COVID,” than unvaccinated people, even when they experience breakthrough infections, according to a study published in The Lancet Infectious Diseases. Researchers examined data self-submitted by more than 1.2 million adults in the UK who use the COVID Symptom Study phone app, and only included the mRNA vaccines from Pfizer-BioNTech or Moderna and the viral vector vaccine from AstraZeneca-Oxford. Of those fully vaccinated, only 0.2% reported a breakthrough infection. Among those people who received 2 doses of vaccine, the risk of long COVID—defined as having symptoms lasting at least 4 weeks after infection—was reduced by almost half, the risk of hospitalization was reduced by 73%, and the risk of acute symptoms was reduced by 31%. While the researchers noted the study had limitations, including that the data were self-reported, they said it is “encouraging” that the overall proportion of cases who had long-lasting symptoms is reduced among fully vaccinated individuals and called for additional research to better characterize long COVID.

UNREPORTED DEATHS IN NURSING HOMES Due to delays in reporting case and mortality data, researchers suspect that nursing homes, with residents already at high risk of SARS-CoV-2 infection and illness, may have a higher burden of COVID-19 than previously reported in federal data. According to a cross-sectional study published in JAMA Network Open and involving 15,307 US nursing homes in the National Healthcare Safety Network (NHSN), researchers estimate there were more than 68,000 COVID-19 cases and 16,000 related deaths nationally that were not recorded in federal data during the early months of the pandemic, through May 24, 2020. These numbers represent 11.6% of COVID-19 cases and 14% of COVID-19 deaths among nursing home residents in 2020. Overall, a mean of 43.2% of all COVID-19 cases and 39.6% of COVID-19 deaths in nursing homes counted by state health departments went unreported in federal databases, the research suggests. Researchers and policymakers are considering that SARS-CoV-2 outbreaks in nursing homes may have been more onerous than previously believed, and a failure to accurately collect case and death data may have led to inaccurate conclusions about the role of nursing homes in COVID-19 outbreaks.

IVERMECTIN USE IN ARKANSAS JAIL A doctor at an Arkansas (US) jail is under investigation after using the drug ivermectin to treat inmates with COVID-19, reportedly without their consent and despite warnings from the US FDA to not use the drug to treat or prevent the disease outside of approved clinical trials. Several inmates at a Washington County jail said they were told the pills were antibiotics, vitamins, or steroids, not ivermectin, which is an antiparasitic primarily used in livestock. Jail physician Dr. Rob Karas and Washington County Sheriff Tim Helder both confirmed that ivermectin was prescribed to inmates, beginning late last year, but they claimed detainees consented to taking the pills. However, at least 3 inmates said they would never have taken the drug if they knew it was ivermectin, indicating they felt as though they were being experimented on. After hearing from inmates, the American Civil Liberties Union (ACLU) called for the administration of ivermectin to end immediately and said inmates are prepared to file a lawsuit to end the practice. As we previously reported, cases of ivermectin poisoning have risen over the past several weeks, as some conservative lawmakers, groups, and celebrities tout the drug, which has not been proven to work as prevention or treatment of SARS-CoV-2 infection. Even the drug's manufacturer, Merck, released a statement in February announcing that the drug was not effective in treating COVID-19 and should not be used to do so. The Arkansas case is a disturbing example of how jail and prison detainees continue to be dehumanized and exploited for medical experimentation in the US.

Taliban did not receive $80 billion of weapons

How Trump is wrong about the Taliban getting U.S. weapons

How Trump is wrong about the Taliban getting U.S. weapons

© Provided by NBC NewsHow Trump is wrong about the Taliban getting U.S. weapons

In the wake of the rapid collapse of the Afghan government this summer, the spectacle of Taliban militants’ jubilantly displaying thousands of captured trucks and dozens of aircraft given by the U.S. to the now-defunct Afghan military has been captured in countless images and videos of the aftermath of the American withdrawal.

There’s no denying that the loss of billions of dollars of military hardware to the Taliban is a bitter pill to swallow following the fall of the Afghan government, which the U.S. spent two decades trying to build up. And it’s true that some of the less sophisticated vehicles and weapons will remain in Taliban service for years to come, helping them enforce their rule, in yet another case of U.S. weapons’ ending up in the hands of hostile actors.

AdThe Delite

Netflix Cancels Another Rounds Of Great Shows

However, these abandoned weapons haven’t created some high-tech military juggernaut despite exaggerated claims to the contrary. To say so is to ignore what the U.S. actually spent money on in Afghanistan and what parts of that arsenal remain usable by the Taliban today. Mine-resistant trucks and 1980s-vintage utility helicopters don’t intrinsically pose a huge threat to neighboring countries — let alone the U.S.

Commonly bandied about is the particularly inaccurate sum of over $80 billion in U.S. weapons now said to be in the Taliban’s hands. Former President Donald Trump claimed in a speech last month that the U.S. had “left $83 billion worth of equipment behind,” while an infographic produced by the British newspapers The Times and The Sunday Times illustrating this total has been making the rounds. Retweeted by the likes of Donald Trump Jr., the tally reports that the Taliban captured 22,000 Humvees and 174 aircraft.

Unfortunately, some of these numbers are wildly off the mark and misrepresent the nature of the threat. These figures mistakenly count every dollar of U.S. military aid over its 20-year war as having gone to equipment and every piece of equipment transferred to the Afghan military during that time as being in the hands of the Taliban and functional today.

But over half of that roughly $80 billion went to ephemeral items like salaries for Afghan military personnel and contractors, uniforms, ammunition and fuel that was long ago spent, as well as infrastructure projects, operations and training costs. FactCheck.org calculated that equipment purchases since 2001 account for only about $18 billion.

Yet even that number is misleading. Much of the material was lost in combat — up to 100 vehicles per week at some points — or was retired from service. In addition, a very large share of U.S. military aid (particularly small arms) was allegedly pilfered by corrupt Afghan officials allied with the U.S. for sale on the black market.

Of course, even a fraction of the $80-odd billion total still adds up to a lot of hardware. But it’s important to remember that Washington armed the Afghan military to fight the Taliban, not other countries. That means the U.S. didn’t supply things like jet fighters, tanks or tactical ballistic and anti-aircraft missiles that could be aimed at other countries or international airliners for terrorist attacks.

Iranians likely to press advantage with fall of Kabul: Think tank

In fact, except for some artillery donated by Turkey, nearly all of the Afghan army’s heavy weapons — tanks, howitzers, multiple-rocket launchers and so forth — came not from the U.S. but are rather Soviet-era weapons left over from the Soviet-Afghan war in the 1980s.

What the U.S. did give the Afghan National Army were hundreds of armored personnel carriers and tens of thousands of trucks and mine-resistant ambush-protected vehicles, or MRAPs, designed to give passengers better odds of surviving Taliban ambushes. These vehicles are still readily usable by Taliban fighters, and they may find them effective for moving troops within Afghanistan and confronting local opposition forces — but not neighboring governments in a conventional war.

The Afghan air force, too, was entirely equipped for fighting the Taliban with slow, small planes rather than with fast jet fighters and bombers and armored attack helicopters. According to a report in July by the Special Inspector General for Afghanistan Reconstruction, the force counted 167 aircraft in flyable condition in the country, with all the helicopter types dating to the 1980s or earlier. (However, this count omits helicopters and around 20 PC-12 spy planes operated by the Special Mission Wing of the Afghan army.)

This inventory was then significantly reduced when the Taliban took over, with Afghan pilots flying around 50 to neighboring Tajikistan and Uzbekistan ahead of time. U.S. forces also “demilitarized” 73 aircraft left behind at Kabul International Airport, sabotaging them so extensively that the Taliban felt “angry and betrayed.”

The Taliban did capture some intact U.S.-built aircraft elsewhere in Afghanistan. And by cannibalizing parts and perhaps forcing U.S.-trained pilots and technicians who didn’t manage to flee the country to staff them, the Taliban will undoubtedly be able to get some U.S.-built aircraft off the ground, like the Black Hawk helicopter recorded flying over Kandahar, allegedly controlled by a former Afghan air force pilot.

But without proper maintenance and training, these aircraft will be usable only for basic transport duties and delivering unguided weapons. They mostly lack precision-guided bombs and rockets, as the Afghan air force was reported to be running out of these U.S.-supplied weapons a month before the pullout last month. And realistically, combat aircraft require highly trained crew and abundant spare parts to remain operational. For instance, even with the extensive assistance from the U.S., the Afghan air force struggled to maintain its aircraft and suffered shortages of qualified personnel.

Rather than aircraft or MRAPs, arguably the biggest international threat will come from 600,000 small arms and other infantry equipment, like night-vision goggles and body armor, some of which are now in Taliban hands. Some of these arms will disseminate through smuggling networks, potentially fueling violent conflict in neighboring Central Asian states.

The Taliban will surely sell some captured military equipment abroad, as well. But the big question remains whether the Afghan Taliban will actively foment insurgency abroad and host would-be revolutionaries, as it did with Al Qaeda. Unlike the Islamic State terrorist group, better known as ISIS, the Taliban today are at least ostensibly focused on governing Afghanistan, not global jihadism. And aiding and abetting these external terrorist organizations is what led to their overthrow by the U.S. in the first place.

It’s also a mistake to characterize these spoils as a technological windfall for China, Iran and Russia, even though they are, indeed, likely to seek to acquire some of the abandoned U.S. equipment, such as aircraft-mounted sensors and communication systems. These aren’t truly valuable secrets, however, as China, Iran and Russia have mostly developed such technologies domestically or had acquired them already during the U.S. occupation. Iran, for one, is likely to already have had access to Humvees via Shia militias in Iraq.

If America’s failed war against the Taliban teaches us anything, it’s a reminder that piles of military hardware can be rendered impotent by human factors, such as lacking the will to fight, familiarity with local culture and politics and belief in the legitimacy of one’s cause. Rather than bemoan the loss of Humvees and old helicopters, we should ponder why the U.S. failed so utterly to address the human factors that led many Afghans to lose faith in the U.S.-backed government, paving the way for the Taliban to take over their territory and arms.

Reason Pfizer vaccine has fewer side effects

Business Insider

Pfizer picked a COVID-19 vaccine dose far lower than Moderna's to minimize side effects, its top scientist says

  • Pfizer's top scientist said it chose a relatively low COVID-19 vaccine dose to minimize side effects.

  • Pfizer's vaccine has 30 micrograms of mRNA, the active ingredient. Moderna's has 100 micrograms.

  • Both vaccines produce similar side effects, according to the CDC.

  • See more stories on Insider's business page.

Pfizer's top scientist defended the dose of the active ingredient in the company's COVID-19 vaccine, which is lower than in Moderna's vaccine.

Pfizer's COVID-19 vaccine has 30 micrograms of mRNA, while Moderna's has 100 micrograms. Scientists have speculated that this could be a reason Pfizer's shot produced a lower antibody response than Moderna's in recent studies.

Philip Dormitzer, Pfizer's chief scientific officer, told the Financial Times on Wednesday that Pfizer and its codeveloper BioNTech "used the minimum dose level" to get an immune response that was stronger than catching COVID-19.

Dormitzer added that a higher dose might have risked more side effects.

"If you look at what's going on with all the COVID-19 vaccines out there, the derailer has often been adverse events that have cropped up," he said.

Pfizer's and Moderna's COVID-19 vaccines produce similar side effects, according to the Centers for Disease Control and Prevention. They can include arm pain, soreness, and redness; muscle aches; fatigue; and fever.

The CDC has said that a type of heart inflammation called myocarditis is an "extremely rare" side effect of both vaccines that resolves quickly.

There have been reports of so-called Moderna arm, an angry red rash that appears after getting Moderna's shot and goes away on its own. Insider contacted Moderna for comment but didn't immediately receive a response.

In the US, providers have given more than 214 million doses of Pfizer's shot and 147 million doses of Moderna's, according to the CDC.

Moderna's shot boosted antibodies higher than Pfizer's in some studies

A study of 1,600 Belgian health workers published as a research letter in the Journal of the American Medical Association on August 30 found that Moderna's COVID-19 vaccine produced twice as many antibodies as Pfizer's at six to 10 weeks after vaccination.

The authors said that the higher mRNA levels in Moderna's vaccine and a longer interval between doses "might explain this difference."

A study from the University of Virginia published as a research letter in JAMA on September 2 found no difference in antibody response among age groups with Moderna's vaccine but a lower antibody response in people 50 and older with Pfizer's. The researchers said that the differences could relate to the amount of mRNA in the vaccines.

The antibody response is just one aspect of the immune system, and the antibody level needed to protect against COVID-19 has not been established.

Vaccine protection also depends on whether the antibody response changes over time. For example, a recent study from Oxford University found that at four months, Pfizer's and AstraZeneca's vaccines produced similar levels of antibodies. The antibody levels from Pfizer's shot had waned, while the levels from AstraZeneca's remained the same, the researchers said.

Real-world data from Canada earlier this year found that after one dose, Pfizer's vaccine was 56% effective against symptomatic COVID-19 caused by the highly infectious Delta variant, while Moderna's was 72% effective.

Other factors could have influenced the results, including that Pfizer's vaccine had typically been given to older people, who tend to produce weaker immune responses. That study hasn't been scrutinized by experts in a peer review.

It's mRNA or nothing

'It's game over. It's mRNA or nothing:' Expert on future of vaccines

Pfizer (PFE) and its partner BioNTech (BNTX) recently got FDA full approval for the most widely-approved and sought after COVID-19 vaccine in the world, to date.

It signals an important change in how vaccines of the future could look, according to Arnaud Bernaert, formerly head of Global Health and Healthcare at the World Economic Forum.

Bernaert, now head of Health Security Solutions at Swiss-based SICPA, told Yahoo Finance, "I think it's game over. I think it's mRNA or nothing. [Other technology] takes too long."

Pfizer, BioNTech and Moderna (MRNA) are invested in the tech, with announcements of pursuits of combination flu-covid shots as well as other diseases.

The potential for mRNA was recognized early. "mRNA vaccines represent a promising alternative to conventional vaccine approaches because of their high potency, capacity for rapid development and potential for low-cost manufacture and safe administration," according to a 2018 article in Nature.

Bernaert cited these reasons as well. "If success needs to be defined as a function of the agility of a manufacturer to be able to reposition the DNA template for combating the next variant, I don't think the U.S. and Europe will do anything else but buy mRNA vaccines" moving forward, he said.

"They [mRNA] will represent 60% or 70% of the market. The other guys will die," he added.

But the pandemic also arrived after early development hurdles had been overcome for the technology. That included the method of delivery, lipid nanoparticles. And within the timeframe of getting the vaccines authorized, Moderna was first to reduce the storage temperatures needed from ultra-cold to normal freezer temperatures.

Now, the next step to unlocking their potential as a dominant technology will be global manufacturing, Bernaert said.

"I think mRNA is going to be a highly decentralized manufacturing technology," he said.

Deals happening now could be viewed as early efforts. That includes the various manufacturing and fill/finish deals that Pfizer and Moderna have penned in the past year.

Moderna has forged relationships with Catalent (CTLT), Switzerland-based Lonza, Spain-based Rovi, and France-based Recipharm for manufacturing. The company also partnered with Takeda (TAK) in Japan, Magenta in the United Arab Emirates and Tabuk in Saudi Arabia for distribution. It has partnered with Thermo Fisher (TMO), Sanofi (SNY), Baxter BioPharma and Samsung Biologics, in South Korea, for fill/finish. In addition, Moderna is working with Canada to set up a new manufacturing facility for future products. That's all on top of investing in its Massachusetts plant to expand manufacturing.

By comparison, pharma giant Pfizer has largely relied on its own sites in the U.S. and Europe, along with BioNTech's capacity, but recently signed agreements for global efforts. That includes with the Biovac Institute in South Africa and Eurofarma in Brazil for manufacturing. It has also partnered with Sanofi for fill/finish.

But further in the future, Bernaert expects mRNA use will lead to a decrease in the need for large-scale manufacturing footprints, "with 20,000-liter bioreactors a story of the past."

Bernaert pointed to California-based Nutcracker Therapeutics, as an example.The company is working on a smaller instrument that could give doctors access to locally-produced mRNA doses.

Already, mRNA companies have achieved improving stability at warmer temperatures compared to ultra-cold temperatures for the first doses. For now, however, the process is "crude," Bernaert said.

"The cold chain challenges will reduce, I think, over time. There will be lots of investments in better encapsulation mechanism, better lipid nanoparticles. It was very crude in the first place. I mean, let's call a spade a spade. The template itself and the way you grow enzymes, I think it's fairly crude."

He foresees synthetic biology DNA templates on the front end and better encapsulation mechanisms (lipids) on the back end. Brought together, it leads to a much more stable manufacturing process, Bernaert said.

Whatever the future holds, mRNA is set to dominate. "Viral vector technologies are going to become obsolete," Bernaert said.

September 3: Johns Hopkins COVID 19 Report

COVID-19 Situation Report

The COVID-19 Situation Report will not be published on Tuesday, September 7, 2021, in recognition of the Labor Day holiday in the US. The report will resume publication on Friday, September 10.

EPI UPDATE The WHO COVID-19 Dashboard reports 218.6 million cumulative cases and 4.53 million deaths worldwide as of September 3.

Global Vaccination

The WHO reported 5.29 billion cumulative doses of SARS-CoV-2 vaccines administered globally as of September 1. A total of 2.01 billion individuals have received at least 1 dose, and 1.21 billion are fully vaccinated. Analysis from Our World in Data indicates that global daily vaccinations are holding relatively steady at approximately 41 million doses per day, which is the third highest peak to date*. The global trend continues to closely follow the trend in Asia. Our World in Data estimates that there are 3.16 billion vaccinated individuals worldwide (1+ dose; 40.1% of the global population) and 2.16 billion who are fully vaccinated (27.4% of the global population). *The average doses administered may exhibit a sharp decrease for the most recent data particularly over the weekend, which indicates effects of reporting delays. In an effort to reflect the longer-term trends, the numbers reported here may not correspond to the most recent data.

UNITED STATES

The US CDC reported 39.5 million cumulative COVID-19 cases and 641,725 deaths. Daily incidence continues to increase, but the trend is tapering off toward a peak or plateau. On August 27, the US surpassed 150,000 new cases per day, and the current average of 153,245 is the highest since January 28. Daily mortality also continues to increase, and the mortality trend may be starting to taper off as well, although Florida’s new reporting scheme is impacting how we interpret the current trend (see below). The US surpassed 1,000 deaths per day on August 24, and the current average of 1,046 deaths per day is the highest since March 11*.

*Changes in the frequency of state-level reporting may affect the accuracy of recently reported data, particularly over the weekend. In an effort to reflect the longer-term trends, the numbers reported here may not correspond to the most recent dates.

The Florida Department of Health updated its COVID-19 mortality reporting process, which affects how the official state and CDC data are interpreted. Previously, like other states, Florida assigned dates to COVID-19 deaths corresponding to the date they were reported; however, Florida now assigns dates that correspond to the date of death. While reporting mortality by the date of death is technically the most accurate approach, it makes it difficult to monitor current trends. Deaths can take days or weeks to be identified, confirmed, and reported, which results in a sharp artificial decline in daily mortality over the most recent several days, even though the actual trend could be increasing. As deaths are confirmed, they will be added to the correct date of death, so the data from recent days will fill in over time. These delays mean that it will take extra time to identify changing trends, including the peak during a surge or the start of a new surge. Based on recent trends, we believe Florida is averaging more than 200 deaths per day; however its most recent report includes only 11 deaths for September 1, bringing its average down all the way down to 64. Because Florida represents approximately 20% of the average national daily mortality, its new reporting scheme is affecting how we interpret the national-level trend as well. The US average could easily be 100-150 deaths per day higher than the current reported value.

US Vaccination

The US has administered 372 million cumulative doses of SARS-CoV-2 vaccines, and daily vaccinations have leveled off over the past several days, hovering at slightly more than 800,000 doses per day since August 23*. We have not observed a marked increase in daily vaccinations since the US FDA issued full approval for the Pfizer-BioNTech vaccine. There are 205.9 million individuals who have received at least 1 dose, equivalent to 62.0% of the entire US population. Among adults, 74.5% have received at least 1 dose, as well as 13.5 million adolescents aged 12-17 years. A total of 175.0 million individuals are fully vaccinated, which corresponds to 52.7% of the total population. Approximately 63.7% of adults are fully vaccinated, as well as 10.4 million adolescents aged 12-17 years.

*Due to delays in reporting, estimates for the average daily doses administered are less accurate for the most recent 5 days. The most current average provided here corresponds to 5 days ago.

As we have covered previously, there are considerable disparities in terms of both vaccination coverage and the impact of the ongoing US surge at the state and regional levels. This week, we will look more closely at COVID-19 mortality since July 1 (ie, during the current surge) and any potential associations with state-level full vaccination coverage. It is well documented that full vaccination provides good protection against severe COVID-19 disease and death, including from the Delta variant. In this analysis, we will compare the raw increase in per capita cumulative mortality from July 1-September 1. Comparing the per capita values will allow us to more directly compare states to each other, and using the raw increase—ie, as opposed to the relative increase—we can mitigate the effects of the baseline cumulative incidence, which varies widely by state. By July 1, all states had removed eligibility restrictions and opened vaccination up to the general public. Daily vaccination progress slowed, so we can reasonably assume that coverage—or at least the relative differences in coverage—remained relatively consistent over that period.

The median state-level increase in per capita cumulative mortality over this period was 8 deaths per 100,000 population, and the mean was 11. This indicates that most states reported lower increases, while a small number of states reported much higher totals. In total, 32 states reported increases of 10 or fewer, and 12 states* reported increases of 15 or more, including 4 states with increases of more than 30: Louisiana (40), Florida (36), Arkansas (35), and Mississippi (34). Of the 12 states reporting increases of more than 15, 10 are in HHS Regions 4 (Southeast), 6 (South Central), and 7 (Central). Among the 16 states reporting increases of 5 deaths per 100k or fewer, the top 5 are all in Region 1 (Northeast)**, 4 states are in Region 3 (Midwest), and 3 are in Region 5 (Mid-Atlantic).

Among the 12 states reporting increases of 15 deaths per 100k or more, all but Florida (#21; 53.4%) are in the bottom half of states in terms of full vaccination coverage. Florida is also the only one of these states with full vaccination coverage greater than 50%. Eight (8) of these states are in the bottom 12 in terms of vaccination coverage, including #48 Wyoming (39.1%), #49 Alabama (38.6%), and #50 Mississippi (38.5%). Among the top 10 states in terms of full vaccination coverage, 6 are also in the top 10 in terms of the increased per capita mortality. Only 1 of the top 28 states in terms of vaccination coverage reported an increase in mortality greater than 10 deaths per 100k: Florida (+49).

Several states reported notably lower or higher increases in per capita mortality than would be expected based solely on their vaccination coverage. As noted above, Florida reported the second-largest increase in mortality, but it ranks #21 in terms of full vaccination coverage. While vaccination is a key tool in terms of mitigating the impact of COVID-19, it needs to be combined with non-pharmaceutical interventions (NPIs), such as physical distancing and mask use, to slow transmission, and Florida officials have exhibited an unwillingness to implement those types of measures during the current surge. Increased transmission and incidence will inevitably lead to increased mortality. New Jersey, Oregon, and Washington also rank considerably lower in terms of increased mortality than they do for vaccination coverage—18, 19, and 20 positions lower, respectively—but it is not immediately clear why these states, in particular, faced elevated COVID-19 mortality compared to their vaccination coverage.

Conversely, North and South Dakota rank much better in terms of increased COVID-19 mortality than their vaccination coverage would suggest. North Dakota is #44 in terms of vaccination coverage (41.8%), but it is #4 in terms of the increase in mortality (4 deaths/100k), a difference of 40 positions. South Dakota also ranks #4 in terms of increased mortality**, but it ranks #26 in terms of vaccination coverage (49.4%), a difference of 22 positions. Similarly, Nebraska and Ohio each rank 18 positions higher in terms of increased mortality than they do for vaccination coverage. Notably, these and other similar states—including Idaho, Michigan, Minnesota, and West Virginia—appear to still be in the early stages of their respective surges, so it is possible that we could observe larger increases in mortality as they move closer to their respective peaks. In contrast, most of the Region 1 states appear to already be peaking in terms of COVID-19 mortality, and their lower mortality during this surge suggests that higher vaccination coverage provided protection against severe disease and death at the state level.

With some notable exceptions, there appears to be an association between higher vaccination coverage and lower COVID-19 mortality during the current surge. The surge first emerged in Missouri, before moving south and east, into Arkansas, Louisiana, Mississippi, Alabama, and Florida, so it has been present there longer than in other parts of the country. The lower vaccination coverage in these states, however, appears to be contributing to elevated hospitalizations and mortality—in some instances, equal to or worse than their previous records. The timing of the geographic spread of the surge could also potentially factor into the lower mortality reported in states that are still in the early stages of their respective surges, particularly those with lower vaccination coverage. Additional analysis, including after more states pass their peaks and on case-fatality ratios over this period, could provide further insight into the association between state-level vaccination coverage and COVID-19 mortality during this surge.

*Delaware reported an overall increase of 20 deaths/100k, but this included a jump of 13 on August 1 due to a bolus of 130 newly reported deaths, most of which were previously unreported. Without this reporting anomaly, Delaware would have had an estimated increase of 7.

**Including ties; 6 states reported increases of 4 deaths per 100k, all tying for the #4 rank.

VARIANT OF INTEREST: MU In its August 31 COVID-19 Epidemiological Update, the WHO announced the addition of another SARS-CoV-2 variant to its list of variants of interest (VOIs), B.1.621 or “Mu.” The Mu variant, which also includes the descendent Pango lineage B.1.621.1, includes several mutations that show the potential for immune escape in both people previously infected with SARS-CoV-2 and those who are vaccinated; however, more research is necessary to confirm the theory. As of August 29, more than 4,500 sequences of the lineage were recorded in 39 countries. The Mu variant was first identified in Colombia in January 2021. Since then, the variant has spread worldwide, with cases reported in the UK, US, Europe, and Hong Kong. While the global prevalence of the Mu variant among sequenced cases is below 0.1% globally and declining, the variant accounts for at least 39% of cases in Colombia and 11% in Ecuador, with prevalence in both countries continuing to increase. But WHO warned that reports on the variant’s prevalence should be “interpreted with due consideration” because of variations in countries’ sequencing capacities. Mu is the fifth variant of interest named by the WHO since March 2021. In August, Public Health England (PHE) released a risk assessment for the variant, which it calls VUI-21JUL-01, highlighting that laboratory findings show it is similar to the Beta variant first detected in South Africa and raising concerns over its potential for immune escape. The WHO said it will continue to monitor and study the variant’s epidemiological evolution.

MASK-USE TRIAL A group of researchers from Stanford Medicine and Yale University this week released findings from the first randomized controlled trial (RCT) in a real-world setting designed to evaluate the effects of mask use on SARS-CoV-2 transmission. The researchers found that mask use, even when worn inconsistently in the community, can lead to a reduction in symptomatic COVID-19 cases. Additionally, relatively low-cost, targeted interventions promoting mask wearing can significantly increase the use of face coverings in rural, low-income countries, according to the results. Although the study is not yet published, the researchers have submitted the paper to the journal Science, whose editors encouraged its public release given the current public health policy relevance, as the pandemic worsens in many parts of the world.

The study included more than 340,000 adults in 600 villages in Bangladesh. In 300 villages, researchers implemented a mask distribution and promotion initiative, now called the “NORM” model, which stands for “No-cost mask distribution, Offering information, Reinforcement to wear masks, and Modeling by local leaders.” The researchers saw a 29 percentage-point increase in mask-wearing in the intervention villages (42%) versus the comparison villages (13%). Overall, the increased mask usage led to a 9% reduction in serologically confirmed symptomatic SARS-CoV-2 infection. Notably, 100 of the villages received cloth masks, resulting in a 5% reduction in symptoms, while 200 villages that received surgical masks saw a 12% reduction in symptoms. The use of surgical masks was especially effective for people aged 60 years or older, leading to a 35% reduction in symptomatic SARS-CoV-2 infections in that age group. The team plans to conduct further research evaluating how masks limit symptomatic cases, whether by reducing exposure to viral load or by preventing infections entirely. For now, the study provides a “gold standard” showing mask wearing is an effective way to limit symptomatic COVID-19, and the interventions are being rolled out in other parts of Bangladesh and in Pakistan, India, Nepal, and areas of Latin America.

LONG-TERM HEALTH EFFECTS The scientific community continues to investigate the long-term impacts of COVID-19 on individual health. Researchers from the University College of London announced earlier this week that their survey of children with positive COVID-19 diagnoses provided reassurance that post-acute sequelae of COVID-19 (PASC), or so-called “long COVID,” does not impact large numbers of adolescents. The research team conducted a survey of 11- to 17-year-olds in England who had positive SARS-CoV-2 tests between September 2020 and March 2021. The study, which is not yet peer-reviewed, suggests that 2-14% of children with a positive test reported having symptoms 15 weeks after their initial diagnosis. While the reported prevalence still presents a public health concern for children with COVID-19, it suggests that these issues may not be as prevalent among younger people as previously thought.

Research also continues into the scope of COVID-19's long-term impacts among adults. A recent article published in The Lancet describes 1-year outcomes of individuals who survived hospitalization due to COVID-19. The study included 1,276 survivors discharged from the Jin Yin-tan Hospital in Wuhan, China, between January 7 and May 29, 2020. The cohort was followed for 12 months, with follow-up visits at 6 and 12 months. The research team found that the proportion of patients with at least 1 residual symptom decreased from 68% to 49% between the 6-month and 12-month follow-up appointments. However, researchers noted a slight increase in the proportion of patients experiencing anxiety and depression symptoms between the 6-month check-in (23%) and the 12-month follow-up (26%). The findings show that while most individuals returned to good health 1 year following their hospitalization, the overall health status of the COVID-19 survivors remained lower than for those in a non-hospitalized control group.

Another study published in The Lancet Infectious Diseases analyzed the risk of PASC among vaccinated adults. The research team conducted a community-based, case-control study among UK-based adults who used the COVID Symptom Study mobile phone app. The study matched individuals who contracted SARS-CoV-2 after vaccination with individuals who contracted the virus before vaccination in an attempt to parse out differences in disease presentation. The research team found that the odds of COVID-19 symptoms persisting for 28 days or more among those who were fully vaccinated was approximately halved (OR 0.51) compared with unvaccinated controls. While this risk reduction provides additional reasons to support COVID-19 vaccination, there is still a low but present risk that vaccinated adults could develop long COVID.

There already are reports of individuals suffering long-term COVID symptoms who feel that the scientific community is leaving them behind. Understanding and minimizing the long-term impacts of COVID-19 disease is an essential part of response and recovery, and research endeavors such as the ones described above can help characterize what could be a long tail on the end of the pandemic.

US SCHOOLS As the school year begins for many in the US, COVID-19 cases among children are rising, with nearly 204,000 new cases added the week ending August 26, representing 22.4% of the total weekly reported cases. This marks the second week with child cases at the level of the winter surge of 2020-21 and a 5-fold increase from July 22 to August 26, according to the American Academy of Pediatrics (AAP). US CDC data show the number of COVID-19 cases and related emergency room visits and hospitalizations among children were 4 times higher in states with low vaccination rates than those with higher vaccination rates during the month of August. CDC Director Dr. Rochelle Walensky said last week that recently opened schools with COVID-19 outbreaks generally are not following federal guidelines for vaccination and universal masking among staff and students. In one Iowa school district where masking is optional, parents are being given the option to quarantine their children if they have a known exposure, as long as they remain symptom-free, increasing the risk of transmission among asymptomatic children. In schools already operating, some outbreaks have caused districts to return to virtual learning, including one Texas school district where 2 junior high teachers died of COVID-19 complications the same week.

The US Department of Education announced this week it has begun investigations into 5 states—Iowa, Oklahoma, South Carolina, Tennessee, and Utah—whose bans on mask mandates in schools might violate civil rights laws meant to protect students with disabilities. The department has not opened investigations in Florida, Texas, Arkansas, or Arizona because all of the bans in those states are not being enforced due to ongoing legal or other actions. On August 27, a Florida judge ruled that Governor Ron DeSantis and the Florida Department of Education had overstepped their authority when they banned mask mandates in the state’s school districts because the policy does not provide a parental opt out. Governor DeSantis’s lawyers on September 2 filed an appeal with the 1st District Court of Appeal in Tallahassee.

A new survey from the National Parent Teacher Association, conducted with support from the CDC Foundation, shows fewer parents want their children attending in-person classes. Prior to July 27, when the CDC updated its health guidance for schools in light of the highly contagious Delta variant, 58% of 1,448 parents and guardians surveyed said they wanted their children back in classrooms, but that figure dropped to 43% by August 8. The proportions were lower for Black (41%) and Hispanic (37%) parents, who expressed a preference for online learning. These results likely reflect the fact that Black and Hispanic children, as well as adults, are disproportionately impacted by COVID-19. On August 31, the CDC released updated FAQs for parents with school-aged children. 

US PRISONS & JAILS Reducing the number of people detained in US prisons and jails could have prevented millions of COVID-19 cases and hundreds of thousands of related deaths, as the overcrowded, tight quarters fuel a constant risk of outbreaks among inmates and staff, according to a study published September 2 in JAMA Network Open. Researchers from Northwestern Medicine, the Toulouse School of Economics, and the French National Centre for Scientific Research analyzed data collected in 1,605 US counties from January to November 2020 and found that an 80% reduction in the U.S. jail population—a level achievable simply by finding alternatives to jail detention for people accused of non-violent offenses—was associated with a 2% drop in the growth rate of daily COVID-19 cases. The reduction was greater in counties with large urban areas and when jail turnover was taken into account. The US jail population has a 55% weekly turnover rate, the study notes. This turnover, in addition to staff returning home to their communities daily, has contributed immensely to the overall number of COVID-19 cases in the US, according to the researchers. For comparison, the study also looked at other anticontagion policies, finding that nursing home visitation bans were associated with a 7.3% reduction in COVID-19 case growth rates, followed by school closures (4.3%), mask mandates (2.5%), prison visitation bans (1.2%), and stay-at-home orders (0.8%). Besides mass decarceration efforts, some experts are calling for mandatory SARS-CoV-2 vaccinations for staff and detainees in jails and prisons to help reduce the risk of outbreaks.

US HOSPITAL BURDEN Across the US, hospitals are straining under the volume of COVID-19 patients, and several states are nearly out of ICU beds. Alabama, Arkansas, Florida, Georgia, and Texas have less than 10% of their ICU beds available. Georgia hospitals have topped their January highs on some days, and adult ventilator use has far outpaced the previous high. A US Department of Health and Human Services (HHS) dashboard paints a grim picture, where 42 states are reporting 70% or greater use of inpatient beds, and 7 of the remaining 8 are in the 60-69% use category. In several states, including Montana and Oregon, the National Guard is assisting to help ease staffing shortages. Children’s hospitals are no exception, with many at or near capacity. The CEO of the Children’s Hospital Association wrote a letter to US President Joe Biden requesting federal help to handle the surge. Adding to the stress, about US$44 billion in federal aid from the US$178 billion Provider Relief Fund created last year and $8.5 billion allotted by the US Congress for rural medical care has not been distributed. Healthcare institutions, advocates, and lawmakers are urging the Biden administration to quickly decide how the funds will be divided and when they will be released. HHS has said a plan is being developed.

VACCINE EFFECTIVENESS AMONG HEALTHCARE WORKERS Coincident with the end of California’s (US) mask mandates in June 2021 and the rise of the SARS-CoV-2 Delta variant, the University of San Diego Health (UCSDH) workforce experienced an increase in SARS-CoV-2 infections, despite high vaccination rates. According to correspondence published in the New England Journal of Medicine (NEJM), between March 1 and July 31, 2021, 227 UCSDH healthcare workers tested positive for SARS-CoV-2 by rt-PCR, of whom 57.3% were fully vaccinated. Researchers calculated vaccine effectiveness by month, saying effectiveness exceeded 90% March through June, but fell to 65.5% in July (95% confidence interval [CI], 48.9 to 76.9). Additionally, the July attack rate among vaccinated individuals increased as time from vaccination grew, with those who were fully vaccinated later in the year (March through May; 3.7 per 1,000 persons [95% CI, 2.5 to 5.7]) showing an attack rate nearly half that of those vaccinated earlier in the year (January or February; 6.7 per 1,000 persons [95% CI, 5.9 to 7.8]). For unvaccinated workers, the attack rate was much higher (16.4 per 1,000 persons [95% CI, 11.8 to 22.9]). The authors attribute the change in vaccine effectiveness to the rise of the Delta variant and waning immunity, in addition to the end of masking requirements that likely resulted in increased community exposure.

But some experts have questioned the study’s conclusions, saying the reduction in vaccine effectiveness could be due to several additional or separate factors, including a small sample size for the July data; a single, large outbreak of 70 cases among workers in July; and an increase in close contacts due to loosened preventive measures. As more studies are published showing a possible decrease in vaccine effectiveness over time, it is important to consider behavior changes that could contribute to outcomes, even if the data are not captured in studies.

LATIN AMERICA & CARIBBEAN The Pan-American Health Organization (PAHO) has called on countries with surplus SARS-CoV-2 vaccines to urgently donate them to Latin American and Caribbean nations, where only 1 in 4 people have been fully vaccinated. While vaccination coverage in some countries such as Uruguay and Chile have exceeded 60%, rates are much lower in other countries, including Guatemala and Nicaragua. At a news conference, PAHO Director Dr. Carissa F. Etienne said that while every country in the region has begun administering vaccines, “immunizations are following the fault lines of inequality” in the region. She also announced the launch of the Regional Platform to Advance the Manufacturing of COVID-19 Vaccines and other Health Technologies in the Americas, which hopes to ease vaccine shortages within the region. During a recent virtual meeting, Dr. Etienne invited public and private manufacturers to submit proposals for transferring technologies or producing raw materials for mRNA vaccines, some of which PAHO already is in the process of reviewing.

In a related development, Pfizer and BioNTech announced a deal in late August with Brazilian pharmaceutical company Eurofarma to manufacture at least 100 million doses of the companies’ vaccine annually for distribution within the region, beginning next year. An additional 540 million doses are needed to ensure every country in the region can vaccinate 60% of the population.

INDIA Since mid-July, India has dramatically increased its SARS-CoV-2 vaccination rates in rural areas, where the majority of the population lives, with 70% of the nearly 120 million shots delivered in the past 3 weeks going to individuals in villages. That is up from about half in the beginning of May, when the country opened up vaccine eligibility to all adults. About 11% of the country’s population is fully vaccinated, and 37% have received at least one dose as of September 1, according to Our World In Data. While a boost in acceptance of vaccines in rural areas is promising news, India reported the largest single-day increase in new COVID-19 cases in 2 months on September 2, recording 47,092 cases. The densely populated Kerala state, which recently ended its biggest festival involving family and social gatherings, accounted for 70% of the new cases. The Kerala health ministry warned the public to take “adequate steps” to prevent the virus’s spread into surrounding states, and the federal government has warned that, like Kerala, the rest of India could see an increase in COVID-19 incidence as festival season gets underway this month and runs through early November.

Some parents and health experts are concerned the reopening of schools for the first time in 18 months amid an uptick in new cases could increase the risk of COVID-19 outbreaks. However, others say that without the ability to provide online schooling for poorer children, in-person learning is essential to keep kids on track. In Delhi, only older children will return to schools and strict measures are in place to help limit transmission, including vaccinated staff, limited classroom capacity, mandatory temperature checks, staggered lunch breaks, and physical distancing within classrooms. Several large Indian medical organizations are backing the resumption of in-person classes, urging governments to take a “calculated risk.” A recent serological survey conducted in 70 districts across 21 states showed 57% of 6- to 9-year-olds had antibodies to SARS-CoV-2, and 62% of 10- to 17-year-olds had antibodies, possibly boosting confidence in reopening schools. Still, some parents will be keeping their children at home for fear that a third wave could be looming.

NORTH KOREA North Korea has refused a shipment of nearly 3 million doses of China’s Sinovac SARS-CoV-2 vaccine from the COVAX facility, saying the vaccines should instead be provided to more seriously affected countries due to a limited global supply. Although the country has applied for assistance through COVAX, the government has yet to receive any doses, after the most recent development and a delay in a planned shipment of about 2 million AstraZeneca-Oxford vaccines earlier this year. Reportedly, the government rejected the AstraZeneca-Oxford vaccine over concerns of side effects. North Korea’s state media have reported incidents of breakthrough infections among vaccinated individuals and expressed overall doubt in the vaccines’ effectiveness. North Korea has reported zero confirmed COVID-19 cases to the WHO, but many health experts doubt those claims and worry that a large outbreak could overwhelm the country’s outdated healthcare infrastructure. In June, Supreme Leader Kim Jong-Un said the country’s COVID-19 situation was grave, without specifying details, and publicly chastised several high-ranking officials for failing to implement long-term preventive measures. Both the US and South Korea have discussed possibly offering humanitarian assistance to the impoverished nation, and Russia earlier this year offered to provide its Sputnik V vaccine, although it is unclear whether North Korea accepted.

Meridian CUSD 223 closes Highland Elementary because of COVID 19

Meridian CUSD 223

All,
After numerous conversations and true collaboration with the Health Department, I have accepted their strong recommendation to move Highland to an adaptive pause beginning Monday, August 30th. This means that there will be no in-person student attendance until September 13th and all Highland Elementary students will be in a remote learning environment.
While this decision pains me to make, I am confident that we did absolutely everything we could (including testing approximately 50 Kindergarten and 1st grade students on Thursday) in an attempt to ensure safety and stay open for in-person instruction.
This decision was not entered into lightly. Our current data throughout the district is alarming. The data from Highland is particularly eye-opening to say the least. We have 21 confirmed and probable COVID positive cases among our students, and our data indicate that up to 60 students have been quarantined this week. For context, we have 309 students between Kindergarten and Second Grade.
For comparison, we can look at our data compared to our neighboring communities. These are based on zip code comparison data publicly available on the Northwestern COVID dashboard.
The 7-day test positivity rate
Oregon/Mt. Morris/Chana - 7%
Byron - 7%
Rochelle - 4%
Forreston - 14%
Polo - 11%
MERIDIAN - 24%
New cases over the last 7 days per 100k people.
(This is used as a standard of measurement of COVID spread in a community. It simply takes a calculation of POSTIIVE CASES IN A GIVEN TIME FRAME / POPULATION X 100,000 to see the depth of spread.)
Oregon/Mt. Morris/Chana 88
Rochelle - 105
Byron - 123
Forreston - 278
Polo - 205
Meridian -545
HIGHLAND ELEMENTARY – 3,559 (based on current cases, may extend beyond 7 days)
HIGHLAND ELEMENTARY (If you include PROBABLE CASES) – 6,796 (based on current cases, may extend beyond 7 days)
Again, for context – our county has never gone over an 800 / 100k person weekly ratio throughout the Pandemic.
The adaptive pause will be for two weeks, and we will resume in-person instruction September 13th. I know that moving from in-person to remote instruction is terribly difficult and not ideal for student learning, family productivity, or parent's ability to work. In order to provide some consistency, all students will have consistent live meeting time with teachers.
· Kindergarten – 8:30 daily
· 1st Grade – 8:30 and 12:15
· 2nd Grade – 8:30 and 12:15
In addition, teachers will be accessible to parents throughout the school day. To ease this transition, students will practice logging on today and multiple packets of information and work will be sent home with students as we prepare for this transition. Additional scheduling information will also be provided in the packets sent home.
I would also like to publicly thank the health department for working with me for multiple days as we tried everything possible to remain open. I sincerely appreciate the patience that the Health Department provided as we tried everything possible to avoid receiving this recommendation. Please continue to put the health and wellness of our community at the forefront of your actions. Please continue to monitor for symptoms and report them to school. There is high transmission throughout our district and region, not just at Highland, and the more that we can get this under control the less likely there is further disruption to the learning environment.
There will be numerous logistical hurdles that this causes our families to jump over and through. For that, I do not have a good reply at this time other than I am sorry.
For any technological need or complications, please contact your teacher and nbelmonte@mail.meridian223.org.
If you have any questions, please feel free to reach out to me at your convenience.
Sincerely,
