The director of the Centers for Disease Control and Prevention late Thursday overruled the recommendation of the agency’s advisory panel to broaden the number of Americans who are now eligible for a third dose of the Pfizer COVID-19 vaccine.

The CDC’s Advisory Committee on Immunization Practices earlier Thursday voted to allow several groups of Americans to get a booster shot, but voted not to recommend it for adults age 18 to 64 who live or work in a place where the risk of COVID-19 is high. That would have included health care workers and other frontline employees.

But CDC Director Rochelle Walensky, MD, decided to reverse that recommendation and include the 18-to-64-year-olds in her final decision.

“As CDC Director, it is my job to recognize where our actions can have the greatest impact,” Dr. Walensky said in a statement late Thursday night, according to published reports. “At CDC, we are tasked with analyzing complex, often imperfect data to make concrete recommendations that optimize health. In a pandemic, even with uncertainty, we must take actions that we anticipate will do the greatest good.”

Dr. Walensky agreed with the rest of the advisory committee's decisions, which included recommendations that the following groups also be eligible for a booster shot:

• Adults ages 65 and up and residents of long-term care facilities
• Adults ages 50 to 64 who have an underlying medical condition that may increase their risk from a COVID infection
• Adults ages 18 to 49 who may be at increased risk from a COVID-19 infection because of an underlying medical condition, if a person feels like they need one based on a consideration of their individual benefit and risks.

About 26 million Americans are at least 6 months past the last dose of the Pfizer vaccines, making them eligible to receive a third dose.  About 13.6 million of them are over the age of 65.  Another 5.3 million are ages 50 to 64.

In making the recommendations, the committee left out healthcare workers. This was a departure from the Food and Drug Administration’s authorization which included boosters for those 65 and over, and for people 18 through 64 years of age who are at high risk for severe illness from the coronavirus, including essential workers – such as those in healthcare -- whose jobs increase their risk for infection.

This is the group Dr. Walensky added to the eligible list on her own.

Committee members “did not buy the need in occupational or institutional settings,” said William Schaffner, MD, an infectious disease specialist at Vanderbilt University in Nashville.  Dr. Schaffner sits on the ACIP workgroup that considered the evidence behind boosters. He said that he would have voted yes to offer boosters to healthcare and other essential workers.

“There was a real split in the committee,” he said.

The vote on boosters for healthcare and other high-risk workers was rejected 9 to 6.

“I think that there is ample evidence that people such as healthcare workers do not have repeated exposure in the workplace,” said Beth Bell, MD, a clinical professor at the University of Washington. “They’re using PPE as they should and they’re following the other policies within the healthcare setting. There’s lots of evidence that suggest that health care workers who become infected become infected because of exposures in the community.”

She was not alone in feeling cautious.

“I think this is an extremely slippery slope,” said Sarah Long, MD, a pediatric infectious disease specialist at Drexel University in Philadelphia, before her vote to reject boosters for healthcare and other high-risk workers.

“We might as well just say, ‘Give it to everybody 18 and over.’ We have an extremely effective vaccine. It’s like saying it’s not working, and it is working.”

The committee saw data showing that all of the vaccines remain highly protective against hospitalization and death for all age groups, though protection against getting sick with COVID has waned slightly over time and with the dominance of the more contagious Delta variant. Those at highest risk for a severe breakthrough infection — those that cause hospitalization or death — are older adults.
 

How much will the U.S. benefit from boosters?

Some felt squeamish about broadly recommending boosters at all.

“We have too much hope on the line with these boosters,” said James Loehr, MD, who is a family physician in Ithaca, N.Y. Dr. Loehr said he felt the goal of giving boosters in the United States should be to decrease hospitalizations, and he felt they would, but that the impact would likely be smaller than appreciated.

Based on his calculations of the benefits of boosters for each age group, Dr. Loehr said if boosters were given to all 13 million seniors previously vaccinated with the Pfizer vaccine, we might prevent 200 hospitalizations a day, “which would be a lot,” he noted. But, he said, “considering that we have 10,000 hospitalizations a day now, it’s probably not that much.”

Others agreed.

“I really think this is a solution looking for a problem,” said Jason Goldman, MD, an associate professor at Florida Atlantic University who was representing the American College of Physicians. “You know, I don’t think it’s going to address the issue of the pandemic. I really think it’s just going to create more confusion on the provider from the position of implementation, and I really think it’s going really far afield of the data.”

ACIP Chair Grace Lee, MD, a pediatric infectious disease specialist at Stanford, said she had cared for children who had died of COVID.

“I can tell you that their family members really wished they had extra protection for their kids, because they weren’t symptomatic. Nobody else was sick at home,” she said.

Dr. Lee said for her, access was paramount, and she was in favor of expanding access to boosters for as many people as possible.
 

Next steps

People who were initially vaccinated with either Moderna or Johnson & Johnson vaccines are excluded from booster recommendations, something many on the committee were uncomfortable with.

The FDA is still considering Moderna’s application to market booster doses. Johnson & Johnson hasn’t yet applied to the FDA for permission to offer second doses in the United States.

While the ACIP’s recommendations are important, in this case, they may not have a huge practical effect, said Schaffner. The CDC has already approved third shots for people who are immunocompromised, and no proof of a medical condition is required to get one.

More than 2 million people have already gotten a third dose, he noted, and not all of them are immunocompromised.

“They have heard the president say that, you know, everybody should get a booster, and they’ve taken that at face value,” he said.

The U.S. Food and Drug Administration (FDA) late Sept. 22 granted emergency use authorization (EUA) for a third dose of the Pfizer COVID-19 vaccine for those over the age of 65 and a wide swath of Americans at higher risk for infection.

The agency’s move comes as a Centers for Disease Control and Prevention (CDC) panel ended the first day of a 2-day meeting. That panel, the Advisory Committee on Immunization Practices (ACIP), is expected to vote Sept. 23 to instruct doctors on how to administer the boosters.

The FDA officially authorized the vaccine not only for individuals 65 and older, but also for people 18 through 64 years of age who are at high risk for severe illness from the coronavirus, including essential workers whose jobs increase their risk for infection.

“After considering the totality of the available scientific evidence and the deliberations of our advisory committee of independent, external experts, the FDA amended the EUA for the Pfizer-BioNTech COVID-19 vaccine to allow for a booster dose in certain populations such as health care workers, teachers and daycare staff, grocery workers and those in homeless shelters or prisons, among others,” Acting FDA Commissioner Janet Woodcock, MD, said in a news release.

The recommendations align with those from an FDA advisory panel Sept. 17.

The agency determined that the benefits of a booster dose outweigh the risks for people now authorized to receive it, according to the news release.
 

Other questions remain

So, how will this work? That was the main question weighing on the minds of the CDC’s ACIP during their first day of a 2-day meeting where they are expected to make recommendations on booster doses for Americans.

The panel discussed situations the FDA will still need to consider, such as what should be done for Americans who were originally vaccinated with a Moderna or Johnson and Johnson vaccine, but are not covered under the revised EUA, which is only for those people who received Pfizer’s two-dose vaccine regimen.

“That’s going to leave half of the people immunized in this age group having received the vaccine and being told that they’re at risk now for waning immunity and hospitalization unable to get a booster dose,” said committee member Sarah S. Long, MD, a professor of pediatrics at Drexel University College of Medicine in Philadelphia. “So that’s a big public health panic that we would like to avoid.”

Johnson and Johnson recently reported that second doses of its vaccine boosted its efficacy to almost 94% against COVID-19. A new study, published ahead of peer review, suggests that the efficacy of the single-dose Johnson and Johnson shot has fallen to about 78% against symptomatic infection during the Delta surge.

Moderna has applied for permission to market third doses of its vaccine in the United States, but the FDA has given no timeline on when it might make a decision. 

Doran Fink, MD, PhD, deputy director of the FDA’s Division of Vaccines and Related Products Applications, a representative advising the committee Sept. 22, said the agency was working as rapidly as possible on Moderna’s submission.

Regarding the question of whether it was OK to mix vaccines, rather than match them, Dr. Fink said there are currently not enough data available to inform that decision.

Those answers are coming, though. John Beigel, MD, associate director of clinical research at the National Institute of Allergy and Infectious Diseases, revealed that the federal government has a study underway to see what happens when the vaccines are mixed with each other. 

He said that data from the study would be available later this fall, and would certainly help physicians and other healthcare providers know whether it’s effective or safe to use them interchangeably.
 

Correlates of immunity

The ACIP left much of its schedule open Sept. 23 to discuss extra Pfizer doses and vote on how they should be used.

Pfizer had originally applied to the FDA for an amendment to its FDA approval, which would have given doctors a freer hand to prescribe third doses as they saw fit, in patients as young as 16.

But the FDA’s Vaccines and Related Biological Products Advisory Committee voted Sept. 17 against granting the amendment. The committee was particularly concerned about the lack of data in teens ages 16 and 17, who have the highest risk for a rare side effect that causes heart inflammation that requires hospital care.

Instead, they recommended — and the FDA agreed per their decision Sept. 22 — that third doses should be given to people at higher risk for severe breakthrough infections because of advanced age or because they work in an occupation that puts them at high risk for exposure. 

The CDC panel heard important presentations on new science that is helping to identify the correlates of immunity. 

The correlates of immunity are biomarkers that can be measured in blood that help doctors understand how protected a person may be against COVID-19. These markers of immunity are not yet known for the COVID-19 vaccines.

Emerging evidence shows that booster doses of the Pfizer vaccine cause front-line immune defenders — called binding antibodies — to roughly triple soon after a person gets the third shot. 

Neutralizing antibodies also jump soon after two vaccine doses, but they fall over time, which is natural. The body doesn’t need these foot soldiers to be on guard all the time, so they go away. 

The body retains its memory of how to make them, however, so they can quickly be marshaled again, if needed.

Early studies suggest that antibodies account for about two thirds of a person’s protection against COVID, while the longer-lasting T-cells and B-cells account for about one third.

After the antibody levels fall, it may take a few days to recreate this army. In the meantime, the virus can try to break in. This can cause symptoms, which can make a person feel terrible, but for the most part, vaccinated individuals don’t need hospital care and are nearly always protected from dying — even against the Delta variant.

Those most likely to be at risk for a breakthrough infection are older, because immune function wanes with age.
 

Essential workers

Essential workers, such as those who work in healthcare, may also benefit from high antibody levels, which can minimize symptoms and help them get back to work more quickly.

Helen Talbot, MD, MPH, an associate professor of medicine at Vanderbilt University Medical Center in Nashville, said that in her area staffing levels are critical right now.

“I’m actually sitting in one of the deepest red [states] with high rates of COVID. We don’t have enough health care workers currently to take care of the unvaccinated,” she said. 

“When we have beds, we are often missing staff, and so the idea of vaccinating health care workers is to be a little bit different than our idea of using vaccines in the general population,” Dr. Talbot said.

Oliver Brooks, MD, chief medical officer of the Watts Healthcare Corporation in Los Angeles, said he was in favor of making a public statement about the temporary nature of the potential recommendations Sept. 23, because they probably won’t cover all who might need a third shot.

“We may want to go on record stating what it is that would allow us to broaden our recommendation or restrict our recommendation,” Dr. Brooks said.

The considerations of who should get an extra dose are not always straightforward.

New modeling by the Harvard TH Chan School of Public Health and the CDC to assist the government’s decisions on boosters had a surprise finding: in nursing homes, it’s more effective to vaccinate healthcare workers than it is to give booster doses to these residents. Nursing homes are at the mercy of community transmission. 

In regions with high transmission, it’s easy for a caregiver to bring the virus into a facility — so the models found that the transmission from these workers is a more effective strategy than giving third doses to the already highly vaccinated group of seniors who live in them.

The FDA officially authorized the vaccine not only for individuals 65 and older, but also for people 18 through 64 years of age who are at high risk for severe illness from the coronavirus, including essential workers whose jobs increase their risk for infection.

“After considering the totality of the available scientific evidence and the deliberations of our advisory committee of independent, external experts, the FDA amended the EUA for the Pfizer-BioNTech COVID-19 vaccine to allow for a booster dose in certain populations such as health care workers, teachers and daycare staff, grocery workers and those in homeless shelters or prisons, among others,” Acting FDA Commissioner Janet Woodcock, MD, said in a news release.

The recommendations align with those from an FDA advisory panel Sept. 17.

The agency determined that the benefits of a booster dose outweigh the risks for people now authorized to receive it, according to the news release.
 

Other questions remain

So, how will this work? That was the main question weighing on the minds of the CDC’s ACIP during their first day of a 2-day meeting where they are expected to make recommendations on booster doses for Americans.

The panel discussed situations the FDA will still need to consider, such as what should be done for Americans who were originally vaccinated with a Moderna or Johnson and Johnson vaccine, but are not covered under the revised EUA, which is only for those people who received Pfizer’s two-dose vaccine regimen.

“That’s going to leave half of the people immunized in this age group having received the vaccine and being told that they’re at risk now for waning immunity and hospitalization unable to get a booster dose,” said committee member Sarah S. Long, MD, a professor of pediatrics at Drexel University College of Medicine in Philadelphia. “So that’s a big public health panic that we would like to avoid.”

Johnson and Johnson recently reported that second doses of its vaccine boosted its efficacy to almost 94% against COVID-19. A new study, published ahead of peer review, suggests that the efficacy of the single-dose Johnson and Johnson shot has fallen to about 78% against symptomatic infection during the Delta surge.

Moderna has applied for permission to market third doses of its vaccine in the United States, but the FDA has given no timeline on when it might make a decision. 

Doran Fink, MD, PhD, deputy director of the FDA’s Division of Vaccines and Related Products Applications, a representative advising the committee Sept. 22, said the agency was working as rapidly as possible on Moderna’s submission.

Regarding the question of whether it was OK to mix vaccines, rather than match them, Dr. Fink said there are currently not enough data available to inform that decision.

Those answers are coming, though. John Beigel, MD, associate director of clinical research at the National Institute of Allergy and Infectious Diseases, revealed that the federal government has a study underway to see what happens when the vaccines are mixed with each other. 

He said that data from the study would be available later this fall, and would certainly help physicians and other healthcare providers know whether it’s effective or safe to use them interchangeably.
 

Correlates of immunity

The ACIP left much of its schedule open Sept. 23 to discuss extra Pfizer doses and vote on how they should be used.

Pfizer had originally applied to the FDA for an amendment to its FDA approval, which would have given doctors a freer hand to prescribe third doses as they saw fit, in patients as young as 16.

But the FDA’s Vaccines and Related Biological Products Advisory Committee voted Sept. 17 against granting the amendment. The committee was particularly concerned about the lack of data in teens ages 16 and 17, who have the highest risk for a rare side effect that causes heart inflammation that requires hospital care.

Instead, they recommended — and the FDA agreed per their decision Sept. 22 — that third doses should be given to people at higher risk for severe breakthrough infections because of advanced age or because they work in an occupation that puts them at high risk for exposure. 

The CDC panel heard important presentations on new science that is helping to identify the correlates of immunity. 

The correlates of immunity are biomarkers that can be measured in blood that help doctors understand how protected a person may be against COVID-19. These markers of immunity are not yet known for the COVID-19 vaccines.

Emerging evidence shows that booster doses of the Pfizer vaccine cause front-line immune defenders — called binding antibodies — to roughly triple soon after a person gets the third shot. 

Neutralizing antibodies also jump soon after two vaccine doses, but they fall over time, which is natural. The body doesn’t need these foot soldiers to be on guard all the time, so they go away. 

The body retains its memory of how to make them, however, so they can quickly be marshaled again, if needed.

Early studies suggest that antibodies account for about two thirds of a person’s protection against COVID, while the longer-lasting T-cells and B-cells account for about one third.

After the antibody levels fall, it may take a few days to recreate this army. In the meantime, the virus can try to break in. This can cause symptoms, which can make a person feel terrible, but for the most part, vaccinated individuals don’t need hospital care and are nearly always protected from dying — even against the Delta variant.

Those most likely to be at risk for a breakthrough infection are older, because immune function wanes with age.
 

Essential workers

Essential workers, such as those who work in healthcare, may also benefit from high antibody levels, which can minimize symptoms and help them get back to work more quickly.

Helen Talbot, MD, MPH, an associate professor of medicine at Vanderbilt University Medical Center in Nashville, said that in her area staffing levels are critical right now.

“I’m actually sitting in one of the deepest red [states] with high rates of COVID. We don’t have enough health care workers currently to take care of the unvaccinated,” she said. 

“When we have beds, we are often missing staff, and so the idea of vaccinating health care workers is to be a little bit different than our idea of using vaccines in the general population,” Dr. Talbot said.

Oliver Brooks, MD, chief medical officer of the Watts Healthcare Corporation in Los Angeles, said he was in favor of making a public statement about the temporary nature of the potential recommendations Sept. 23, because they probably won’t cover all who might need a third shot.

“We may want to go on record stating what it is that would allow us to broaden our recommendation or restrict our recommendation,” Dr. Brooks said.

The considerations of who should get an extra dose are not always straightforward.

New modeling by the Harvard TH Chan School of Public Health and the CDC to assist the government’s decisions on boosters had a surprise finding: in nursing homes, it’s more effective to vaccinate healthcare workers than it is to give booster doses to these residents. Nursing homes are at the mercy of community transmission. 

In regions with high transmission, it’s easy for a caregiver to bring the virus into a facility — so the models found that the transmission from these workers is a more effective strategy than giving third doses to the already highly vaccinated group of seniors who live in them.

COVID-19 has now killed at least 675,000 Americans, a death toll that has surpassed the estimates of the number of Americans who died during the 1918 influenza pandemic, according to data collected by Johns Hopkins University.

Although the raw numbers match, epidemiologists point out that 675,000 deaths in 1918 was a much greater proportion of the population. In 1918, the U.S. population was 105 million, less than one third of what it is today.

The AIDS pandemic of the 1980s remains the deadliest of the 20th Century, claiming the lives of 700,000 Americans. But at our current pace of 2,000 COVID deaths a day, we could quickly eclipse that death toll, too.

Even though the 1918 epidemic is often called the “Spanish Flu,” there is no universal consensus regarding where the virus originated, according to the Centers for Disease Control and Prevention.

Still, the almost incomprehensible loss harkens back to a time when medicine and technology were far less advanced than they are today.

In 1918, the United States didn’t have access to a vaccine, or near real-time tools to trace the spread and communicate the threat.

In some ways, the United States has failed to learn from the mistakes of the past.

There are many similarities between the two pandemics. In the spring of 1918, when the first wave of influenza hit, the United States and its allies were nearing victory in Europe in World War I. Just this summer the United States has ended its longest war, the conflict in Afghanistan, as COVID cases surge.

In both pandemics, hospitals and funeral homes were overrun and makeshift clinics were opened where space was available. Mask mandates were installed; schools, churches, and theaters closed; and social distancing was encouraged.

As is the case today, different jurisdictions took different steps to fight the pandemic and some were more successful than others.

According to History.com, in 1918, Philadelphia’s mayor said a popular annual parade could be held, and an estimated 200,000 people attended. In less than 2 weeks, more than 1,000 local residents were dead. But in St. Louis, public gatherings were banned, schools and theaters closed, and the death toll there was one eighth of Philadelphia’s.

Just as in 1918, America has at times continued to fan the flames of the epidemic by relaxing restrictions too quickly and relying on unproven treatments. Poor communication allowed younger people to feel that they wouldn’t necessarily face the worst consequences of the virus, contributing to a false sense of security in the age group that was fueling the spread.

“A lot of the mistakes that we definitely fell into in 1918, we hoped we wouldn’t fall into in 2020,” epidemiologist Stephen Kissler, PhD, of the Harvard T.H. Chan School of Public Health, told CNN. “We did.”

The White House has filled in more details of its newly announced plans to blunt the impact of COVID-19 in the United States.

The emergency rule ordering large employers to require COVID-19 vaccines or weekly tests for their workers could be ready “within weeks,” officials said in a news briefing Sept. 10.

Labor Secretary Martin Walsh will oversee the Occupational Safety and Health Administration as the agency drafts what’s known as an emergency temporary standard, similar to the one that was issued a few months ago to protect health care workers during the pandemic.

The rule should be ready within weeks, said Jeff Zients, coordinator of the White House COVID-19 response team.

He said the ultimate goal of the president’s plan is to increase vaccinations as quickly as possible to keep schools open, the economy recovering, and to decrease hospitalizations and deaths from COVID.

Mr. Zients declined to set hard numbers around those goals, but other experts did.

“What we need to get to is 85% to 90% population immunity, and that’s going to be immunity both from vaccines and infections, before that really begins to have a substantial dampening effect on viral spread,” Ashish Jha, MD, dean of the Brown University School of Public Health, Providence, R.I., said on a call with reporters Sept. 9.

He said immunity needs to be that high because the Delta variant is so contagious.

Mandates are seen as the most effective way to increase immunity and do it quickly.

David Michaels, PhD, an epidemiologist and professor at George Washington University, Washington, says OSHA will have to work through a number of steps to develop the rule.

“OSHA will have to write a preamble explaining the standard, its justifications, its costs, and how it will be enforced,” says Dr. Michaels, who led OSHA for the Obama administration. After that, the rule will be reviewed by the White House. Then employers will have some time – typically 30 days – to comply.

In addition to drafting the standard, OSHA will oversee its enforcement.

Companies that refuse to follow the standard could be fined $13,600 per violation, Mr. Zients said.

Dr. Michaels said he doesn’t expect enforcement to be a big issue, and he said we’re likely to see the rule well before it is final.

“Most employers are law-abiding. When OSHA issues a standard, they try to meet whatever those requirements are, and generally that starts to happen when the rule is announced, even before it goes into effect,” he said.

The rule may face legal challenges as well. Several governors and state attorneys general, as well as the Republican National Committee, have promised lawsuits to stop the vaccine mandates.

Critics of the new mandates say they impinge on personal freedom and impose burdens on businesses.

But the president hit back at that notion Sept. 10.

“Look, I am so disappointed that, particularly some of the Republican governors, have been so cavalier with the health of these kids, so cavalier of the health of their communities,” President Biden told reporters.

“I don’t know of any scientist out there in this field who doesn’t think it makes considerable sense to do the six things I’ve suggested.”

Yet, others feel the new requirements didn’t go far enough.

“These are good steps in the right direction, but they’re not enough to get the job done,” said Leana Wen, MD, in an op-ed for The Washington Post.

Dr. Wen, an expert in public health, wondered why President Biden didn’t mandate vaccinations for plane and train travel. She was disappointed that children 12 and older weren’t required to be vaccinated, too.

“There are mandates for childhood immunizations in every state. The coronavirus vaccine should be no different,” she wrote.

Vaccines remain the cornerstone of U.S. plans to control the pandemic.

On Sept. 10, there was new research from the CDC and state health departments showing that the COVID-19 vaccines continue to be highly effective at preventing severe illness and death.

But the study also found that the vaccines became less effective in the United States after Delta became the dominant cause of infections here.

The study, which included more than 600,000 COVID-19 cases, analyzed breakthrough infections – cases where people got sick despite being fully vaccinated – in 13 jurisdictions in the United States between April 4 and July 17, 2021.

Epidemiologists compared breakthrough infections between two distinct points in time: Before and after the period when the Delta variant began causing most infections.

From April 4 to June 19, fully vaccinated people made up just 5% of cases, 7% of hospitalizations, and 8% of deaths. From June 20 to July 17, 18% of cases, 14% of hospitalizations, and 16% of deaths occurred in fully vaccinated people.

“After the week of June 20, 2021, when the SARS-CoV-2 Delta variant became predominant, the percentage of fully vaccinated persons among cases increased more than expected,” the study authors wrote.

Even after Delta swept the United States, fully vaccinated people were 5 times less likely to get a COVID-19 infection and more than 10 times less likely to be hospitalized or die from one.

“As we have shown in study after study, vaccination works,” CDC Director Rochelle Walensky, MD, said during the White House news briefing.

“We have the scientific tools we need to turn the corner on this pandemic. Vaccination works and will protect us from the severe complications of COVID-19,” she said.

President Joe Biden has announced a host of new plans to rein in COVID-19’s runaway transmission in the United States, including sweeping vaccine mandates that will affect 100 million American workers, nearly two-thirds of the country’s workforce.

itsmejust/Thinkstock

“As your president, I’m announcing tonight a new plan to get more Americans vaccinated to combat those blocking public health,” he said Sept. 9.

As part of a six-part plan unveiled in a speech from the State Dining Room of the White House, President Biden said he would require vaccinations for nearly 4 million federal workers and the employees of companies that contract with the federal government.

He has also directed the Occupational Safety and Health Administration to develop a rule that will require large employers -- those with at least 100 employees -- to ensure their workers are vaccinated or tested weekly.

Nearly 17 million health care workers will face new vaccine mandates as part of the conditions of participation in the Medicare and Medicaid programs.

President Biden said the federal government will require staff at federally funded Head Start programs and schools to be vaccinated. He’s also calling on all states to mandate vaccines for teachers.

“A distinct minority of Americans, supported by a distinct minority of elected officials, are keeping us from turning the corner,” PresidentBiden said. “These pandemic politics, as I refer to them, are making people sick, causing unvaccinated people to die.”

One public health official said he was glad to see the president’s bold action.

“What I saw today was the federal government trying to use its powers to create greater safety in the American population,” said Ashish K. Jha, MD, dean of the school of public health at Brown University, Providence, R.I., in a call with reporters after the speech.

National Nurses United, the largest union of registered nurses in the United States, issued a statement in support of President Biden’s new vaccination requirements, but pushed back on his language.

“…as advocates for public health, registered nurses want to be extremely clear: There is no such thing as a pandemic of only the unvaccinated. The science of epidemiology tells us there is just one deadly, global pandemic that has not yet ended, and we are all in it together. To get out of it, we must act together. All of us,” the statement says.

A host of other professional groups, including the American Medical Association and the Association of State and Territorial Health Officials, also issued statements of support for President Biden’s plan.

But the plan was not well received by all.

“I will pursue every legal option available to the state of Georgia to stop this blatantly unlawful overreach by the Biden Administration,” said Georgia Governor Brian Kemp, a Republican, in a Tweet.

The National Council for Occupational Safety and Health called the plan “a missed opportunity” because it failed to include workplace protections for essential workers such as grocery, postal, and transit workers.

“Social distancing, improved ventilation, shift rotation, and protective equipment to reduce exposure are important components of an overall plan to reduce risk and stop the virus. These tools are missing from the new steps President Biden announced today,” said Jessica Martinez, co-executive director of the group.

In addition to the new vaccination requirements, President Biden said extra doses would be on the way for people who have already been fully vaccinated in order to protect against waning immunity, starting on Sept. 20. But he noted that those plans would be contingent on the Food and Drug Administration’s approval for third doses and the Centers for Disease Control and Prevention’s recommendation of the shots.

President Biden pledged to use the Defense Production Act to ramp up production of at-home tests, which have been selling out across the nation as the Delta variant spreads.

He also announced plans to expand access to COVID-19 testing, including offering testing for free at thousands of pharmacies nationwide and getting major retailers to sell at-home COVID-19 tests at cost.

The BinaxNow test kit, which currently retails for $23.99, will now cost about $15 for two tests at Kroger, Amazon, and Walmart, according to the White House. Food banks and community health centers will get free tests, too.

He called on states to set up COVID-19 testing programs at all schools.

Jha said that in his view, the big, game-changing news out of the president’s speech was the expansion of testing.

“Our country has failed to deploy tests in a way that can really bring this pandemic under control,” Jha said. “There are plenty of reasons, data, experience to indicate that if these were widely available, it would make a dramatic difference in reducing infection numbers across our country.”.

Dr. Jha said the private market had not worked effectively to make testing more widely available, so it was “absolutely a requirement of the federal government to step in and make testing more widely available,” he said.

President Biden also announced new economic stimulus programs, saying he’s expanding loan programs to small businesses and streamlining the loan forgiveness process.

President Biden said he’s boosting help for overburdened hospitals, doubling the number of federal surge response teams sent to hard-hit areas to reduce the strain on local health care workers. He said he would increase the pace of antibody treatments to states by 50%.

“We made so much progress during the past 7 months of this pandemic. Even so, we remain at a critical moment, a critical time,” he said. “We have the tools. Now, we just have to finish the job with truth, with science, with confidence and together as one nation.”

President Joe Biden has announced a host of new plans to rein in COVID-19’s runaway transmission in the United States, including sweeping vaccine mandates that will affect 100 million American workers, nearly two-thirds of the country’s workforce.

“As your president, I’m announcing tonight a new plan to get more Americans vaccinated to combat those blocking public health,” he said Sept. 9.

As part of a six-part plan unveiled in a speech from the State Dining Room of the White House, President Biden said he would require vaccinations for nearly 4 million federal workers and the employees of companies that contract with the federal government.

He has also directed the Occupational Safety and Health Administration to develop a rule that will require large employers -- those with at least 100 employees -- to ensure their workers are vaccinated or tested weekly.

Nearly 17 million health care workers will face new vaccine mandates as part of the conditions of participation in the Medicare and Medicaid programs.

President Biden said the federal government will require staff at federally funded Head Start programs and schools to be vaccinated. He’s also calling on all states to mandate vaccines for teachers.

“A distinct minority of Americans, supported by a distinct minority of elected officials, are keeping us from turning the corner,” PresidentBiden said. “These pandemic politics, as I refer to them, are making people sick, causing unvaccinated people to die.”

One public health official said he was glad to see the president’s bold action.

“What I saw today was the federal government trying to use its powers to create greater safety in the American population,” said Ashish K. Jha, MD, dean of the school of public health at Brown University, Providence, R.I., in a call with reporters after the speech.

National Nurses United, the largest union of registered nurses in the United States, issued a statement in support of President Biden’s new vaccination requirements, but pushed back on his language.

“…as advocates for public health, registered nurses want to be extremely clear: There is no such thing as a pandemic of only the unvaccinated.

A large, real-world test of face masks in Bangladesh shows that masks work to reduce community spread of COVID-19. It also shows that surgical masks are more effective than cloth face coverings.

OsakaWayne Studios/Moment

The study, which was published ahead of peer review, demonstrates the power of careful investigation and offers a host of lessons about mask wearing that will be important worldwide. One key finding of the study, for example, is that wearing a mask doesn’t lead people to abandon social distancing, something public health officials had feared might happen if masks gave people a false sense of security.

“What we really were able to achieve is to demonstrate that masks are effective against COVID-19, even under a rigorous and systematic evaluation that was done in the throes of the pandemic,” said Ashley Styczynski, MD, who was an infectious disease fellow at Stanford (Calif.) University when she collaborated on the study with other colleagues at Stanford, Yale, and Innovations for Poverty Action, a large research and policy nonprofit organization that currently works in 22 countries.

“And so, I think people who have been holding out on wearing masks because [they] felt like there wasn’t enough evidence for it, we’re hoping this will really help bridge that gap for them,” she said.

It included more than 600 unions – or local governmental districts in Bangladesh – and roughly 340,000 people.

Half of the districts were given cloth or surgical face masks along with continual reminders to wear them properly; the other half were tracked with no intervention. Blood tests of people who developed symptoms during the study verified their infections.

Compared to villages that didn’t mask, those in which masks of any type were worn had about 9% fewer symptomatic cases of COVID-19. The finding was statistically significant and was unlikely to have occurred by chance alone.

“Somebody could read this study and say, ‘OK, you reduced COVID-19 by 9%. Big deal.’ And what I would respond to that would be that, if anything, we think that that is a substantial underestimate,” Dr. Styczynski said.

One reason they think they underestimated the effectiveness of masks is that they tested only people who were having symptoms, so people who had only very mild or asymptomatic infections were missed.

Another reason is that, among people who had symptoms, only one-third agreed to undergo a blood test. The effect may have been bigger had participation been universal.

Local transmission may have played a role, too. Rates of COVID-19 in Bangladesh were relatively low during the study. Most infections were caused by the B.1.1.7, or Alpha, variant.

Since then, Delta has taken over. Delta is thought to be more transmissible, and some studies have suggested that people infected with Delta shed more viral particles. Masks may be more effective when more virus is circulating.

The investigators also found important differences by age and by the type of mask. Villages in which surgical masks were worn had 11% fewer COVID-19 cases than villages in which masks were not worn. In villages in which cloth masks were worn, on the other hand, infections were reduced by only 5%.

The cloth masks were substantial. Each had three layers – two layers of fabric with an outer layer of polypropylene. On testing, the filtration efficiency of the cloth masks was only about 37%, compared with 95% for the three-layer surgical masks, which were also made of polypropylene.

Masks were most effective for older individuals. People aged 50-60 years who wore surgical masks were 23% less likely to test positive for COVID, compared with their peers who didn’t wear masks. For people older than 60, the reduction in risk was greater – 35%.
 

Rigorous research

The study took place over a period of 8 weeks in each district. The interventions were rolled out in waves, with the first starting in November 2020 and the last in January 2021.

Investigators gave each household free cloth or surgical face masks and showed families a video about proper mask wearing with promotional messages from the prime minister, a head imam, and a national cricket star. They also handed out free masks.

Previous studies have shown that people aren’t always truthful about wearing masks in public. In Kenya, for example, 88% of people answering a phone survey said that they wore masks regularly, but researchers determined that only 10% of them actually did so.

Investigators in the Bangladesh study didn’t just ask people if they’d worn masks, they stationed themselves in public markets, mosques, tea stalls, and on roads that were the main entrances to the villages and took notes.

They also tested various ways to educate people and to remind them to wear masks. They found that four factors were effective at promoting the wearing of masks, and they gave them an acronym – NORM.

• N for no-cost masks.
• O for offering information through the video and local leaders.
• R for regular reminders to people by investigators who stand in public markets and offer masks or encourage anyone who wasn’t wearing one or wasn’t wearing it correctly.
• M for modeling, in which local leaders, such as imams, wear masks and remind their followers to wear them.

These four measures tripled the wearing of masks in the intervention communities, from a baseline level of 13% to 42%. People continued to wear their masks properly for about 2 weeks after the study ended, indicating that they’d gotten used to wearing them.

Dr. Styczynski said that nothing else – not text message reminders, or signs posted in public places, or local incentives – moved the needle on mask wearing.
 

Saved lives and money

The study found that the strategy was cost effective, too. Giving masks to a large population and getting people to use them costs about $10,000 per life saved from COVID, on par with the cost of deploying mosquito nets to save people from malaria, Dr. Styczynski said.

“I think that what we’ve been able to show is that this is a really important tool to be used globally, especially as countries have delays in getting access to vaccines and rolling them out,” she said.

Dr. Styczynski said masks will continue to be important even in countries such as the United States, where vaccines aren’t stopping transmission 100% and there are still large portions of the population who are unvaccinated, such as children.

“If we want to reduce COVID-19 here, it’s really important that we consider the ongoing utility of masks, in addition to vaccines, and not really thinking of them as one or the other,” she said.

The study was funded by a grant from GiveWell.org. The funder had no role in the study design, interpretation, or the decision to publish.

An independent expert panel within the Centers for Disease Control and Prevention (CDC) has studied the potential benefits and risks of the Pfizer-BioNTech COVID-19 vaccine and voted unanimously to recommend the shots for all Americans ages 16 and older.

All 14 members of the Advisory Committee on Immunization Practices (ACIP) voted ‘yes’ to recommend the vaccine for Americans ages 16 and up. The vaccine was fully approved by the U.S. Food and Drug Administration (FDA) last week.

The inoculation is still available to teens ages 12 to 15 under an emergency use authorization from the FDA.

ACIP now sends its recommendation to the CDC Director Rochelle Walensky, MD, for her sign off.

After reviewing the evidence behind the vaccine, panel member Sarah Long, MD, a professor of pediatrics at Drexel University College of Medicine, Philadelphia, said she couldn’t recall another instance where panelists had so much data on which to base their recommendation.

“This vaccine is worthy of the trust of the American people,” she said.

Doctors across the country use vaccines in line with the recommendations made by the ACIP. Their approval typically means that private and government insurers will cover the cost of the shots. In the case of the COVID-19 vaccines, the government is already picking up the tab.

Few surprises

The panel’s independent review of the vaccine’s effectiveness from nine studies held few surprises. 

They found the Pfizer vaccine prevented a COVID infection with symptoms about 90%–92% of the time, at least for the first 4 months after the second shot. Protection against hospitalization and death was even higher.

The vaccine was about 89% effective at preventing a COVID infection without symptoms, according to a pooled estimate of five studies.

The data included in the review was updated only through March 13 of this year, however, and does not reflect the impact of further waning of immunity or the impact of the Delta variant.

In making their recommendation, the panel got an update on the safety of the vaccines, which have now been used in the United States for about 9 months.

The rate of anaphylaxis has settled at around five cases for every million shots given, according to the ACIP’s review of the evidence. 

Cases of myocarditis and pericarditis were more common after getting a Pfizer-BioNTech vaccine than would be expected to happen naturally in the general population, but the risk was still very rare, and elevated primarily for men younger than age 30. 

Out of 17 million second doses of Pfizer-BioNTech vaccines in the United States, there have been 327 confirmed cases of myocarditis reported to the Vaccine Adverse Event Reporting System in people who are younger than age 30. The average hospital stay for a myocarditis cases is 1 to 2 days. 

So far, no one in the United States diagnosed with myocarditis after vaccination has died.

What’s more, the risk of myocarditis after vaccination was dwarfed by the risk of myocarditis after a COVID infection. The risk of myocarditis after a COVID infection was 6 to 34 times higher than the risk after receiving an mRNA vaccine.

About 11% of people who get the vaccine experience a serious reaction to the shot, compared with about 3% in the placebo group. Serious reactions were defined as pain; swelling or redness at the injection site that interferes with activity; needing to visit the hospital or ER for pain; tissue necrosis, or having skin slough off; high fever; vomiting that requires hydration; persistent diarrhea; severe headache;  or muscle pain/severe joint pain.

“Safe and effective”

After hearing a presentation on the state of the pandemic in the US, some panel members were struck and shaken that 38% of Americans who are eligible are still not fully vaccinated.

Pablo Sanchez, MD, a pediatrician at Nationwide Children’s Hospital in Columbus, Ohio, said, “We’re doing an abysmal job vaccinating the American people. The message has to go out that the vaccines are safe and effective.”

An independent expert panel within the Centers for Disease Control and Prevention (CDC) has studied the potential benefits and risks of the Pfizer-BioNTech COVID-19 vaccine and voted unanimously to recommend the shots for all Americans ages 16 and older.

All 14 members of the Advisory Committee on Immunization Practices (ACIP) voted ‘yes’ to recommend the vaccine for Americans ages 16 and up. The vaccine was fully approved by the U.S. Food and Drug Administration (FDA) last week.

The inoculation is still available to teens ages 12 to 15 under an emergency use authorization from the FDA.

ACIP now sends its recommendation to the CDC Director Rochelle Walensky, MD, for her sign off.

After reviewing the evidence behind the vaccine, panel member Sarah Long, MD, a professor of pediatrics at Drexel University College of Medicine, Philadelphia, said she couldn’t recall another instance where panelists had so much data on which to base their recommendation.

“This vaccine is worthy of the trust of the American people,” she said.

Doctors across the country use vaccines in line with the recommendations made by the ACIP. Their approval typically means that private and government insurers will cover the cost of the shots. In the case of the COVID-19 vaccines, the government is already picking up the tab.

Over the course of the pandemic, COVID-19 has been a less serious illness for children than it has been for adults, and that continues to be true. But with the arrival of Delta, the risk for kids is rising, and that’s creating a perilous situation for hospitals across the United States that treat them. 

Roughly 1,800 kids were hospitalized with COVID-19 in the United States last week, a 500% increase in the rate of COVID-19 hospitalizations for children since early July, according to data from the Centers for Disease Control and Prevention.

Emerging data from a large study in Canada suggest that children who test positive for COVID-19 during the Delta wave may be more than twice as likely to be hospitalized as they were when previous variants were dominating transmission. The new data support what many pediatric infectious disease experts say they’ve been seeing: Younger kids with more serious symptoms.

That may sound concerning, but keep in mind that the overall risk of hospitalization for kids who have COVID-19 is still very low – about one child for every hundred who test positive for the virus will end up needing hospital care for their symptoms, according to current statistics maintained by the American Academy of Pediatrics.
 

‘This is different’

At Le Bonheur Children’s Hospital in Memphis, they saw Delta coming.

Since last year, every kid that comes to the emergency department at the hospital gets a screening test for COVID-19. 

In past waves, doctors usually found kids who were infected by accident – they tested positive after coming in for some other problem, a broken leg or appendicitis, said Nick Hysmith, MD, medical director of infection prevention at the hospital. But within the last few weeks, kids with fevers, sore throats, coughs, and runny noses started testing positive for COVID-19.

“We have seen our positive numbers go from, you know, close to about 8%-10% jump up to 20%, and then in recent weeks, we can get as high as 26% or 30%,” Dr. Hysmith said. “Then we started seeing kids sick enough to be admitted.”

“Over the last week, we’ve really seen an increase,” he said. As of August 16, the hospital had 24 children with COVID-19 admitted. Seven of the children were in the PICU, and two were on ventilators.

Arkansas Children’s Hospital had 23 young COVID-19 patients, 10 in intensive care, and five on ventilators, as of Friday, according to the Washington Post. At Children’s of Mississippi, the only hospital for kids in that state, 22 youth were hospitalized as of Monday, with three in intensive care as of August 16, according to the hospital. The nonprofit relief organization Samaritan’s Purse is setting up a second field hospital in the basement of Children’s to expand the hospital’s capacity.

“This is different,” Dr. Hysmith said. “What we’re seeing now is previously healthy kids coming in with symptomatic infection.”

This increased virulence is happening at a bad time. Schools around the United States are reopening for in-person classes, some for the first time in more than a year. Eight states have blocked districts from requiring masks, while many more have made them optional.

Children under 12 still have no access to a vaccine, so they are facing increased exposure to a germ that’s become more dangerous with little protection, especially in schools that have eschewed masks.
 

More than just COVID-19

Then there are the latent effects of the virus to contend with.

“We’re not only seeing more children now with acute SARS-CoV-2 in the hospital, we’re starting also to see an uptick of MISC – or Multisystem Inflammatory Syndrome in Children,” said Charlotte Hobbs, MD, a pediatric infectious disease specialist at Mississippi Children’s Hospital. “We are just beginning to [see] those cases, and we anticipate that’s going to get worse.”

Adding to COVID-19’s misery, another virus is also capitalizing on this increased mixing of kids back into the community. Respiratory syncytial virus (RSV) hospitalizes about 58,000 children under age 5 in the United States each year. The typical RSV season starts in the fall and peaks in February, along with influenza. This year, the RSV season is early, and it is ferocious.

The combination of the two infections is hitting children’s hospitals hard, and it’s layered on top of the indirect effects of the pandemic, such as the increased population of kids and teens who need mental health care in the wake of the crisis.

“It’s all these things happening at the same time,” said Mark Wietecha, CEO of the Children’s Hospital Association. “To have our hospitals this crowded in August is unusual.

And children’s hospitals are grappling with the same workforce shortages as hospitals that treat adults, while their pool of potential staff is much smaller.

“We can’t easily recruit physicians and nurses from adult hospitals in any practical way to staff a kids’ hospital,” Mr. Wietecha said.

Although pediatric doctors and nurses were trained to care for adults before they specialized, clinicians who primarily care for adults typically haven’t been taught how to care for kids.

Clinicians have fewer tools to fight COVID-19 infections in children than are available for adults. 

“There have been many studies in terms of therapies and treatments for acute SARS-CoV-2 infection in adults. We have less data and information in children, and on top of that, some of these treatments aren’t even available under an EUA [emergency use authorization] to children: For example, the monoclonal antibodies,” Dr. Hobbs said. 

Antibody treatments are being widely deployed to ease the pressure on hospitals that treat adults. But these therapies aren’t available for kids.

That means children’s hospitals could quickly become overwhelmed, especially in areas where community transmission is high, vaccination rates are low, and parents are screaming about masks.

“So we really have this constellation of events that really doesn’t favor children under the age of 12,” Dr. Hobbs said.

“Universal masking shouldn’t be a debate, because it’s the one thing, with adult vaccination, that can be done to protect this vulnerable population,” she said.  “This isn’t a political issue. It’s a public health issue. Period.”

The state of Mississippi is out of intensive care unit beds. The University of Mississippi Medical Center in Jackson – the state’s largest health system – is converting part of a parking garage into a field hospital to make more room.

“Hospitals are full from Memphis to Gulfport, Natchez to Meridian. Everything’s full,” said Alan Jones, MD, the hospital’s COVID-19 response leader, in a press briefing Aug. 11.

The state has requested the help of a federal disaster medical assistance team of physicians, nurses, respiratory therapists, pharmacists, and paramedics to staff the extra beds. The goal is to open the field hospital on Aug. 13.

Arkansas hospitals have as little as eight ICU beds left to serve a population of 3 million people. Alabama isn’t far behind.

As of Aug. 10, several large metro Atlanta hospitals were diverting patients because they were full.

Hospitals in Alabama, Florida, Tennessee, and Texas are canceling elective surgeries, as they are flooded with COVID patients.  

Florida has ordered more ventilators from the federal government. Some hospitals in that state have so many patients on high-flow medical oxygen that it is taxing the building supply lines.

“Most hospitals were not designed for this type of volume distribution in their facilities,” said Mary Mayhew, president of the Florida Hospital Association.

That’s when they can get it. Oxygen deliveries have been disrupted because of a shortage of drivers who are trained to transport it.

“Any disruption in the timing of a delivery can be hugely problematic because of the volume of oxygen they’re going through,” Ms. Mayhew said.
 

Hospitals ‘under great stress’

In a setting where most Americans now have access to safe and highly effective vaccines, hospitals in the Southeast are once again under siege from COVID-19.

Over the month of June, the number of COVID patients in Florida hospitals soared from 2,000 to 10,000. Ms. Mayhew says it took twice as long during the last surge for the state to reach those numbers. And they’re still climbing. The state had 15,000 hospitalized COVID patients as of Aug. 11.

COVID hospitalizations tripled in 3 weeks in South Carolina, said state epidemiologist Linda Bell, MD, in a news conference Aug. 11.

“These hospitals are under great stress,” says Eric Toner, MD, a senior scientist at the Johns Hopkins Center for Health Security in Baltimore

The Delta variant has swept through the unvaccinated South with such veracity that hospitals in the region are unable to keep up. Patients with non-COVID health conditions are in jeopardy too.

Lee Owens, age 56, said he was supposed to have triple bypass surgery on Aug. 12 at St. Thomas West Hospital in Nashville, Tenn. Three of the arteries around his heart are 100%, 90%, and 70% blocked. Mr. Owens said the hospital called him Aug. 10 to postpone his surgery because they’ve cut back elective procedures to just one each day because the ICU beds there are full.

“I’m okay with having to wait a few days (my family isn’t!), especially if there are people worse than me, but so much anger at the reason,” he said. “These idiots that refused health care are now taking up my slot for heart surgery. It’s really aggravating.”

Anjali Bright, a spokesperson for St. Thomas West, provided a statement to this news organization saying they are not suspending elective procedures, but they are reviewing those “requiring an inpatient stay on a case-by-case basis.”

She emphasized, though, that “we will never delay care if the patient’s status changes to ‘urgent.’ ”

“Because of how infectious this variant is, this has the potential to be so much worse than what we saw in January,” said Donald Williamson, MD, president of the Alabama Hospital Association.

Dr. Williamson said they have modeled three possible scenarios for spread in the state, which ranks dead last in the United States for vaccination, with just 35% of its population fully protected. If the Delta variant spreads as it did in the United Kingdom, Alabama could see it hospitalize up to 3,000 people. 

“That’s the best scenario,” he said.

If it sweeps through the state as it did in India, Alabama is looking at up to 4,500 patients hospitalized, a number that would require more beds and more staff to care for patients.

Then, there is what Dr. Williamson calls his “nightmare scenario.” If the entire state begins to see transmission rates as high as they’re currently seeing in coastal Mobile and Baldwin counties, that could mean up to 8,000 people in the hospital.

“If we see R-naughts of 5-8 statewide, we’re in real trouble,” he said. The R-naught is the basic rate of reproduction, and it means that each infected person would go on to infect 5-8 others. Dr. Williamson said the federal government would have to send them more staff to handle that kind of a surge.
 

‘Sense of betrayal’

Unlike the surges of last winter and spring, which sent hospitals scrambling for beds and supplies, the biggest pain point for hospitals now is staffing.

In Mississippi, where 200 patients are parked in emergency departments waiting for available and staffed ICU beds, the state is facing Delta with 2,000 fewer registered nurses than it had during its winter surge. 

Some have left because of stress and burnout. Others have taken higher-paying jobs with travel nursing companies. To stop the exodus, hospitals are offering better pay, easier schedules, and sign-on and stay-on bonuses.

Doctors say the incentives are nice, but they don’t help with the anguish and anger many feel after months of battling COVID.

“There’s a big sense of betrayal,” said Sarah Nafziger, MD, vice president of clinical support services at the University of Alabama at Birmingham Hospital. “Our staff and health care workers, in general, feel like we’ve been betrayed by the community.”

“We have a vaccine, which is the key to ending this pandemic and people just refuse to take it, and so I think we’re very frustrated. We feel that our communities have let us down by not taking advantage of the vaccine,” Dr. Nafziger said. “It’s just baffling to me and it’s broken my heart every single day.”

Dr. Nafziger said she met with several surgeons at UAB on Aug. 11 and began making decisions about which surgeries would need to be canceled the following week. “We’re talking about cancer surgery. We’re talking about heart surgery. We’re talking about things that are critical to people.”

Compounding the staffing problems, about half of hospital workers in Alabama are still unvaccinated. Dr. Williamson says they’re now starting to see these unvaccinated health care workers come down with COVID too. He says that will exacerbate their surge even further as health care workers become too sick to help care for patients and some will end up needing hospital beds themselves.

At the University of Mississippi Medical Center, 70 hospital employees and another 20 clinic employees are now being quarantined or have COVID, Dr. Jones said.

“The situation is bleak for Mississippi hospitals,” said Timothy Moore, president and CEO of the Mississippi Hospital Association. He said he doesn’t expect it to get better anytime soon.

Mississippi has more patients hospitalized now than at any other point in the pandemic, said Thomas Dobbs, MD, MPH, the state epidemiologist.

“If we look at the rapidity of this rise, it’s really kind of terrifying and awe-inspiring,” Dr. Dobbs said in a news conference Aug. 11.

Schools are just starting back, and, in many parts of the South, districts are operating under a patchwork of policies – some require masks, while others have made them voluntary. Physicians say they are bracing for what these half measures could mean for pediatric cases and community transmission.

The only sure way for people to help themselves and their hospitals and schools, experts said, is vaccination.

“State data show that in this latest COVID surge, 97% of new COVID-19 infections, 89% of hospitalizations, and 82% of deaths occur in unvaccinated residents,” Mr. Moore said.

“To relieve pressure on hospitals, we need Mississippians – even those who have previously had COVID – to get vaccinated and wear a mask in public. The Delta variant is highly contagious and we need to do all we can to stop the spread,” he said.

The state of Mississippi is out of intensive care unit beds. The University of Mississippi Medical Center in Jackson – the state’s largest health system – is converting part of a parking garage into a field hospital to make more room.

“Hospitals are full from Memphis to Gulfport, Natchez to Meridian. Everything’s full,” said Alan Jones, MD, the hospital’s COVID-19 response leader, in a press briefing Aug. 11.

The state has requested the help of a federal disaster medical assistance team of physicians, nurses, respiratory therapists, pharmacists, and paramedics to staff the extra beds. The goal is to open the field hospital on Aug. 13.

Arkansas hospitals have as little as eight ICU beds left to serve a population of 3 million people. Alabama isn’t far behind.

As of Aug. 10, several large metro Atlanta hospitals were diverting patients because they were full.

Hospitals in Alabama, Florida, Tennessee, and Texas are canceling elective surgeries, as they are flooded with COVID patients.  

Florida has ordered more ventilators from the federal government. Some hospitals in that state have so many patients on high-flow medical oxygen that it is taxing the building supply lines.

“Most hospitals were not designed for this type of volume distribution in their facilities,” said Mary Mayhew, president of the Florida Hospital Association.

That’s when they can get it. Oxygen deliveries have been disrupted because of a shortage of drivers who are trained to transport it.

“Any disruption in the timing of a delivery can be hugely problematic because of the volume of oxygen they’re going through,” Ms. Mayhew said.
 

Hospitals ‘under great stress’

In a setting where most Americans now have access to safe and highly effective vaccines, hospitals in the Southeast are once again under siege from COVID-19.

Over the month of June, the number of COVID patients in Florida hospitals soared from 2,000 to 10,000. Ms. Mayhew says it took twice as long during the last surge for the state to reach those numbers. And they’re still climbing. The state had 15,000 hospitalized COVID patients as of Aug. 11.

COVID hospitalizations tripled in 3 weeks in South Carolina, said state epidemiologist Linda Bell, MD, in a news conference Aug. 11.

“These hospitals are under great stress,” says Eric Toner, MD, a senior scientist at the Johns Hopkins Center for Health Security in Baltimore

The Delta variant has swept through the unvaccinated South with such veracity that hospitals in the region are unable to keep up. Patients with non-COVID health conditions are in jeopardy too.

Lee Owens, age 56, said he was supposed to have triple bypass surgery on Aug. 12 at St. Thomas West Hospital in Nashville, Tenn. Three of the arteries around his heart are 100%, 90%, and 70% blocked. Mr. Owens said the hospital called him Aug. 10 to postpone his surgery because they’ve cut back elective procedures to just one each day because the ICU beds there are full.

“I’m okay with having to wait a few days (my family isn’t!), especially if there are people worse than me, but so much anger at the reason,” he said. “These idiots that refused health care are now taking up my slot for heart surgery. It’s really aggravating.”

Anjali Bright, a spokesperson for St. Thomas West, provided a statement to this news organization saying they are not suspending elective procedures, but they are reviewing those “requiring an inpatient stay on a case-by-case basis.”

She emphasized, though, that “we will never delay care if the patient’s status changes to ‘urgent.’ ”

“Because of how infectious this variant is, this has the potential to be so much worse than what we saw in January,” said Donald Williamson, MD, president of the Alabama Hospital Association.

Dr. Williamson said they have modeled three possible scenarios for spread in the state, which ranks dead last in the United States for vaccination, with just 35% of its population fully protected. If the Delta variant spreads as it did in the United Kingdom, Alabama could see it hospitalize up to 3,000 people. 

“That’s the best scenario,” he said.

If it sweeps through the state as it did in India, Alabama is looking at up to 4,500 patients hospitalized, a number that would require more beds and more staff to care for patients.

Then, there is what Dr. Williamson calls his “nightmare scenario.” If the entire state begins to see transmission rates as high as they’re currently seeing in coastal Mobile and Baldwin counties, that could mean up to 8,000 people in the hospital.

“If we see R-naughts of 5-8 statewide, we’re in real trouble,” he said. The R-naught is the basic rate of reproduction, and it means that each infected person would go on to infect 5-8 others. Dr. Williamson said the federal government would have to send them more staff to handle that kind of a surge.
 

‘Sense of betrayal’

Unlike the surges of last winter and spring, which sent hospitals scrambling for beds and supplies, the biggest pain point for hospitals now is staffing.

In Mississippi, where 200 patients are parked in emergency departments waiting for available and staffed ICU beds, the state is facing Delta with 2,000 fewer registered nurses than it had during its winter surge. 

Some have left because of stress and burnout. Others have taken higher-paying jobs with travel nursing companies. To stop the exodus, hospitals are offering better pay, easier schedules, and sign-on and stay-on bonuses.

Doctors say the incentives are nice, but they don’t help with the anguish and anger many feel after months of battling COVID.

“There’s a big sense of betrayal,” said Sarah Nafziger, MD, vice president of clinical support services at the University of Alabama at Birmingham Hospital. “Our staff and health care workers, in general, feel like we’ve been betrayed by the community.”

“We have a vaccine, which is the key to ending this pandemic and people just refuse to take it, and so I think we’re very frustrated. We feel that our communities have let us down by not taking advantage of the vaccine,” Dr. Nafziger said. “It’s just baffling to me and it’s broken my heart every single day.”
