Large metropolitan areas, especially those in the Northeast, are already seeing a major increase in cases following Thanksgiving, and that trend is expected to continue.

“Why? Simply stated, the large amount of Thanksgiving travel and gatherings undermined the nation’s pandemic footing and has elevated disease burden in areas of the country that were fortunate to have lower case rates before the holidays,” the forecasters wrote.

Case numbers in New York City are expected to double throughout December, the forecasters said. Similar growth could happen across Boston, Philadelphia, and Baltimore.

Overall, COVID-19 cases, hospitalizations, and deaths are rising across the United States but remain below levels seen during the summer and last winter’s surges, according to the New York Times. The increase is still being driven by the Delta variant, though it remains unclear how the Omicron variant, which has been detected in 27 states, could affect the trends in the coming weeks.

During the past week, the United States has reported an average of more than 120,000 new cases each day, the newspaper reported, which is an increase of 38% from two weeks ago.

The daily average of COVID-19 hospitalizations is around 64,000, which marks an increase of 22% from two weeks ago. More than 1,300 deaths are being reported each day, which is up 26%.

Numerous states are reporting double the cases from two weeks ago, stretching across the country from states in the Northeast such as Connecticut and Rhode Island to southern states such as North Carolina and Texas and western states such as California.

The Great Lakes region and the Northeast are seeing some of the most severe increases, the newspaper reported. New Hampshire leads the United States in recent cases per capita, and Maine has reported more cases in the past week than in any other seven-day period during the pandemic.

Michigan has the country’s highest hospitalization rate, and federal medical teams have been sent to the state to help with the surge in patients, according to The Detroit News. Michigan’s top public health officials described the surge as a “critical” and “deeply concerning” situation on Dec. 10, and they requested 200 more ventilators from the Strategic National Stockpile.

Indiana, Maine, and New York have also requested aid from the National Guard, according to USA Today. Health officials in those states urged residents to get vaccines or booster shots and wear masks in indoor public settings.

The Omicron variant can evade some vaccine protection, but booster shots can increase efficacy and offer more coverage, Anthony Fauci, MD, director of the National Institute of Allergy and Infectious Diseases, said Dec. 12.

“If you want to be optimally protected, absolutely get a booster,” he said on ABC’s “This Week.”

In addition, New York Gov. Kathy Hochul has announced a statewide mask mandate, which will take effect Dec. 13. Masks will be required in all indoor public spaces and businesses, unless the location implements a vaccine requirement instead, the news outlet reported.

Nearly every patient with a myeloid malignancy seroconverted against COVID-19 after their second dose of the Moderna vaccine in a review of 46 patients at the Moffitt Cancer Center in Tampa, Fla.

Factors including age, gender, race, disease status, lower-intensity active treatment, baseline neutrophil and lymphocyte counts, and past history of stem cell transplant had no effects on seroconversion in the study, which, despite its small numbers, is one of the largest series to date among patients with myeloid cancers. The findings were reported at the annual meeting of the American Society of Hematology.

COVID vaccination “appears to induce a strong antibody response” in patients with acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS), unlike with B-cell malignancies. “It indicates we should be aggressive about vaccinating such patients,” said senior investigator Jeffrey Lancet, MD, a blood cancer specialist at Moffitt, when he presented the findings at the meeting.

Presentation moderator Laura Michaelis, MD, a hematologist-oncologist at the Medical College of Wisconsin, Milwaukee, agreed.

The “strong antibody response in this group,” coupled with its high risk for severe COVID, “confirm the importance of these patients getting vaccinated,” she said.

Thirty patients with AML and 16 with MDS were included in the review. Most patients were in remission at the time of vaccination, but a third were in active treatment, including six on hypomethylating agents, six on targeted therapies, two on luspatercept, and one on lenalidomide. Thirty-two patients (69.6%) were a median of 17 months past allogeneic stem cell transplant.

Overall, 69.6% of patients developed IgG against spike proteins after the first shot and 95.7% of patients after the second dose, with a large increase in titer levels from the first to the second dose, from a mean of 315 AU/mL to 3,806.5 AU/mL following the second dose.

“Lab and clinical variables did not affect the antibody positivity rate after the second dose,” but patients on steroids and other immunosuppressants seemed less likely to respond to the first shot, Dr. Lancet said.

The study, conducted in early 2021, did not include acutely ill patients or those undergoing cheomotherapy induction and other aggressive treatments, because such patients were not being vaccinated at Moffitt during the study period.

The investigators measured anti-spike IgG by ELISA at baseline, then again about a month after the first shot and a month after the second shot.

Side effects were common and typically mild, including injection site pain, fatigue, headache, and arm swelling. Two patients with AML relapsed after vaccination.

Patients were a median of 68 years old when they were vaccinated; 58.7% were men; and almost all of the subjects were White. The median time from diagnosis to the first shot was 2 years.

The next step in the project is to study the timing of vaccination and response to it among patients on aggressive treatment and to perform neutralizing antibody assays to correlate IgG response with protection from COVID.

No funding was reported for the study. Investigators had numerous industry ties, including Dr. Lancet, a consultant for Celgene/BMS, Millenium Pharma/Takeda, AbbVie, and other firms. Dr. Michaelis didn’t have any disclosures.

Factors associated with the worst COVID-19-related outcomes for patients with acute leukemias and myelodysplastic syndromes include neutropenia, pre-COVID-19 prognosis, and deferral of ICU care, results of an American Society of Hematology (ASH) COVID-19 registry study suggest.

Rates of severe COVID-19 were significantly higher among patients who had active disease or neutropenia at the time of their COVID-19 diagnosis. Mortality related to COVID-19 was linked to neutropenia, primary disease prognosis of less than 6 months, and deferral of recommended ICU care, study results show.

By contrast, mortality was not associated with active primary disease or its treatment, according to researcher Pinkal Desai, MD, MPH.

Taken together, these findings provide preliminary evidence to support the use of aggressive supportive treatment of COVID-19 in patients with acute leukemias and myelodysplastic syndromes, said Dr. Desai, a hematologist-oncologist with Weill Cornell Medicine and NewYork-Presbyterian in New York.

“If desired by patients, aggressive support for hospitalized patients with COVID-19 is appropriate, regardless of remission status, given the results of our study,” Dr. Desai said in a press conference during the annual meeting of the American Society of Hematology.

In non-cancer patient populations, advanced age and cytopenias have been associated with mortality related to COVID-19, Dr. Desai said. Likewise, patients with acute leukemias and myelodysplastic syndrome are generally older and have disease- or treatment-related cytopenias, which might affect the severity of and mortality from COVID-19, she added.

With that concern in mind, Dr. Desai and co-investigators looked at predictors of severe COVID-19 disease and death among patients in the ASH Research Collaborative (ASH RC) COVID-19 Registry for Hematology.

This registry was started in the early days of the pandemic to provide real-time observational COVID-19 data to clinicians, according to an ASH news release.

The analysis by Dr. Desai and co-authors included 257 patients with COVID-19 as determined by their physician, including 135 with a primary diagnosis of acute myeloid leukemia, 82 with acute lymphocytic leukemia, and 40 with myelodysplastic syndromes. Sixty percent of the patients were hospitalized due to COVID-19.

At the time of COVID-19 diagnosis, 46% of patients were in remission, and 44% had active disease, according to the report.

Both neutropenia and active disease status at COVID-19 diagnosis were linked to severe COVID-19, defined as ICU admission due to a COVID-19-related reason, according to results of multivariable analysis. Among patients with severe COVID-19, 67% had active disease, meaning just 33% were in remission, Dr. Desai noted.

In multivariable analysis, two factors were significantly associated with mortality, she added: having an estimated pre-COVID-19 prognosis from the primary disease of less than 6 months, and deferral of ICU care when it was recommended to the patient.

Mortality was 21% overall, higher than would be expected in a non-cancer population, Dr. Desai said. For patients with COVID-19 requiring hospitalization, the mortality rate was 34% and for those patients who did go to the ICU, the mortality rate was 68%.

By contrast, there was no significant association between mortality and active disease as compared to disease in remission, Dr. Desai noted in her presentation. Likewise, mortality was not associated with active treatment at the time of COVID-19 diagnosis as compared to no treatment.

The Leukemia & Lymphoma Society

Gwen Nichols, MD, executive vice president and chief medical officer of the Leukemia & Lymphoma Society, New York, said those are reassuring data for patients with acute leukemias and myelodysplastic syndromes and their healthcare providers.

“From our point of view, it helps us say, ‘do not stop your treatment because of worries about COVID-19—it’s more important that you treat your cancer,” Dr. Nichols said in an interview. “We now know we can help people through COVID-19, and I think this is just really important data to back that up,” she added.

The new Omicron variant could make it more likely that people will need a fourth coronavirus vaccine earlier than expected, Pfizer officials said on Dec. 8.

The standard two doses may be less effective against the variant, the company announced earlier in the day, and a booster dose increases neutralizing antibodies.

But the timeline might need to be moved up for a fourth dose. Previously, Pfizer CEO Albert Bourla, PhD, said another dose might be needed about a year after a third shot. Now the company’s scientists believe that a fourth shot, which targets the Omicron variant, could be required sooner.

“With Omicron, we need to wait and see because we have very little information. We may need it faster,” Dr. Bourla said on CNBC’s Squawk Box.

“But for right now, the most important thing is that we have winter in front of us,” he said. “From a healthcare perspective, it is important to understand that we need to be well-protected to go through the winter.”

A third dose should provide protection throughout the winter, Dr. Bourla said. That may buy time until the early spring to develop new shots that target Omicron, which Pfizer could have ready by March, according to  Bloomberg News.

As of the afternoon of Dec. 8, 43 people in 19 states had tested positive for the Omicron variant, according to The Associated Press. More than 75% had been vaccinated, and a third had had booster shots. About a third had traveled internationally.

Nearly all of them have had mild symptoms so far, the AP reported, with the most common symptoms being a cough, congestion, and fatigue. One person has been hospitalized, but no deaths have been reported so far.

The CDC is still trying to determine how the Omicron variant may affect the course of the pandemic and whether the strain is more contagious or causes more severe disease.

“What we generally know is the more mutations a variant has, the higher level you need your immunity to be,” Rochelle Walensky, MD, director of the CDC, told the AP.

“We want to make sure we bolster everybody’s immunity,” she said. “And that’s really what motivated the decision to expand our guidance [on boosters for all adults].”

The Omicron variant has been reported in 57 countries so far, World Health Organization officials reported Dec. 8, and they expect that number to continue growing.

“Certain features of Omicron, including its global spread and large number of mutations, suggest it could have a major impact on the course of the pandemic. Exactly what that impact will be is still difficult to know,” Tedros Adhanom Ghebreyesus, PhD, the World Health Organization’s director-general, said during a media briefing.

Several studies suggest that Omicron leads to a rapid increase in transmission, he said, though scientists are still trying to understand whether it can “outcompete Delta.” Data from South Africa also suggests a higher risk of reinfection with Omicron, though it appears to cause milder disease than Delta, he noted.

“Even though we still need answers to some crucial questions, we are not defenseless against Omicron or Delta,” he said. “The steps countries take today, and in the coming days and weeks, will determine how Omicron unfolds.”

“With Omicron, we need to wait and see because we have very little information. We may need it faster,” Dr. Bourla said on CNBC’s Squawk Box.

“But for right now, the most important thing is that we have winter in front of us,” he said. “From a healthcare perspective, it is important to understand that we need to be well-protected to go through the winter.”

A third dose should provide protection throughout the winter, Dr. Bourla said. That may buy time until the early spring to develop new shots that target Omicron, which Pfizer could have ready by March, according to  Bloomberg News.

As of the afternoon of Dec. 8, 43 people in 19 states had tested positive for the Omicron variant, according to The Associated Press. More than 75% had been vaccinated, and a third had had booster shots. About a third had traveled internationally.

Nearly all of them have had mild symptoms so far, the AP reported, with the most common symptoms being a cough, congestion, and fatigue. One person has been hospitalized, but no deaths have been reported so far.

The CDC is still trying to determine how the Omicron variant may affect the course of the pandemic and whether the strain is more contagious or causes more severe disease.

“What we generally know is the more mutations a variant has, the higher level you need your immunity to be,” Rochelle Walensky, MD, director of the CDC, told the AP.

“We want to make sure we bolster everybody’s immunity,” she said. “And that’s really what motivated the decision to expand our guidance [on boosters for all adults].”

The Omicron variant has been reported in 57 countries so far, World Health Organization officials reported Dec. 8, and they expect that number to continue growing.

“Certain features of Omicron, including its global spread and large number of mutations, suggest it could have a major impact on the course of the pandemic. Exactly what that impact will be is still difficult to know,” Tedros Adhanom Ghebreyesus, PhD, the World Health Organization’s director-general, said during a media briefing.

Several studies suggest that Omicron leads to a rapid increase in transmission, he said, though scientists are still trying to understand whether it can “outcompete Delta.” Data from South Africa also suggests a higher risk of reinfection with Omicron, though it appears to cause milder disease than Delta, he noted.

“Even though we still need answers to some crucial questions, we are not defenseless against Omicron or Delta,” he said. “The steps countries take today, and in the coming days and weeks, will determine how Omicron unfolds.”

The Food and Drug Administration has authorized booster doses of Pfizer’s COVID-19 vaccine, clearing the way for millions of teenagers to get a third dose of vaccine starting 6 months after their second dose.

The FDA said it was basing its emergency authorization of boosters for 16- and 17-year-olds on data from 200 individuals who were 18-55 years of age when they received a booster dose. They are requiring Pfizer to collect data on safety in postauthorization studies.

“The FDA has determined that the benefits of a single booster dose of the Pfizer-BioNTech COVID-19 Vaccine or Comirnaty outweigh the risks of myocarditis and pericarditis in individuals 16 and 17 years of age to provide continued protection against COVID-19 and the associated serious consequences that can occur including hospitalization and death,” the agency said in a news release.

Israel has been giving booster doses of Pfizer’s vaccine to everyone 12 and up since late August. Data from that country show that myocarditis cases continue to be very rare, even in younger age groups, and are mild and temporary.

The authorization comes as the effectiveness of the current vaccines against the new Omicron variant has become a point of intense scientific inquiry.

Early studies suggest that booster doses may be necessary to keep Omicron at bay, at least until new variant-specific vaccines are ready next spring.

Current evidence suggests that the protection of the vaccines is holding up well against severe disease and death, at least with Delta and early iterations of the virus.

How well they will do against Omicron, and how severe Omicron infections may be for different age groups, remain open questions.

On Dec. 8, the World Health Organization urged countries not to wait for all the science to come in, but to act now to contain any potential threat.

The first pieces of evidence on Omicron suggest that it is highly contagious, perhaps even more than Delta, though early reports suggest symptoms caused by this version of the new coronavirus may be less severe than in previous waves. Experts have cautioned that the true severity of Omicron infections isn’t yet known, since the first cases have been detected in younger people, who tend to have milder COVID-19 symptoms than those of adults and seniors.

“Vaccination and getting a booster when eligible, along with other preventive measures like masking and avoiding large crowds and poorly ventilated spaces, remain our most effective methods for fighting COVID-19,” Acting FDA Commissioner Janet Woodcock, MD, said in a news release. “As people gather indoors with family and friends for the holidays, we can’t let up on all the preventive public health measures that we have been taking during the pandemic. With both the Delta and Omicron variants continuing to spread, vaccination remains the best protection against COVID-19.”

In mid-November, the FDA authorized boosters of the Pfizer vaccine for all individuals 18 and older, but the agency held off on expanding the use of boosters for younger age groups, partly because they have the highest risk of myocarditis, a very rare side effect.

Myocarditis cases seem to be temporary, with patients making a full recovery, though they need to be monitored in the hospital. The risk of myocarditis with a COVID-19 infection is many times higher than it is from a vaccine.

There have been little data to support the need for boosters in this age group, because children and teens tend to experience milder COVID-19 disease, though they are still at risk for post–COVID-19 complications such as long COVID and a delayed reaction to the virus called Post Acute Sequelae of SARS-CoV2 Infection among Children, or PAS-C.

All that changed with the arrival of Omicron.

The Pfizer/BioNTech booster lowers the risk for confirmed illness, severe illness, and death from COVID-19, according to two large studies from Israel published Dec. 8, 2021, in the New England Journal of Medicine.

Both studies were completed before the advent of the Omicron variant.

In one study that included data on more than 4 million patients, led by Yinon M. Bar-On, MSc, of the Weizmann Institute of Science in Rehovot, Israel, the rate of confirmed SARS-CoV-2 infection was lower in the booster group than in the nonbooster group by a factor of about 10.

This was true across all five age groups studied (range among the groups [starting with age 16], 9.0-17.2).

The risk for severe COVID-19 in the primary analysis decreased in the booster group by a factor of 17.9 (95% confidence interval, 15.1-21.2), among those aged 60 years or older. Risk for severe illness in those ages 40-59 was lower by a factor of 21.7 (95% CI, 10.6-44.2).

Among the 60 and older age group, risk for death was also reduced by a factor of 14.7 (95% CI, 10.0-21.4).

Researchers analyzed data for the period from July 30 to Oct. 10, 2021, from the Israel Ministry of Health database on 4.69 million people at least 16 years old who had received two Pfizer doses at least 5 months earlier.

In the main analysis, the researchers compared the rates of confirmed COVID-19, severe disease, and death among those who had gotten a booster at least 12 days earlier with the rates in a nonbooster group.

The authors wrote: “Booster vaccination programs may provide a way to control transmission without costly social-distancing measures and quarantines. Our findings provide evidence for the short-term effectiveness of the booster dose against the currently dominant Delta variant in persons 16 years of age or older.”
 

Death risk down by 90%

A second study, led by Ronen Arbel, PhD, with the community medical services division, Clalit Health Services (CHS), Tel Aviv, which included more than 800,000 participants, also found mortality risk was greatly reduced among those who received the booster compared with those who didn’t get the booster.

Participants aged 50 years or older who received a booster at least 5 months after a second Pfizer dose had 90% lower mortality risk because of COVID-19 than participants who did not get the booster.

The adjusted hazard ratio for death as a result of COVID-19 in the booster group, as compared with the nonbooster group, was 0.10 (95% CI, 0.07-0.14; P < .001). Of the 843,208 eligible participants, 758,118 (90%) received the booster during the 54-day study period.

The study included all CHS members who were aged 50 years or older on the study start date and had received two Pfizer doses at least 5 months earlier. CHS covers about 52% of the Israeli population and is the largest of four health care organizations in Israel that provide mandatory health care.

The authors noted that, although the study period was only 54 days (Aug. 6–Sept. 29), during that time “the incidence of COVID-19 in Israel was one of the highest in the world.”

The authors of both original articles pointed out that the studies are limited by short time periods and that longer-term studies are needed to see how the booster shots stand up to known and future variants, such as Omicron.

None of the authors involved in both studies reported relevant financial relationships.

A raft of new studies that looked at the ability of Omicron to evade an array of currently available vaccines suggest a substantial loss of protection against the highly mutated variant.

Medscape Illustration/Dreamstime

The new studies, from teams of researchers in Germany, South Africa, Sweden, and the drug company Pfizer, showed 25 to 40-fold drops in the ability of antibodies created by two doses of the Pfizer-BioNTech vaccine to neutralize the virus.  

But there seemed to be a bright spot in the studies too. The virus didn’t completely escape the immunity from the vaccines, and giving a third, booster dose appeared to restore antibodies to a level that’s been associated with protection against variants in the past.

“One of the silver linings of this pandemic so far is that mRNA vaccines manufactured based on the ancestral SARS-CoV-2 continue to work in the laboratory and, importantly, in real life against variant strains,” said Hana El Sahly, MD, professor of molecular virology and microbiology at Baylor College of Medicine in Houston. “The strains so far vary by their degree of being neutralized by the antibodies from these vaccines, but they are being neutralized nonetheless.” 

Dr. El Sahly points out that the Beta variant was associated with a 10-fold drop in antibodies, but two doses of the vaccines still protected against it.

President Biden hailed the study results as good news.

“That Pfizer lab report came back saying that the expectation is that the existing vaccines protect against Omicron. But if you get the booster, you’re really in good shape. And so that’s very encouraging,” he said in a press briefing Dec. 8.
 

More research needed

Other scientists, however, stressed that these studies are from lab tests, and don’t necessarily reflect what will happen with Omicron in the real world. They cautioned about a worldwide push for boosters with so many countries still struggling to give first doses of vaccines.

Soumya Swaminathan, MD, chief scientist for the World Health Organization, stressed in a press briefing Dec. 8 that the results from the four studies varied widely, showing dips in neutralizing activity with Omicron that ranged from 5-fold to 40-fold.

The types of lab tests that were run were different, too, and involved small numbers of blood samples from patients.

She stressed that immunity depends not just on neutralizing antibodies, which act as a first line of defense when a virus invades, but also on B cells and T cells, and so far, tests show that these crucial components — which are important for preventing severe disease and death — had been less impacted than antibodies.

“So, I think it’s premature to conclude that this reduction in neutralizing activity would result in a significant reduction in vaccine effectiveness,” she said.

Whether or not these first-generation vaccines will be enough to stop Omicron, though, remains to be seen. A study of the Pfizer, Moderna, and AstraZeneca vaccines, led by German physician Sandra Ciesek, MD, who directs the Institute of Medical Virology at the University of Frankfurt, shows a booster didn’t appear to hold up well over time.

Dr. Ciesek and her team exposed Omicron viruses to the antibodies of volunteers who had been boosted with the Pfizer vaccine 3 months prior.  

She also compared the results to what happened to those same 3-month antibody levels against Delta variant viruses. She found only a 25% neutralization of Omicron compared with a 95% neutralization of Delta. That represented about a 37-fold reduction in the ability of the antibodies to neutralize Omicron vs Delta.

“The data confirm that developing a vaccine adapted for Omicron makes sense,” she tweeted as part of a long thread she posted on her results.
 

Retool the vaccines?

Both Pfizer and Moderna are retooling their vaccines to better match them to the changes in the Omicron variant. In a press release, Pfizer said it could start deliveries of that updated vaccine by March, pending U.S. Food and Drug Administration authorization.

“What the booster really does in neutralizing Omicron right now, they don’t know, they have no idea,” said Peter Palese, PhD, chair of the department of microbiology at the Mount Sinai School of Medicine in New York City.

Dr. Palese said he was definitely concerned about a possible Omicron wave.

“There are four major sites on the spike protein targeted by antibodies from the vaccines, and all four sites have mutations,” he said. “All these important antigenic sites are changed.

“If Omicron becomes the new Delta, and the old vaccines really aren’t good enough, then we have to make new Omicron vaccines. Then we have to revaccinate everybody twice,” he said, and the costs could be staggering. “I am worried.”

Tedros Adhanom Ghebreyesus, PhD, director general of the WHO, urged countries to move quickly.

“Don’t wait. Act now,” he said, even before all the science is in hand. “All of us, every government, every individual should use all the tools we have right now,” to drive down transmission, increase testing and surveillance, and share scientific findings.

“We can prevent Omicron [from] becoming a global crisis right now,” he said.

The types of lab tests that were run were different, too, and involved small numbers of blood samples from patients.

She stressed that immunity depends not just on neutralizing antibodies, which act as a first line of defense when a virus invades, but also on B cells and T cells, and so far, tests show that these crucial components — which are important for preventing severe disease and death — had been less impacted than antibodies.

“So, I think it’s premature to conclude that this reduction in neutralizing activity would result in a significant reduction in vaccine effectiveness,” she said.

Whether or not these first-generation vaccines will be enough to stop Omicron, though, remains to be seen. A study of the Pfizer, Moderna, and AstraZeneca vaccines, led by German physician Sandra Ciesek, MD, who directs the Institute of Medical Virology at the University of Frankfurt, shows a booster didn’t appear to hold up well over time.

Dr. Ciesek and her team exposed Omicron viruses to the antibodies of volunteers who had been boosted with the Pfizer vaccine 3 months prior.  

She also compared the results to what happened to those same 3-month antibody levels against Delta variant viruses. She found only a 25% neutralization of Omicron compared with a 95% neutralization of Delta. That represented about a 37-fold reduction in the ability of the antibodies to neutralize Omicron vs Delta.

“The data confirm that developing a vaccine adapted for Omicron makes sense,” she tweeted as part of a long thread she posted on her results.
 

Retool the vaccines?

Both Pfizer and Moderna are retooling their vaccines to better match them to the changes in the Omicron variant. In a press release, Pfizer said it could start deliveries of that updated vaccine by March, pending U.S. Food and Drug Administration authorization.

“What the booster really does in neutralizing Omicron right now, they don’t know, they have no idea,” said Peter Palese, PhD, chair of the department of microbiology at the Mount Sinai School of Medicine in New York City.

Dr. Palese said he was definitely concerned about a possible Omicron wave.

“There are four major sites on the spike protein targeted by antibodies from the vaccines, and all four sites have mutations,” he said. “All these important antigenic sites are changed.

“If Omicron becomes the new Delta, and the old vaccines really aren’t good enough, then we have to make new Omicron vaccines. Then we have to revaccinate everybody twice,” he said, and the costs could be staggering. “I am worried.”

Tedros Adhanom Ghebreyesus, PhD, director general of the WHO, urged countries to move quickly.

“Don’t wait. Act now,” he said, even before all the science is in hand. “All of us, every government, every individual should use all the tools we have right now,” to drive down transmission, increase testing and surveillance, and share scientific findings.

“We can prevent Omicron [from] becoming a global crisis right now,” he said.

A raft of new studies that looked at the ability of Omicron to evade an array of currently available vaccines suggest a substantial loss of protection against the highly mutated variant.

The new studies, from teams of researchers in Germany, South Africa, Sweden, and the drug company Pfizer, showed 25 to 40-fold drops in the ability of antibodies created by two doses of the Pfizer-BioNTech vaccine to neutralize the virus.  

But there seemed to be a bright spot in the studies too. The virus didn’t completely escape the immunity from the vaccines, and giving a third, booster dose appeared to restore antibodies to a level that’s been associated with protection against variants in the past.

“One of the silver linings of this pandemic so far is that mRNA vaccines manufactured based on the ancestral SARS-CoV-2 continue to work in the laboratory and, importantly, in real life against variant strains,” said Hana El Sahly, MD, professor of molecular virology and microbiology at Baylor College of Medicine in Houston. “The strains so far vary by their degree of being neutralized by the antibodies from these vaccines, but they are being neutralized nonetheless.” 

Dr. El Sahly points out that the Beta variant was associated with a 10-fold drop in antibodies, but two doses of the vaccines still protected against it.

President Biden hailed the study results as good news.

“That Pfizer lab report came back saying that the expectation is that the existing vaccines protect against Omicron. But if you get the booster, you’re really in good shape. And so that’s very encouraging,” he said in a press briefing Dec. 8.

Adolescents and adults younger than age 21 who develop myocarditis after mRNA COVID-19 vaccination frequently have abnormal findings on cardiac MRI (cMRI) but most have a mild clinical course with rapid resolution of symptoms, a new study concludes.

• Most patients were male (90.6%), White (66.2%) and with a median age of 15.8 years.
• Suspected myocarditis occurred in 136 patients (97.8%) following mRNA vaccine, with 131 (94.2%) following the Pfizer-BioNTech vaccine; 128 cases (91.4%) occurred after the second dose.
• Symptoms started a median of 2 days (range 0 to 22 days) following vaccination administration.
• Chest pain was the most common symptom (99.3%), with fever present in 30.9% of patients and shortness of breath in 27.3%.
• Patients were treated with nonsteroidal anti-inflammatory drugs (81.3%), intravenous immunoglobulin (21.6%), glucocorticoids (21.6%), colchicine (7.9%) or no anti-inflammatory therapies (8.6%).
• Twenty-six patients (18.7%) were admitted to the intensive care unit; 2 received inotropic/vasoactive support; none required extracorporeal membrane oxygenation or died.
• Median time spent in the hospital was 2 days.
• A total of 111 patients had elevated troponin I (8.12 ng/mL) and 28 had elevated troponin T (0.61 ng/mL).
• More than two-thirds (69.8%) had abnormal electrocardiograms and/or arrhythmias (7 with nonsustained ventricular tachycardia).
• Twenty-six patients (18.7%) had left ventricular ejection fraction (LVEF) less than 55% on echocardiogram; LVEF had returned to normal in the 25 who returned for follow-up.
• 75 of 97 patients (77.3%) who underwent cMRI at a median of 5 days from symptom onset had abnormal findings; 74 (76.3%) had late gadolinium enhancement, 54 (55.7%) had myocardial edema, and 49 (50.5%) met Lake Louise criteria for myocarditis.

“These data suggest that most cases of suspected COVID-19 vaccine–related myocarditis in people younger than 21 are mild and resolve quickly,” corresponding author Dongngan Truong, MD, Division of Pediatric Cardiology, University of Utah and Primary Children’s Hospital, Salt Lake City, said in a statement.

“We were very happy to see that type of recovery. However, we are awaiting further studies to better understand the long-term outcomes of patients who have had COVID-19 vaccination-related myocarditis. We also need to study the risk factors and mechanisms for this rare complication,” Dr. Truong added.

Dr. Lloyd-Jones said these findings support the AHA’s position that COVID-19 vaccines are “safe, highly effective, and fundamental to saving lives, protecting our families and communities against COVID-19, and ending the pandemic.”

The study received no funding. Dr. Truong consults for Pfizer on vaccine-associated myocarditis. A complete list of author disclosures is available with the original article.

An abstract and poster presentation questioning the safety of mRNA-based COVID-19 vaccines, embraced by some and lambasted by others, has drawn an “expression of concern” from the American Heart Association, along with a bid for correction.

The abstract in question concludes that COVID vaccines “dramatically increase” levels of certain inflammatory biomarkers, and therefore, the 5-year risk of acute coronary syndromes (ACS), based on pre- and post-vaccination results of an obscure blood panel called the PULS Cardiac Test (GD Biosciences). The findings were presented at the AHA’s 2021 Scientific Sessionsas, an uncontrolled observational study of 566 patients in a preventive cardiology practice.

Some on social media have seized on the abstract as evidence of serious potential harm from the two available mRNA-based SARS-CoV-2 vaccines, BNT162b2 (Pfizer-BioNTech) and mRNA-1273 (Moderna). But others contend that the study’s described design and findings are specious and its conclusions overstated.

They also point to the notoriety of its one listed author, Steven R. Gundry, MD, who promotes his diet books and supplements as well as fringe, highly criticized theories about diet and disease on several websites, including drgundry.com. Dr. Gundry has not responded to requests for an interview.

Dr. Gundry’s abstract from the AHA Scientific Sessions 2021, available on the meeting’s program planner, was marked with an “expression of concern” by the AHA that is to stand “until a suitable correction is published, to indicate that the abstract in its current version may not be reliable.”

The expression of concern statement, also published online Nov. 24 in Circulation, says “potential errors in the abstract” were brought to the attention of the meeting planners. “Specifically, there are several typographical errors, there is no data in the abstract regarding myocardial T-cell infiltration, there are no statistical analyses for significance provided, and the author is not clear that only anecdotal data was used.”

The biomarker elevations on which the abstract’s conclusions are based included hepatocyte growth factor, “which serves as a marker for chemotaxis of T-cells into epithelium and cardiac tissue,” it states.

“The expression of concern about the abstract will remain in place until a correction is accepted and published” in Circulation, AHA spokesperson Suzanne Grant told this news organization by email.

“The specific data needed will be up to the abstract author to determine and supply,” she said, noting that Dr. Gundry “has been in communication with the journal throughout this process.”

Submitting researchers “must always attest to the validity of the abstract,” Ms. Grant said. “Abstracts are then curated by independent review panels, blinded to the identities of the abstract authors, and are considered based on the potential to add to the diversity of scientific issues and views discussed at the meeting.”

Regarding the AHA’s system for vetting abstracts vying for acceptance to the scientific sessions, she said it is not primarily intended to “evaluate scientific validity” and that the organization is “currently reviewing its existing abstract submission processes.”

A recent Reuters report reviews the controversy and provides links to criticisms of the study on social media.

Louisiana Gov. John Bel Edwards says the state government plans to make the COVID-19 vaccine a required immunization for students 16 and older in the state’s public school system.

“I just think it’s really, really important to embrace the science and really it’s also important to not engage in misinformation,” said Gov. Edwards, a Democrat, according to The Advocate. “Absent some compelling reason, which I at present have not seen, I fully expect that we will be adding the vaccine to the schedule.”

Parents could opt out their children from the requirement with a letter from a medical provider or a simple signature in dissent, The Advocate reported. The new rule would go into effect at the start of the 2022 school year and at first would apply to students aged 16 and older.

Republican legislators voiced their opposition to the COVID-19 vaccine requirement at a hearing on Dec. 6, calling it unneeded and an example of governmental overreach.

“I believe the vaccine should be highly recommended but not mandated,” state Rep. Laurie Schlegel said, according to TV station WDSU.

State Sen. Cameron Henry of Metairie said he received “hundreds of emails” from parents asking him to prevent the rule from going into effect, WDSU said.

WDSU said the governor can overrule the committee if it rejects the proposed vaccine rule.

Louisiana State Health Officer Joseph Kanter, MD, testified on Dec. 6 that 18 children had died of COVID-19 in Louisiana and many others had become sick because of it.

“I can’t think of another disease on that childhood schedule that we’ve lost that many kids from. In my mind, it’s very much in the public interest. But it’s the family and the parents’ decision,” Dr. Kanter said.

The addition of the vaccine is being proposed by the Louisiana Department of Health, which has added other vaccines to the required list over the years. In 2015, the legislature added meningitis as a required shot with no controversy, The Advocate said.
