Q&A: What to know about the new BA 2.86 COVID variant
The Centers for Disease Control and Prevention and the World Health Organization have dubbed the BA 2.86 variant of COVID-19 as a variant to watch.
So far, only 26 cases of “Pirola,” as the new variant is being called, have been identified: 10 in Denmark, four each in Sweden and the United States, three in South Africa, two in Portugal, and one each the United Kingdom, Israel, and Canada. BA 2.86 is a subvariant of Omicron, but according to reports from the CDC, the strain has many more mutations than the ones that came before it.
With so many facts still unknown about this new variant, this news organization asked experts what people need to be aware of as it continues to spread.
What is unique about the BA 2.86 variant?
“It is unique in that it has more than three mutations on the spike protein,” said Purvi S. Parikh, MD, an infectious disease expert at New York University’s Langone Health. The virus uses the spike proteins to enter our cells.
This “may mean it will be more transmissible, cause more severe disease, and/or our vaccines and treatments may not work as well, as compared to other variants,” she said.
What do we need to watch with BA 2.86 going forward?
“We don’t know if this variant will be associated with a change in the disease severity. We currently see increased numbers of cases in general, even though we don’t yet see the BA.2.86 in our system,” said Heba Mostafa, PhD, director of the molecular virology laboratory at Johns Hopkins Hospital in Baltimore.
“It is important to monitor BA.2.86 (and other variants) and understand how its evolution impacts the number of cases and disease outcomes,” she said. “We should all be aware of the current increase in cases, though, and try to get tested and be treated as soon as possible, as antivirals should be effective against the circulating variants.”
What should doctors know?
Dr. Parikh said doctors should generally expect more COVID cases in their clinics and make sure to screen patients even if their symptoms are mild.
“We have tools that can be used – antivirals like Paxlovid are still efficacious with current dominant strains such as EG.5,” she said. “And encourage your patients to get their boosters, mask, wash hands, and social distance.”
How well can our vaccines fight BA 2.86?
“Vaccine coverage for the BA.2.86 is an area of uncertainty right now,” said Dr. Mostafa.
In its report, the CDC said scientists are still figuring out how well the updated COVID vaccine works. It’s expected to be available in the fall, and for now, they believe the new shot will still make infections less severe, new variants and all.
Prior vaccinations and infections have created antibodies in many people, and that will likely provide some protection, Dr. Mostafa said. “When we experienced the Omicron wave in December 2021, even though the variant was distant from what circulated before its emergence and was associated with a very large increase in the number of cases, vaccinations were still protective against severe disease.”
What is the most important thing to keep track of when it comes to this variant?
According to Dr. Parikh, “it’s most important to monitor how transmissible [BA 2.86] is, how severe it is, and if our current treatments and vaccines work.”
Dr. Mostafa said how well the new variants escape existing antibody protection should also be studied and watched closely.
What does this stage of the virus mutation tell us about where we are in the pandemic?
The history of the coronavirus over the past few years shows that variants with many changes evolve and can spread very quickly, Dr. Mostafa said. “Now that the virus is endemic, it is essential to monitor, update vaccinations if necessary, diagnose, treat, and implement infection control measures when necessary.”
With the limited data we have so far, experts seem to agree that while the variant’s makeup raises some red flags, it is too soon to jump to any conclusions about how easy it is to catch it and the ways it may change how the virus impacts those who contract it.

Five questions for COVID experts: How concerned should we be?
COVID-19 hospitalizations have been on the rise for weeks as summer nears its end, but how concerned should you be? SARS-CoV-2, the virus behind COVID, continues to evolve and surprise us. So COVID transmission, hospitalization, and death rates can be difficult to predict.
Question 1: Are you expecting an end-of-summer COVID wave to be substantial?
Eric Topol, MD: “This wave won’t likely be substantial and could be more of a ‘wavelet.’ I’m not thinking that physicians are too concerned,” said Dr. Topol, founder and director of Scripps Research Translational Institute in La Jolla, Calif.
Thomas Gut, DO: “It’s always impossible to predict the severity of COVID waves. Although the virus has generally mutated in ways that favor easier transmission and milder illness, there have been a handful of surprising mutations that were more dangerous and deadly than the preceding strain,” said Dr. Gut, associate chair of medicine at Staten Island University Hospital/Northwell Health in New York.
Robert Atmar, MD: “I’ll start with the caveat that prognosticating for SARS-CoV-2 is a bit hazardous as we remain in unknown territory for some aspects of its epidemiology and evolution,” said Dr. Atmar, a professor of infectious diseases at Baylor College of Medicine in Houston. “It depends on your definition of substantial. We, at least in Houston, are already in the midst of a substantial surge in the burden of infection, at least as monitored through wastewater surveillance. The amount of virus in the wastewater already exceeds the peak level we saw last winter. That said, the increased infection burden has not translated into large increases in hospitalizations for COVID-19. Most persons hospitalized in our hospital are admitted with infection, not for the consequences of infection.”
Stuart Campbell Ray, MD: “It looks like there is a rise in infections, but the proportional rise in hospitalizations from severe cases is lower than in the past, suggesting that folks are protected by the immunity we’ve gained over the past few years through vaccination and prior infections. Of course, we should be thinking about how that applies to each of us – how recently we had a vaccine or COVID-19, and whether we might see more severe infections as immunity wanes,” said Dr. Ray, who is a professor of medicine in the division of infectious diseases at Johns Hopkins University in Baltimore.
Question 2: Is a return to masks or mask mandates coming this fall or winter?
Dr. Topol: “Mandating masks doesn’t work very well, but we may see wide use again if a descendant of [variant] BA.2.86 takes off.”
Dr. Gut: “It’s difficult to predict if there are any mask mandates returning at any point. Ever since the Omicron strains emerged, COVID has been relatively mild, compared to previous strains, so there probably won’t be any plan to start masking in public unless a more deadly strain appears.”
Dr. Atmar: “I do not think we will see a return to mask mandates this fall or winter for a variety of reasons. The primary one is that I don’t think the public will accept mask mandates. However, I think masking can continue to be an adjunctive measure to enhance protection from infection, along with booster vaccination.”
Dr. Ray: “Some people will choose to wear masks during a surge, particularly in situations like commuting where they don’t interfere with what they’re doing. They will wear masks particularly if they want to avoid infection due to concerns about others they care about, disruption of work or travel plans, or concerns about long-term consequences of repeated COVID-19.”
Question 3: Now that COVID testing and vaccinations are no longer free of charge, how might that affect their use?
Dr. Topol: “It was already low, and this will undoubtedly further compromise their uptake.”
Dr. Gut: “I do expect that testing will become less common now that tests are no longer free. I’m sure there will be a lower amount of detection in patients with milder or asymptomatic disease compared to what we had previously.”
Dr. Atmar: “If there are out-of-pocket costs for the SARS-CoV-2 vaccine, or if the administrative paperwork attached to getting a vaccine is increased, the uptake of SARS-CoV-2 vaccines will likely decrease. It will be important to communicate to the populations targeted for vaccination the potential benefits of such vaccination.”
Dr. Ray: “A challenge with COVID-19, all along, has been disparities in access to care, and this will be worse without public support for prevention and testing. This applies to everyone but is especially burdensome for those who are often marginalized in our health care system and society in general. I hope that we’ll find ways to ensure that people who need tests and vaccinations are able to access them, as good health is in everyone’s interest.”
Question 4: Will the new vaccines against COVID work for the currently circulating variants?
Dr. Topol: “The XBB.1.5 boosters will be out Sept. 14. They should help versus EG.5.1 and FL.1.5.1. The FL.1.5.1 variant is gaining now.”
Dr. Gut: “In the next several weeks, we expect the newer monovalent XBB-based vaccines to be offered that offer good protection against current circulating COVID variants along with the new Eris variant.”
Dr. Atmar: “The vaccines are expected to induce immune responses to the currently circulating variants, most of which are strains that evolved from the vaccine strain. The vaccine is expected to be most effective in preventing severe illness and will likely be less effective in preventing infection and mild illness.”
Dr. Ray: “Yes, the updated vaccine design has a spike antigen (XBB.1.5) nearly identical to the current dominant variant (EG.5). Even as variants change, the boosters stimulate B cells and T cells to help protect in a way that is safer than getting COVID-19 infection.”
Question 5: Is there anything we should watch out for regarding the BA.2.86 variant in particular?
Dr. Topol: “The scenario could change if there are new functional mutations added to it.”
Dr. Gut: “BA.2.86 is still fairly uncommon and does not have much data to directly make any informed guesses. However, in general, people that have been exposed to more recent mutations of the COVID virus have been shown to have more protection from newer upcoming mutations. It’s fair to guess that people that have not had recent infection from COVID, or have not had a recent booster, are at higher risk for being infected by any XBB- or BA.2-based strains.”
Dr. Atmar: BA.2.86 has been designated as a variant under monitoring. We will want to see whether it becomes more common and if there are any unexpected characteristics associated with infection by this variant.”
Dr. Ray: “It’s still rare, but it’s been seen in geographically dispersed places, so it’s got legs. The question is how effectively it will bypass some of the immunity we’ve gained. T cells are likely to remain protective, because they target so many parts of the virus that change more slowly, but antibodies from B cells to spike protein may have more trouble recognizing BA.2.86, whether those antibodies were made to a vaccine or a prior variant.”

Severe COVID may cause long-term cellular changes: Study
The small study, published in Cell and funded by the National Institutes of Health, details how immune cells were analyzed through blood samples collected from 38 patients recovering from severe COVID and other critical illnesses, and from 19 healthy people. Researchers from Weill Cornell Medicine, New York, and The Jackson Laboratory for Genomic Medicine, Farmington, Conn., found through isolating hematopoietic stem cells that people recovering from severe bouts of COVID had changes to their DNA that were passed down to offspring cells.
The research team, led by Steven Josefowicz, PhD, of Weill Cornell’s pathology department, and Duygu Ucar, PhD, associate professor at The Jackson Laboratory for Genomic Medicine, discovered that this chain reaction of stem cell changes caused a boost in the production of monocytes. The authors found that, due to the innate cellular changes from a severe case of COVID, patients in recovery ended up producing a larger amount of inflammatory cytokines, rather than monocytes – distinct from samples collected from healthy patients and those recovering from other critical illnesses.
These changes to patients’ epigenetic landscapes were observed even a year after the initial COVID-19 infection. While the small participant pool meant that the research team could not establish a direct line between these innate changes and any ensuing health outcomes, the research provides us with clues as to why patients continue to struggle with inflammation and long COVID symptoms well after they recover.
While the authors reiterate the study’s limitations and hesitate to make any clear-cut associations between the results and long-term health outcomes, Wolfgang Leitner, PhD, from the NIH’s National Institute of Allergy and Infectious Diseases, predicts that long COVID can, at least in part, be explained by the changes in innate immune responses.
“Ideally, the authors would have had cells from each patient before they got infected, as a comparator, to see what the epigenetic landscape was before COVID changed it,” said Dr. Leitner. “Clear links between the severity of COVID and genetics were discovered already early in the pandemic and this paper should prompt follow-up studies that link mutations in immune genes with the epigenetic changes described here.”
Dr. Leitner said he had some initial predictions about the long-term impact of COVID-19, but he had not anticipated some of what the study’s findings now show.
“Unlike in the case of, for example, influenza, where the lungs go into ‘repair mode’ after the infection has been resolved – which leaves people susceptible to secondary infections for up to several months – this study shows that after severe COVID, the immune system remains in ‘emergency mode’ and in a heightened state of inflammation,” said Dr. Leitner.
“That further aggravates the problem the initial strong inflammation causes: even higher risk of autoimmune disease, but also, cancer.”
Commenting on the findings, Eric Topol, MD, editor-in-chief of Medscape Medical News, said the study presents “evidence that a key line of immune cells are essentially irrevocably, epigenetically altered and activated.
“You do not want to have this [COVID],” he added.
The study also highlights the researchers’ novel approach to isolating hematopoietic stem cells, found largely in bone marrow. This type of research has been limited in the past because of how costly and invasive it can be to analyze cells in bone marrow. But, by isolating and enriching hematopoietic stem cells, the team can decipher the full cellular diversity of the cells’ bone marrow counterparts.
“This revelation opened the doors to study, at single-cell resolution, how stem cells are affected upon infection and vaccination with a simple blood draw,” representatives from the Jackson lab said in a press release.

The small study, published in Cell and funded by the National Institutes of Health, details how immune cells were analyzed through blood samples collected from 38 patients recovering from severe COVID and other critical illnesses, and from 19 healthy people. Researchers from Weill Cornell Medicine, New York, and The Jackson Laboratory for Genomic Medicine, Farmington, Conn., found through isolating hematopoietic stem cells that people recovering from severe bouts of COVID had changes to their DNA that were passed down to offspring cells.
The research team, led by Steven Josefowicz, PhD, of Weill Cornell’s pathology department, and Duygu Ucar, PhD, associate professor at The Jackson Laboratory for Genomic Medicine, discovered that this chain reaction of stem cell changes caused a boost in the production of monocytes. The authors found that, due to the innate cellular changes from a severe case of COVID, patients in recovery ended up producing a larger amount of inflammatory cytokines, rather than monocytes – distinct from samples collected from healthy patients and those recovering from other critical illnesses.
These changes to patients’ epigenetic landscapes were observed even a year after the initial COVID-19 infection.

Use of mental health services soared during pandemic
By the end of August 2022, overall use of mental health services was almost 40% higher than before the COVID-19 pandemic, while spending increased by 54%, according to a new study by researchers at the RAND Corporation.
During the early phase of the pandemic, from mid-March to mid-December 2020, before the vaccine was available, in-person visits decreased by 40%, while telehealth visits increased by 1,000%, reported Jonathan H. Cantor, PhD, and colleagues at RAND, and at Castlight Health, a benefit coordination provider, in a paper published online in JAMA Health Forum.
Between December 2020 and August 2022, telehealth visits stayed stable, but in-person visits creeped back up, eventually reaching 80% of prepandemic levels. However, “total utilization was higher than before the pandemic,” Dr. Cantor, a policy researcher at RAND, told this news organization.
“It could be that it’s easier for individuals to receive care via telehealth, but it could also just be that there’s a greater demand or need since the pandemic,” said Dr. Cantor. “We’ll just need more research to actually unpack what’s going on,” he said.
Initial per capita spending increased by about a third and was up overall by more than half. But it’s not clear how much of that is due to utilization or to price of services, said Dr. Cantor. Spending for telehealth services remained stable in the post-vaccine period, while spending on in-person visits returned to prepandemic levels.
Dr. Cantor and his colleagues were not able to determine whether utilization was by new or existing patients, but he said that would be good data to have. “It would be really important to know whether or not folks are initiating care because telehealth is making it easier,” he said.
The authors analyzed about 1.5 million claims for anxiety disorders, major depressive disorder, bipolar disorder, schizophrenia, and posttraumatic stress disorder, out of claims submitted by 7 million commercially insured adults whose self-insured employers used the Castlight benefit.
Dr. Cantor noted that this is just a small subset of the U.S. population. He said he’d like to have data from Medicare and Medicaid to fully assess the impact of the COVID-19 pandemic on mental health and of telehealth visits.
“This is a still-burgeoning field,” he said about telehealth. “We’re still trying to get a handle on how things are operating, given that there’s been so much change so rapidly.”
Meanwhile, 152 major employers responding to a large national survey this summer said that they’ve been grappling with how COVID-19 has affected workers. The employers include 72 Fortune 100 companies and provide health coverage for more than 60 million workers, retirees, and their families.
Seventy-seven percent said they are currently seeing an increase in depression, anxiety, and substance use disorders as a result of the pandemic, according to the Business Group on Health’s survey. That’s up from 44% in 2022.
Going forward, employers will focus on increasing access to mental health services, the survey reported.
“Our survey found that in 2024 and for the near future, employers will be acutely focused on addressing employees’ mental health needs while ensuring access and lowering cost barriers,” Ellen Kelsay, president and CEO of Business Group on Health, said in a statement.
The study was supported by grants from the National Institute of Mental Health and the National Institute on Aging. Coauthor Dena Bravata, MD, a Castlight employee, reported receiving personal fees from Castlight Health during the conduct of the study. Coauthor Christopher M. Whaley, a RAND employee, reported receiving personal fees from Castlight Health outside the submitted work.

New COVID strain may evade vaccines, alarming health officials
The strain is called BA.2.86 and is of particular concern because of its more than 30 mutations, which means it may behave very differently than previous versions of the virus. That number of mutations is on par with the difference between variants so serious that they were formally named, such as between Delta and Omicron, the CDC explained in the risk assessment issued Aug. 23.
Worldwide, health agencies are issuing a flurry of updates on BA.2.86. The strain only recently landed on the World Health Organization’s radar when it was named a “variant under monitoring” on Aug. 17. The CDC announced the same day that it had been detected in the United States.
Among the characteristics the CDC monitors for are how contagious a strain is, how well it responds to treatment, and how severely it affects people.
“BA.2.86 may be more capable of causing infection in people who have previously had COVID-19 or who have received COVID-19 vaccines,” the CDC risk assessment stated.
The agency is evaluating how well the forthcoming updated vaccine, due out in September, performs against BA.2.86.
A new forecast also released this week by the CDC predicts hospitalizations due to the virus will continue their upward trend through at least mid-September. Currently, about 1,800 people are hospitalized daily with COVID-19. The new prediction shows that number has a small potential to drop as low as 1,100 daily, but it could also increase by as many as 7,500 per day. The most likely scenario lands somewhere in the middle of that range, with daily hospital admissions of between 2,000 and 4,000 people by Sept. 18.
The CDC said there is “no evidence” that BA.2.86 is causing more severe illness but said that could change as more information becomes available. Health experts typically gauge severity by the rate of COVID hospitalizations.
The journal Nature reported that many scientists see similarities between the emergence of BA.2.86 and that of Omicron, which rapidly spread around the world in late 2021.
“There’s a little bit of déjà vu all over again,” University of Michigan virologist Adam Lauring, MD, PhD, whose lab detected one of the first U.S. cases of BA.2.86, told Nature.
Dr. Lauring, as well as the CDC and the WHO, all caution that more data is needed to truly understand the threat posed by BA.2.86.
“There’s good reason to think it won’t be like the Omicron wave, but it’s early days,” Dr. Lauring said.

COVID vax: Primary care back at forefront of care delivery
With COVID-19 hospitalizations up by 22% and deaths up by 8% as of Aug. 12, primary care clinicians are readying to distribute the new COVID-19 booster that is expected to arrive in September.
David Cutler, MD, is hoping to vaccinate as many of his patients who want the shots. He and other primary care clinicians are finally back in the business of prevention after being sidelined during the pandemic.
Most primary care clinicians weren’t provided with the vaccine through the height of the pandemic, when federal officials instead focused their efforts on vaccine distribution through hospital systems and retail pharmacies. The consequence, primary care clinicians say, is that they have no records for patients who need the vaccine; they cannot send patients reminders; and they have no idea if an at-risk patient is ready for a booster.
“The role of primary care is educating people about COVID-19, testing for COVID-19 and other infections, providing access to vaccines and treatment, and sustaining our health care system to provide care, fight disease, and save lives,” said Dr. Cutler, a family physician at Providence Saint John’s Health Center in Santa Monica, Calif.
A study published in Health Affairs confirmed that primary care practices were not included in the federal vaccine strategy. The researchers found that by the end of 2021, 43.1% of 2,000 primary care practices had no records of COVID-19 vaccinations for patients. More than 90% had records for historically routine immunizations, such as influenza and shingles.
“I do believe if PCPs had earlier access to the vaccine, we could have done a better job vaccinating more people,” said Ann Greiner, MCP, president and chief executive officer of the Primary Care Collaborative, a nonprofit organization. “We need to make sure they’re back in that seat, providing the lion’s share of those vaccines.”
The roadblocks to vaccines
More than 20,000 primary care clinicians applied to distribute vaccines to patients as of April 2021, according to the Centers for Disease Control and Prevention. A quarter of those received the shots. Fewer than 5% of all vaccine doses were provided to primary care offices during that early stage of rollout.
Natasha Beauvais, MD, MPH, a family physician at Northern Virginia Family Practice in Alexandria, Va., said trying to vaccinate patients back then was a herculean task.
“We were desperate to get the vaccine, like many practices,” Dr. Beauvais said.
It was only by chance – through one of the physician’s work connections – that they got in touch with the city’s health department to request a supply of immunizations.
The requirements for becoming a vaccine provider were stringent: Dr. Beauvais had to show that her practice could appropriately refrigerate or freeze doses at much colder temperatures than most immunizations, monitor the storage unit at all times, and accurately record and schedule every dose. What’s more, most primary care practices lacked the bandwidth to conduct mass vaccinations like larger medical systems.
Robert L. Phillips Jr., MD, MSPH, founding executive director at the American Board of Family Medicine Foundation, said that the decision to sideline primary care practices, along with a poor records system, left clinicians struggling to leverage relationships with patients to boost rates of vaccination.
“Primary care is where most people have trusted health relationships, and it should be more than a footnote in the nation’s epidemic response plans,” said Dr. Phillips, a corresponding author of the Health Affairs study.
The exclusion of primary care has deep roots: These clinicians were mentioned as a footnote in the CDC’s 2017 Pandemic Influenza Plan, according to Dr. Phillips.
“There’s no one in the federal government who wakes up in the morning thinking of primary care,” Dr. Phillips said. “It’s not the only reason the numbers were down, but a big reason.”
Other countries, including Australia, utilized the specialty for vaccine distribution. A 2022 article in Australian Health Review noted that the success of Australia’s COVID-19 vaccine rollout came down to the involvement of primary care.
Dr. Cutler said his clinic also did as much as they could during the early pandemic – from keeping their urgent care clinic open to providing COVID-19 antibody testing and infusions. His practice was able to start vaccinating patients in March 2021, and by that summer, the office had provided the immunization to 4,000 patients. Dr. Cutler was also able to address any health problems these patients reported during their vaccination visit.
“A vaccine is not just a vaccine: It’s an opportunity to have a conversation between a primary care physician and a patient about other health issues, and it encultures people to get important preventive care,” Ms. Greiner said.
The Health Affairs study was supported by the CDC.

It was only by chance – through one of the physician’s work connections – that they got in touch with the city’s health department to request a supply of immunizations.
The requirements for becoming a vaccine provider were stringent: Dr. Beauvais had to show that her practice could appropriately refrigerate or freeze doses at much colder temperatures than most immunizations, monitor the storage unit at all times, and accurately record and schedule every dose. What’s more, most primary care practices lacked the bandwidth to conduct mass vaccinations like larger medical systems.
Robert L. Phillips Jr., MD, MSPH, founding executive director at the American Board of Family Medicine Foundation, said that the decision to sideline primary care practices, along with a poor records system, left clinicians struggling to leverage relationships with patients to boost rates of vaccination.
“Primary care is where most people have trusted health relationships, and it should be more than a footnote in the nation’s epidemic response plans,” said Dr. Phillips, a corresponding author of the Health Affairs study.
The exclusion of primary care has deep roots: These clinicians were mentioned as a footnote in the CDC’s 2017 Pandemic Influenza Plan, according to Dr. Phillips.
“There’s no one in the federal government who wakes up in the morning thinking of primary care,” Dr. Phillips said. “It’s not the only reason the numbers were down, but a big reason.”
Other countries, including Australia, utilized the specialty for vaccine distribution. A 2022 article in Australian Health Review noted that the success of Australia’s COVID-19 vaccine rollout came down to the involvement of primary care.
Dr. Cutler said his clinic also did as much as they could during the early pandemic – from keeping their urgent care clinic open to providing COVID-19 antibody testing and infusions. His practice was able to start vaccinating patients in March 2021, and by that summer, the office had provided the immunization to 4,000 patients. Dr. Cutler was also able to address any health problems these patients reported during their vaccination visit.
“A vaccine is not just a vaccine: It’s an opportunity to have a conversation between a primary care physician and a patient about other health issues, and it encultures people to get important preventive care,” Ms. Greiner said.
The Health Affairs study was supported by the CDC.

With COVID-19 hospitalizations up by 22% and deaths up by 8% as of Aug. 12, primary care clinicians are readying to distribute the new COVID-19 booster that is expected to arrive in September.
David Cutler, MD, is hoping to vaccinate as many of his patients who want the shots. He and other primary care clinicians are finally back in the business of prevention after being sidelined during the pandemic.
Most primary care clinicians weren’t provided with the vaccine through the height of the pandemic, when federal officials instead focused their efforts on vaccine distribution through hospital systems and retail pharmacies. The consequence, primary care clinicians say, is that they have no records for patients who need the vaccine; they cannot send patients reminders; and they have no idea if an at-risk patient is ready for a booster.
“The role of primary care is educating people about COVID-19, testing for COVID-19 and other infections, providing access to vaccines and treatment, and sustaining our health care system to provide care, fight disease, and save lives,” said Dr. Cutler, a family physician at Providence Saint John’s Health Center in Santa Monica, Calif.
A study published in Health Affairs confirmed that primary care practices were not included in the federal vaccine strategy. The researchers found that by the end of 2021, 43.1% of 2,000 primary care practices had no records of COVID-19 vaccinations for patients. More than 90% had records for historically routine immunizations, such as influenza and shingles.
“I do believe if PCPs had earlier access to the vaccine, we could have done a better job vaccinating more people,” said Ann Greiner, MCP, president and chief executive officer of the Primary Care Collaborative, a nonprofit organization. “We need to make sure they’re back in that seat, providing the lion’s share of those vaccines.”
The roadblocks to vaccines
More than 20,000 primary care clinicians applied to distribute vaccines to patients as of April 2021, according to the Centers for Disease Control and Prevention. A quarter of those received the shots. Fewer than 5% of all vaccine doses were provided to primary care offices during that early stage of rollout.

Getting COVID shots in same arm may be more effective, study says
Scientists in Germany looked at health data for 303 people who got the mRNA vaccine and then a booster shot. Their antibody levels were measured two weeks after the second shot. None of the people had had COVID before the vaccinations.
Scientists found that the number of protective “killer T cells” was higher in the 147 study participants who got both shots in the same arm, said the study published in EBioMedicine.
The killer cells were found in 67% of cases in which both shots went into the same arm, compared with 43% of cases with different arms.
“That may suggest that that ipsilateral vaccination (in the same arm) is more likely to provide better protection should the vaccinated person become infected with the SARS-CoV-2 virus,” Laura Ziegler, a doctoral student at Saarland University, Germany, said in a news release.
William Schaffner, MD, a professor in the Division of Infectious Diseases at Vanderbilt University Medical Center, Nashville, Tenn., told CBS News that same-arm vaccinations may work better because the cells that provide the immune response are in local lymph nodes.
There’s greater immunological response if the immune cells in the lymph nodes are restimulated in the same place, said Dr. Schaffner, who was not involved in the German study.
The scientists from Saarland University said more research is needed before they can be certain that having vaccinations in the same arm is actually more effective for COVID shots and sequential vaccinations against diseases such as the flu.

COVID may increase risk of high blood pressure
High blood pressure already impacts about half of U.S. adults, and the study researchers expressed concern about the sheer number of people who have newly developed the condition.
Among people in the study who had COVID but didn’t have a history of high blood pressure:
- One in five who had been hospitalized with COVID developed high blood pressure within 6 months.
- One in 10 who had COVID but were not hospitalized developed high blood pressure within 6 months.
The study appeared in Hypertension, a journal published by the American Heart Association. The researchers analyzed data for more than 45,000 people who had COVID from March 2020 to August 2022. The people did not have a history of high blood pressure. All of them were treated at the Montefiore Health System in New York, and had returned to the hospital system for any medical reason within an average of 6 months.
In an analysis to evaluate the impact of COVID, the researchers compared the likelihood of new high blood pressure in people who had the flu to the people who had COVID. The hospitalized COVID patients were more than twice as likely to get high blood pressure, compared with hospitalized flu patients. People who had COVID but weren’t hospitalized were 1.5 times more likely to get high blood pressure, compared with nonhospitalized flu patients.
People at greatest risk were age 40 or older or men, or had conditions such as chronic obstructive pulmonary disease (COPD), coronary artery disease, and chronic kidney disease.
The authors noted that the people in the study mostly lived in a low socioeconomic area, which can be a risk factor for high blood pressure. Aspects of the pandemic other than the virus itself could have impacted high blood pressure risk, too, like isolation, low activity levels, poor diet, and psychological stress. The researchers said further study is needed to overcome limitations of their research, in particular that it only included people who interacted with the health care system, and that they didn’t know if some people already had high blood pressure that was just undiagnosed.
“Given the sheer number of people affected by COVID-19, compared to influenza, these statistics are alarming and suggest that many more patients will likely develop high blood pressure in the future, which may present a major public health burden,” researcher Tim Q. Duong, PhD, professor of radiology at Albert Einstein College of Medicine and Montefiore Health System, New York, said in a statement. “These findings should heighten awareness to screen at-risk patients for hypertension after COVID-19 illness to enable earlier identification and treatment for hypertension-related complications, such as cardiovascular and kidney disease.”

CDC tracking new COVID strain
On Aug. 17, the agency posted on X, formerly known as Twitter, that the lineage has been detected in the United States, Denmark, and Israel.
“As we learn more about BA.2.86, CDC’s advice on protecting yourself from COVID-19 remains the same,” the CDC said on X.
A case of BA.2.86 was detected at a laboratory at the University of Michigan, CBS News reported. It’s not clear how the university obtained the sample that was sequenced. A case was also detected in the United Kingdom, the news outlet said.
The World Health Organization is also tracking BA.2.86 and has classified it as a “variant under monitoring.”
“More data are needed to understand this COVID-19 variant and the extent of its spread, but the number of mutations warrants attention. WHO will update countries and the public as we learn more,” the WHO said on X.
The strain is so new that scientists don’t know if BA.2.86 is more easily spread, causes more severe symptoms than existing strains, or will be more resistant to vaccines and natural immunity developed over the last few years.
Early research indicates BA.2.86 “will have equal or greater escape than XBB.1.5 from antibodies elicited by pre-Omicron and first-generation Omicron variants,” Jesse Bloom, PhD, a virologist at the Fred Hutchinson Cancer Center, said in a slide deck published Aug. 17. (XBB.1.5 is the Omicron subvariant that is targeted in the updated COVID booster shot to be released soon.)
Still, Dr. Bloom noted that “even if a highly mutated new variant like BA.2.86 starts to spread, we will be in a far better place than we were in 2020 and 2021, since most people have some immunity to SARS-CoV-2 now.”

COVID hospitalizations climb for fourth straight week
Weekly new hospitalizations for COVID-19 have climbed for the fourth straight week.
Centers for Disease Control and Prevention figures. Hospitalizations reached an all-time low of about 6,300 per week in July.
The CDC stopped tracking the number of people infected by the virus earlier in 2023, and now relies on hospitalization data to gauge the current impact of COVID-19.
“We have to remember that we’re still dealing with numbers that are far less than what we’ve seen for the pandemic,” John Brownstein, PhD, a professor of biomedical informatics at Harvard Medical School, Boston, told ABC News. “We have to zoom out to look at our experience for the entire pandemic, to understand that what we’re dealing with now is far from any crisis that we’ve experienced with previous waves.”
The current predominant strain remains EG.5, and experts believe it is not more severe or more contagious than other recent variants.
Dr. Brownstein told ABC News that one reason for the concern about rising COVID metrics, despite their overall low levels, is that a surge occurred in the summer of 2021 with the dangerous Delta variant.
“But each new variant so far that has come through has subsequently had less of a population impact,” he said. “Now, is it possible we may see one in the future that is worthy, a real concern? Absolutely. But overall, we’ve seen a dampening of effect over the last several variants that have come through.”
