The director of the National Institutes of Health (NIH) said the Food and Drug Administration (FDA) could decide in the coming weeks whether to authorize COVID-19 vaccine booster shots to more Americans in the fall.
Dr. Francis Collins told “Fox News Sunday” that FDA officials are reviewing US COVID-19 cases and vaccines “almost daily,” determining that no decision has yet been made.
There have been a number of studies that have found that the efficacy of Pfizer and Moderna shots that use mRNA technology has decreased in recent months.
While Collins stressed that vaccinated individuals remain highly protected from the virus, he said there are concerns that vaccines are not as effective as previously thought. If that scenario is indeed the case, Collins said it may require a booster shot “starting first with health care providers as well as people in nursing homes, and then gradually progressing to “, such as in high-risk populations such as elderly Americans.
He said more data about the COVID-19 delta variant will help the FDA and other health agencies decide on booster shots in the “next few weeks.”
The FDA has not fully authorized any vaccines made by Johnson & Johnson, Moderna or Pfizer. The vaccines have been administered through the agency’s Emergency Use Authorization, although some federal health officials anticipate that the shots will be fully approved in the coming weeks.
Late last week, a US Centers for Disease Control and Prevention (CDC) advisory panel voted to authorize a third vaccine dose for immunocompromised individuals.
“I signed the recommendation of the CDC’s Advisory Committee on Immunization Practices (ACIP) to recommend an addition of a COVID-19 vaccine to people with moderate to severely compromised immune systems after an initial two-dose vaccine series. supplements,” Valensky, CDC head, said in a statement last week.
The CDC’s decision affects less than 3 percent of the US population and includes people with HIV, cancer patients, transplant patients, and others.
Amid the agency’s decision, other officials insisted that other individuals should not receive a third shot.
“Fully vaccinated non-immunized people are adequately protected and do not require additional doses of the COVID-19 vaccine at this time,” FDA Acting Commissioner Dr. Janet Woodcock said in a statement on August 12. We are engaged in a science-based, rigorous process with our federal partners to consider whether an additional dose may be needed in the future.”
Neither Collins, COVID-19 advisor Anthony Fauci, nor CDC director Rochelle Valensky have made many public comments about individuals who have recovered from COVID-19 and have natural immunity, saying instead There have been reports that COVID-19 vaccines provide better protection.
a study continues Emory University last month, however, said that recovered COVID-19 patients “maintain broad and effective long-term immunity to the disease” and “that there are additional unknown factors influencing age-related differences in COVID-19 responses.” “
