The director of the Centers for Disease Control and Prevention (CDC) said an annual COVID-19 booster shot isn’t anticipated, suggesting that a third dose may adequately strengthen the long-term protection of the Pfizer or Moderna vaccines.
When asked about the need for annual booster doses, Dr. Rochelle Walensky said, “I don’t want to say never, but we are not necessarily anticipating that you will need this annually.”
On Aug. 18, Walensky and other federal health agency chiefs said during a joint news conference that they will recommend boosters to individuals eight months after receiving their second COVID-19 mRNA vaccine dose, starting Sept. 20. The CDC and Food and Drug Administration (FDA) haven’t authorized the doses yet.
“We’ve also been in collaboration and discussions with our international colleagues and they are starting to see ... presentation of worsening infection in the context of their breakthroughs,” she said.
Inside the United States, some experts questioned the CDC’s data.
“The message I got from reading all three [studies] was that there may be some reduction in infection protection with Delta in nursing homes, but no data about waning protection from severe disease or hospitalization,” Dr. Walid Gellad, professor of medicine at the University of Pittsburgh’s School of Medicine, wrote on Twitter.
The recent U.S. proposals to provide booster shots now have been flagged by some health experts as unethical and premature. The World Health Organization (WHO) went on the offensive this week, saying that wealthier nations such as the United States should prioritize donating vaccines to poorer nations.
Meanwhile, U.S. Rep. Thomas Massie (R-Ky.) tweeted that the FDA and CDC are misleading the public.
“Just last month, CDC & FDA said no booster needed. At the time, they worried that the truth about long term vaccine efficacy would cause ‘vaccine hesitancy,’” the Kentucky Republican wrote. “They ignored widely available data and drug manufacturers, because both indicated efficacy had dropped significantly.”
President Joe Biden in an ABC News interview aired on Aug. 19 said that both he and First Lady Jill Biden will get booster shots.
“It’s something that I think, you know, because we got our shots all the way back in, I think, December, so it’s past time,” Biden told ABC’s George Stephanopoulos. “Yes, we will get the booster shots.”
