FDA says those 50 and older may get a second Pfizer or Moderna COVID-19 vaccine booster dose four months after their first booster of any brand.
The FDA said Tuesday that people age 50 and older may get a second Pfizer or Moderna COVID-19 booster shot four months after their first as the highly contagious omicron subvariant BA.2 was reported to account for more than half of U.S. cases.
“Based on an analysis of emerging data, a second booster dose of either the Pfizer-BioNTech or Moderna COVID-19 vaccine could help increase protection levels for these higher-risk individuals,” Marks continued. “Additionally, the data show that an initial booster dose is critical in helping to protect all adults from the potentially severe outcomes of COVID-19. So, those who have not received their initial booster dose are strongly encouraged to do so.
“There is no greater slap in the face of science than bypassing the customary FDA external expert voting process over an authorization with insufficient supporting clinical data,” Dr. Marty Makary, a professor at Johns Hopkins University, said in a series of tweets Tuesday morning. “It’s like a judge issuing a verdict and then having lawyers make their arguments.”
