Fifth COVID-19 Vaccine Shot May Be Needed In Fall: FDA Official

Hours after the Food and Drug Administration (FDA) authorized a fourth shot of the Moderna and Pfizer COVID-19 vaccines for all Americans 50 and older, an FDA official said a fifth shot may be needed in the fall.

“I don’t want to shock anyone but there may be a need for people to get an additional booster in the fall, along with a more general booster campaign if that takes place, because we may need to shift over to a different variant coverage,” Dr. Peter Marks, head of the FDA center that regulates vaccines, told reporters on a call on March 29.

The fresh emergency use authorization is for a fourth shot for Americans 50 and up and a fifth shot for people as young as 12 with weakened immune systems. The boosters from Moderna and Pfizer target the strain of SARS-CoV-2, or the CCP (Chinese Communist Party) virus, that was circulating in early 2021. Multiple strains have since emerged and become dominant in the United States. Omicron is the latest.

Moderna and Pfizer are testing vaccine formulations that specifically target Omicron.

“It may be that a decision is made that rather than what we currently have, the vaccines we currently have—which are called vaccines against the prototype virus—that we will move to a vaccine that is either against one of the variants—whether it’s Omicron, Beta, or Delta, or something else, I can’t say right now that’s for discussion—or whether it’s some mix of different ones,” Marks said. “But it’s possible that people will need to get another vaccine.” – READ MORE
