Everyone eligible for a first booster who hasn’t gotten one yet needs to, FDA vaccine chief Dr. Peter Marks said. But the second booster is only for these higher-risk groups because “current evidence suggests some waning of protection” for them.
The Food and Drug Administration’s decision opens a fourth dose of the Pfizer or Moderna vaccines to that age group at least four months after their previous booster.
Until now, the FDA had cleared fourth doses only for people 12 and older who have severely weakened immune systems. The agency said this especially fragile group also can get an additional booster, a fifth shot.
The latest expansion, regardless of people’s health, allows an extra shot to millions more Americans — and the question is whether everyone who’s eligible should rush out and get it. The Centers for Disease Control and Prevention is expected to weigh in.
