That move drew criticism because it leaped ahead of decisions by scientific agencies and triggered a fierce debate about whether those extra shots were warranted now, and for whom.

The authorizations mean eligible people initially vaccinated with those shots can get a booster of the same — but may also switch. That means someone who received the Johnson & Johnson product can get a booster dose with Moderna or Pfizer-BioNTech, as long as the person is 18 or older, meeting the criteria to get a booster. And someone who has been fully vaccinated with Moderna can get a booster with Johnson & Johnson or Pfizer, if they are 65 or older, or at high risk.

The FDA did not recommend any particular combination of vaccines and boosters — or even whether it would be better to stick with the original vaccine or switch to a different one. In a call with reporters, top agency officials said they did not have the data to make those specific judgments.
