FDA's vaccine advisers meet to decide whether Americans need boosters

FDA vaccine advisers started meeting Friday morning to discuss whether most Americans need to start getting booster doses of coronavirus vaccine.

The all-day meeting will be packed with presentations. They'll include Pfizer/BioNTech, which is arguing that there's enough evidence of waning immunity to justify giving booster doses to people. The FDA will present its own take on the data that's been sent to the agency so far -- although written briefing materials published before the meeting suggest the agency is remaining neutral for the time being.
