FDA vaccine advisers are meeting to consider Moderna Covid-19 vaccine boosters

Vaccine advisers to the US Food and Drug Administration voted unanimously Thursday to recommend emergency use authorization of a booster dose of Moderna's Covid-19 vaccine. The FDA's Vaccines and Related Biological Products Advisory Committee agreed use of a booster dose would be safe and effective in some people six months out from their primary series. But some were clearly reluctant. Moderna had asked for emergency use authorization for a half dose of its vaccine to be used as a booster for certain people.
