The U.S. Food and Drug Administration is poised to clear a fourth dose of the mRNA coronavirus vaccine for adults age 50 and older, looking to shore up protections for more vulnerable groups, a person familiar with the matter said.
The authorization could come as early as next week and, for most Americans, it would mean a second booster shot of either the Pfizer-BioNTech or Moderna vaccines. Currently, only immunocompromised people are eligible in the U.S. for the additional dose.
