A European Union advisory committee endorsed extra shots of Pfizer Inc.’s Covid-19 vaccine for all adults, as well as extra doses of Moderna Inc.’s for those with severely weakened immune systems.

Those ages 18 and older can get a third dose of the Pfizer vaccine, developed with BioNTech SE, at least six months after their second shot, the European Medicines Agency said in a statement Monday. For the immunocompromised, extra doses of Pfizer or Moderna can be given at least 28 days after the second.
