The Food and Drug Administration is considering shifting to an annual process for updating COVID-19 vaccines to match circulating coronavirus strains, akin to the current approach for influenza.
The proposal from agency staff, released Monday ahead of a Thursday meeting of FDA advisers, envisions most people receiving one dose each fall of a COVID vaccine that has been tailored to the most prevalent virus variants. People who are likely to have insufficient preexisting immunity, such as older adults, very young children and the immunocompromised, would get two shots.
