The goal is to simplify vaccination against COVID and perhaps adopt an approach similar to what is used for the flu vaccine, with annual updates to match whatever strain of the virus is circulating.

NPR reported the proposed shift early Monday morning, and later Monday the FDA outlined it publicly in a set of documents released in advance of a meeting Thursday of the agency’s Vaccine and Related Biological Products Advisory Committee (VRBPAC). The committee will vote on the agency’s proposal.

Under the new approach, most people would be advised to simply get whatever the latest version of the vaccine is annually each fall like the flu vaccine. They wouldn’t have to worry about how many shots they’ve already gotten and which one they got when. Those who still need to receive two doses initially, such as young children and older people, would use the same formulation for all three shots.
