U.S. would seek global approach to updating Covid-19 vaccines, official says

If the Food and Drug Administration decides to update Covid-19 vaccines to take better aim at Omicron or other variants, it is unlikely to go it alone.

Instead, a senior FDA official told STAT, the agency expects to take part in an internationally coordinated program aimed at deciding if, when, and how to update Covid-19 vaccines. The approach would ensure decisions are not left solely to individual vaccine manufacturers.
