Bivalent COVID-19 shot should become standard, FDA advisers say
Bivalent COVID-19 shots should become the standard form of the vaccine, U.S. advisers said, part of a plan to offer a single booster to the public each year that gives protection against the most recent, dominant strains.
Anyone getting a COVID-19 shot for the first time now receives a vaccine designed in 2020, when the virus looked a lot different than it does today. A panel of 21 advisers to the Food and Drug Administration voted unanimously Thursday to make bivalent vaccines, designed to fight the BA.4 and BA.5 omicron strains, the primary option.
