FDA advisers recommend updating COVID booster shots for fall
Associated PressAt least some U.S. adults may get updated COVID-19 shots this fall, as government advisers voted Tuesday that it’s time to tweak booster doses to better match the most recent virus variants. Their combination shots, what scientists call “bivalent” vaccines, substantially boosted levels of antibodies capable of fighting that variant, more than simply giving another dose of today’s vaccine. Marks said that by tweaking the shots, “we’re hoping we can convince people to go get that booster to strengthen their immune response and help prevent another wave.” The logistics will be challenging. Advisers to the World Health Organization recently said omicron-tweaked shots would be most beneficial as a booster only, because they should increase the breadth of people’s cross-protection against multiple variants.
