FDA vaccine chief Dr. Peter Marks said it wouldn’t be surprising if the agency authorized another booster dose in the fall.
President Joe Biden receives his second COVID-19 booster shot March 30 in the South Court Auditorium on the White House campus.While many Americans are trying to move on with their lives after two years of the COVID-19 pandemic, U.S. health officials are debating the best way to use vaccines to stay ahead of the coronavirus.
“All that taken together makes us conclude that a general discussion of booster vaccination against COVID-19 is warranted at this time so that we can potentially intervene,” Marks said.How should the U.S. decide when to launch future rounds of booster shots? Who should get them? The last U.S. wave was driven by the omicron variant. During that surge, two doses were nearly 80% effective against needing a ventilator or death — and a booster pushed that protection to 94%, federal scientists have reported. COVID-19 cases have dropped to low levels in the U.S., but health officials are warily watching an omicron sibling that now accounts for most new cases.All the COVID-19 vaccines now used in the U.S. are based on the original coronavirus version that emerged in late 2019.
