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.

A panel of U.S. vaccine experts was meeting Wednesday to discuss key questions for future COVID-19 booster campaigns. The Food and Drug Administration’s vaccine advisers won’t make any binding decisions during the virtual meeting, but their advice could shape the government’s approach for years to come.

FDA vaccine chief Dr. Peter Marks told reporters last week that it wouldn’t be surprising if the agency authorized another booster dose in the fall to protect most Americans against the latest coronavirus mutations. He opened Wednesday’s meeting by cautioning that waning vaccine protection, new variants and colder weather later this year could raise the risk of more surges.
