A two-strain vaccine will better protect against fast-moving virus, says an FDA panel.
Troubled by waning immune protection against the COVID virus, this fall’s vaccine booster should be a redesigned two-strain version, according to a recommendation by the FDA’s panel of experts on Tuesday.
Public health experts are braced for a larger surge in cases this fall and winter, as people head indoors. Between 95,000 and 211,000 people could die of COVID between March 2022 and March 2023, Lessler said. Doses of modified vaccine could cost the federal government about $5 billion to $12 billion, one senior federal official told The New York Times.
Offit expressed concern about the speed of the shift, based on relatively small clinical studies. “I think as a new product it should be handled as a new product,” he said. “I think we need a higher standard than what we’ve been given. I think it’s uncomfortably scant.”
