vaccines Prasad memo FDA RFK Jr.

A dozen prior leaders of the U.S. Food and Drug Administration issued a scathing denunciation of an FDA memo to staff that made sweeping claims casting doubt on vaccine safety. They said in an editorial published Wednesday in the New England Journal of Medicine that it “will upend core policies governing vaccine development and updates.” The internal memo by vaccine chief Dr. Vinay Prasad claimed without evidence that COVID-19 vaccines caused 10 children’s deaths and proposed changes at the agency. It comes at a time when Health Secretary Robert F. Kennedy Jr. is seeking to broadly remake federal policies on vaccines.
