Dr. Peter Marks, the Food and Drug Administration’s top vaccine regulator, has resigned, an official at the Department of Health and Human Services said Friday.

“If Peter Marks does not want to get behind restoring science to its golden standard and promoting radical transparency, then he has no place at FDA under the strong leadership of Secretary Kennedy,” a spokesperson at HHS said.

A person familiar with the matter told NBC News that Marks was forced out of his position.
