The Food and Drug Administration’s top vaccine official submitted his letter of resignation on March 28, citing some of Health Secretary Robert F. Kennedy Jr.’s initiatives.

In a letter to acting FDA Commissioner Sara Brenner, Dr. Peter Marks said that he will step down by April 5 as the head of the Center for Biologics Evaluation and Research, which handles regulating vaccines for the agency. It also oversees allergenic products, blood products, as well as cellular, tissue, and gene therapies.
