The US Food and Drug Administration’s (FDA) top vaccine regulator, Peter Marks, has abruptly resigned from his post as director of the Center for Biologics Evaluation and Research (CBER), reportedly having been “forced out.”

In his resignation letter, Marks made it clear that he did not leave willingly. He blamed the newly minted Health Secretary, Robert F. Kennedy Jr, for his exit.
