# Top FDA vaccine regulator Peter Marks resigns, citing pressure to confirm vaccine 'misinformation'

Date: 2025

On March 28, 2025, Dr. Peter Marks, director of the FDA's Center for Biologics Evaluation and Research (CBER) and a central figure in the COVID-19 vaccine authorizations (he is credited with originating the name 'Operation Warp Speed'), announced his resignation effective April 5, 2025. In his resignation letter he wrote that he had been willing to address the Health Secretary's vaccine-safety concerns through public meetings and engagement with the National Academy of Sciences, but that 'it has become clear that truth and transparency are not desired by the Secretary, but rather he wishes subservient confirmation of his misinformation and lies.' Reporting indicated he had been given the choice to resign or be removed.
