FDA vaccine chief Dr. Peter Marks has resigned from his position amid a clash with Health and Human Services Secretary Robert F. Kennedy Jr., marking a significant turning point in the administration’s approach to public health and vaccine policy.

Top Takeaways

  • Dr. Peter Marks, the FDA’s top vaccine official since 2016, was reportedly given the choice to resign or be fired, with his resignation effective April 5.
  • Marks accused Kennedy of prioritizing misinformation over truth, writing in his resignation letter that “truth and transparency are not desired by the secretary.”
  • The resignation comes as the U.S. faces a measles outbreak that Marks attributes to undermining public confidence in established science.
  • Kennedy, known for his vaccine skepticism, had promised during confirmation hearings not to undermine vaccines but is now overseeing significant changes at HHS.
  • Former FDA officials have expressed concern that Marks’ departure threatens vaccine safety oversight in America.

Conflict Over Science and Truth

Dr. Peter Marks, who has served as the FDA’s vaccine chief since 2016 and played a crucial role in Operation Warp Speed, submitted his resignation letter to Acting FDA Commissioner Sara Brenner. Marks did not mince words about his reasons for leaving, directly challenging Kennedy’s approach to scientific evidence.

According to sources familiar with the situation, Marks was given an ultimatum by HHS officials: resign or be fired. This development aligns with broader changes at the department, where Kennedy has criticized the agencies he oversees as inefficient and is reportedly planning to lay off approximately 10,000 workers. An HHS official defended the action, stating that Marks was not aligned with the department’s new direction under Kennedy’s leadership.

Public Health Concerns

Marks’ departure comes at a crucial time for public health in America. The U.S. is currently experiencing a measles outbreak that has spread to multiple states, something that Marks highlighted as something he believes is a consequence of undermining public confidence in established vaccines.

The timing of the resignation has alarmed many establishment public health experts. Dr. Paul Offit, a vaccine specialist at Children’s Hospital of Philadelphia, expressed serious concerns about the implications of Marks’ departure, suggesting it represents a shift in vaccine safety oversight. Former FDA Commissioner Dr. Robert Califf similarly stressed the importance of maintaining evidence-based policies in public health.

“RFK Jr.’s firing of Peter Marks because he wouldn’t bend a knee to his misinformation campaign now allows the fox to guard the hen house. It’s a sad day for America’s children,” said Offit.

Kennedy’s Stance

Kennedy, who has built a reputation as a vaccine skeptic over many years, has publicly maintained that he is not “anti-vaccine” but rather “pro-safety.” During his Senate confirmation hearings, he promised not to undermine vaccines, stating that his own children are vaccinated and that he believes vaccines play a critical role in healthcare.

An HHS official defended the leadership change, stating: “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.” This statement suggests fundamental differences in what constitutes scientific standards between the Secretary and career officials who have previously overseen vaccine safety and approval processes.

Marks’ resignation, effective April 5, represents a significant shift in FDA leadership during a critical period for public health policy. The departure of such a high-level figure in vaccine regulation signals potential changes in how vaccine safety and efficacy will be evaluated and communicated to the American public going forward.
