Scientist pouring blue liquid into test tube.

FDA’s top vaccine official Dr. Peter Marks has resigned after being allegedly pushed out, accusing HHS Secretary Robert F. Kennedy Jr. of prioritizing misinformation over scientific truth in an escalating battle over vaccine policy.

Quick Takes

  • Dr. Peter Marks, the FDA’s vaccine chief since 2016, will resign effective April 5
  • Marks was reportedly given a choice to resign or be fired by HHS officials
  • His resignation letter directly accused HHS Secretary RFK Jr. of preferring “subservient confirmation” over truth
  • Marks played a crucial role in Operation Warp Speed and COVID-19 vaccine development

FDA Vaccine Official Forced Out Amid Kennedy Administration

Dr. Peter Marks, who has served as the Food and Drug Administration’s top vaccine official since 2016, has resigned from his position after allegedly being given an ultimatum by Health and Human Services (HHS) officials. According to multiple sources, Marks was told to either resign or face termination. His resignation becomes effective on April 5.

The resignation comes amid growing tensions between Marks and newly appointed HHS Secretary Robert F. Kennedy Jr., whose well-documented skepticism about vaccines has been a point of controversy. In his resignation letter addressed to Acting FDA Commissioner Sara Brenner, Marks made his criticisms unambiguously clear about the department’s direction under Kennedy’s leadership.

Conflict Over Vaccine Science and Public Communication

Marks’ departure highlights a fundamental conflict over how vaccine science should be communicated to the American public. Kennedy has claimed to be “pro-safety” rather than “anti-vaccine” however, Marks has been outspoken about the dangers of undermining public confidence in vaccines

An HHS official defended the administration’s stance, suggesting that Marks was not aligned with Kennedy’s vision. “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,” the official stated. This statement suggests fundamental differences in what constitutes scientific transparency between the parties involved.

Broader Implications for Public Health

The timing of this high-profile departure raises concerns among health experts, particularly as the United States faces a measles outbreak across multiple states. This resurgence threatens America’s status of having eliminated the local spread of measles, an achievement reached in 2000 that now hangs in the balance. Marks believes that this outbreak is a direct consequence of undermining public confidence in established science.

The resignation also comes amid reports that HHS is planning to lay off approximately 10,000 workers and potentially shut down certain agencies. Kennedy has publicly criticized the department he now oversees as inefficient and suggested its workers bear some responsibility for the decline in Americans’ health.

The Future of Vaccine Oversight

Former FDA Commissioner Dr. Robert Califf responded to the news by emphasizing the critical importance of evidence-based policies in public health. “I hope this will intensify the communication across academia, industry and government to bolster the importance of science and evidence,” Califf stated. With Marks’ imminent departure, questions remain about who will take over leadership of the FDA’s vaccine division and how this leadership change might affect vaccine approval processes, safety monitoring, and public communication about vaccines..
