Marks wrote in his letter that he was “willing to work” with Kennedy on allaying concerns the HHS secretary holds about vaccines. However, he ultimately concluded that “truth and transparency are not desired by the Secretary, but rather he wishes subservient confirmation of his misinformation and lies.”

According to a former FDA official who spoke to the AP on condition of anonymity, Marks had been given the option to resign or be fired by Kennedy.
Kennedy’s recent record on vaccines
Despite building a career out of questioning the safety and efficacy of vaccines, Kennedy said during his Senate confirmation hearing that he would adhere to longstanding government recommendations guiding vaccine use.
More recently, amid an ongoing measles outbreak that has spread to four states and sickened more than 370 people, Kennedy did tout the importance of vaccines in a Fox News opinion piece. However, he stopped short of fully endorsing them and stressed that vaccines are a personal choice.
“Vaccines not only protect children from measles, but also contribute to community immunity, protecting those who are unable to be vaccinated due to medical reasons,” Kennedy wrote, adding that “the decision to vaccinate is a personal one” and “good nutrition remains a best defense against most chronic and infectious illnesses.”
Meanwhile, the Centers for Disease Control and Prevention, which falls under Kennedy’s HHS, announced plans to study a potential link between vaccines and autism –– a link that has been roundly debunked by a majority of the scientific community.
Kennedy’s messaging on measles wasn’t enough to convince Marks, as the top vaccine official wrote in his letter that “efforts currently being advanced by some on the adverse health effects of vaccination are concerning.” He also raised concerns about the “unprecedented assault on scientific truth that has adversely impacted public health in our nation.”
HHS did not respond to the AP’s request for comment. Marks could not be reached for comment.
Dr. Marks and ‘Operation Warp Speed’
Marks served during Donald Trump’s first presidency and helped guide the administration’s “Operation Warp Speed,” an expedited rollout of vaccines during the COVID-19 pandemic. According to the AP, Marks is credited with coining the initiative’s name and concept.
