HHS fired biosecurity adviser Steven Hatfill over false claims and vaccine criticism, amid leadership changes under Secretary Robert F. Kennedy Jr.
Steven J. Hatfill, a senior biosecurity adviser at the Department of Health and Human Services, was fired for cause amid controversy over his public criticism of mRNA vaccines, with officials citing false claims that he was chief medical officer and failure to coordinate with leadership.
Hatfill, who joined in spring 2025, had previously promoted hydroxychloroquine and claimed mRNA vaccines cause "biochemical havoc," statements made after HHS announced it would end mRNA vaccine development, including canceling a Moderna contract.
He denied the allegations, alleging a power struggle orchestrated by Secretary Robert F. Kennedy Jr.’s chief of staff.
The firing is part of broader leadership changes at HHS and the CDC under Kennedy’s tenure.
