CDC Director Susan Monarez has been removed from her role just one month into her tenure, according to an announcement from the Department of Health and Human Services (HHS). The decision comes amid internal tensions over policy changes related to the COVID vaccine, with HHS Secretary Robert F. Kennedy Jr. reportedly pressuring Monarez to resign multiple times.

Monarez, confirmed by the Senate earlier this month, was called into a meeting with RFK Jr. and HHS officials on Monday, where she was urged to step down. She refused, leading to her removal. The agency stated in a post that “Susan Monarez is no longer director” but did not provide an explicit reason for her ouster. An anonymous HHS official cited pressure from the White House for her resignation, though Monarez reportedly declined and remained in her position.

Several top CDC officials also resigned following the announcement, including Chief Medical Officer Debra Houry and directors of key divisions. The moves coincided with RFK Jr.’s decision to revoke the Emergency Use Authorization for the COVID vaccine, a policy shift that has raised questions about access and eligibility. Under the new guidelines, individuals seeking vaccination would need approval from a healthcare provider before receiving doses, adding an additional step to the process.

Monarez, who had previously faced criticism for her pro-vaccine stance, was seen by some as a counterbalance to RFK Jr.’s agenda. Her removal has sparked speculation about broader changes within the agency, though HHS has not detailed the motivations behind the leadership overhaul. The White House did not immediately comment on the developments.
