The Trump administration confirmed it fired CDC Director Susan Monarez after she refused to resign following a dispute with Health Secretary Robert F. Kennedy Jr. over vaccine policy. This escalation also led to the resignation of five other senior officials from the Centers for Disease Control and Prevention (CDC).

• Susan Monarez was CDC head for less than a month before her dismissal.
• The dispute centered on Health Secretary Robert F. Kennedy Jr.'s sweeping overhaul of US vaccine policy.
• Five senior officials, including Demetre Daskalakis, Debra Houry, and Daniel Jernigan, resigned from the CDC in protest.
