In August 2025, Demetre Daskalakis, the leading immunization officer at the Centers for Disease Control and Prevention (CDC), submitted his resignation. Frustrated by the deteriorating state of the national vaccine system, he made this decisive move. That evening, Daskalakis visited his office on the eighth floor of the CDC to gather memorabilia from his long career in public health.
The decision to resign came as a protest against Health Secretary Robert F. Kennedy Jr. Daskalakis, following his resignation, became one of Kennedy’s most vocal critics, highlighting the system’s shortcomings and advocating for improvements.
Throughout his tenure, Daskalakis had been a prominent figure in the battle for public health, making significant contributions to immunization efforts nationwide. His departure underscored the challenges facing the public health sector amidst rising concerns about vaccination policies.
