Trump appoints Susan Monarez as the head of the Centers for Disease Control and Prevention (CDC)

The U.S. Centers for Disease Control and Prevention (CDC), the nation's leading public health institution, has a new director in Susan Monarez. Confirmed in July 2025, Monarez brings a wealth of experience in health technology, biosecurity, and microbiology to the role.

Based in Atlanta, the CDC is responsible for tracking diseases and responding to health threats. Monarez, who holds a doctorate in microbiology and immunology from the University of Wisconsin, has a solid academic background to tackle these challenges. She did her postdoctoral research at Stanford University before embarking on a career in government.

Prior to her role at the CDC, Monarez was known for her government roles in health technology and biosecurity. In January, she was named acting director, and in March, she was tapped as the nominee for the position. Her confirmation hearing did not provide clarity on her stance regarding Health Secretary Robert F. Kennedy Jr., an outspoken antivaccine activist who has been involved in upending long-standing CDC vaccine policies.

Monarez publicly supports vaccines and rigorous scientific evidence. During her confirmation hearing, she emphasized that vaccines save lives and stated she had not seen a causal link between vaccines and autism, distancing herself from conspiracy theories. However, she largely avoided detailed answers about her dealings with Kennedy.

Kennedy has sought to dismantle some of the CDC's previous protocols and decisions. The CDC has faced controversy over its vaccine policies, and the agency has experienced widespread staff cuts. Kennedy's policies have also led to key resignations.

Experts and former CDC leaders have expressed concern that Monarez must protect the agency amid political pressures and structural challenges. Monarez has affirmed support for other public health measures like fluoride in tap water, even as Kennedy's directives have pushed some changes there as well.

In summary, Monarez maintains a pro-vaccine stance and commitment to science but has tempered public statements about her relationship with Kennedy. She appears tasked with navigating significant political and institutional tensions within the agency.

Monarez became the first CDC director to pass her Senate confirmation under a 2023 law. Her appointment comes at a critical time for the CDC, as it grapples with ongoing health threats and political pressures.
