Senate Confirms Susan Monarez as CDC Director Amid Agency Restructuring

In a significant development for public health leadership, the U.S. Senate has confirmed Susan Monarez, Ph.D., as the new director of the Centers for Disease Control and Prevention (CDC). The confirmation, which passed along party lines with a 51-47 vote, marks a historic moment as Monarez becomes the first CDC director to be confirmed by the Senate under the CDC Leadership Accountability Act of 2023.

A Non-Medical Director Takes the Helm

Monarez's appointment is notable for several reasons. She will be the first person without a medical degree to lead the CDC in over 70 years, bringing instead a Ph.D. in microbiology and immunology from the University of Wisconsin. Her background includes a long career in government service, with previous roles at the Advanced Research Projects Agency for Health and the White House Office of Science and Technology Policy.

During her confirmation hearing, Monarez addressed key public health issues, stating, "I think vaccines save lives," and committing to prioritize vaccine availability. When questioned about the controversial claim linking vaccines to autism, Monarez firmly responded, "I have not seen a causal link between vaccines and autism."

CDC Faces Significant Changes and Challenges

Monarez assumes leadership of the CDC at a time of substantial upheaval for the agency. Recent months have seen steep budget and staffing cuts, with the Department of Health and Human Services (HHS) proposing a $1.2 billion reduction in the CDC's program-level budget for the 2026 fiscal year.

Perhaps the most contentious change has been HHS Secretary Robert F. Kennedy Jr.'s decision to remove all 17 members of the Advisory Committee on Immunization Practices in June. This move has sparked criticism from the American Medical Association and prompted an investigation by Democratic lawmakers.

Balancing Act: Public Health Priorities and Administration Policies

As the new CDC director, Monarez faces the challenge of balancing established public health priorities with the controversial policy stances of the current administration. She has committed to presenting science and facts to guide decision-making while supporting the administration's broader Make America Healthy Again (MAHA) vision.

Monarez also expressed her intention to address the agency's credibility issues with the general public, a task that may prove difficult given the recent restructuring and policy changes at the CDC.
