U.S. Health and Human Services (HHS) Secretary Robert F. Kennedy, Jr. leaves the stage after discussing the findings of the Centers for Disease Control and Prevention’s (CDC) latest Autism and Developmental Disabilities Monitoring (ADDM) Network survey, at the Department of Health and Human Services in Washington, D.C., U.S., April 16, 2025.

Health and Human Services Secretary Robert F. Kennedy Jr. has gutted a key government panel of vaccine advisors, saying he wants to “re-establish public confidence” in shots.

Some health policy experts say firing the committee members will do the opposite.

“Rather than restoring public trust, his actions are simply politicizing science and vaccine policy,” Lawrence Gostin, professor of public health law at Georgetown University, told CNBC. “I don’t know how it is possible to trust HHS anymore.”

Gostin and other experts said the move undermines science, disrupts a trusted regulatory process for shots and could increase public distrust in both vaccinations and federal health agencies. Some experts said the firings could threaten public health, eroding already falling U.S. immunization rates against once-common childhood diseases and making the nation less equipped to grapple with new or existing outbreaks of vaccine-preventable diseases.

The potential impact on vaccine manufacturers like Moderna , Merck , Pfizer and BioNTech is less clear, but some analysts say it introduces more uncertainty to the regulatory process around shots.

Kennedy, a prominent vaccine skeptic, said Monday he is firing all 17 members of the Advisory Committee on Immunization Practices, or ACIP, which advises the Centers for Disease Control and Prevention. The group of independent medical and public health experts reviews vaccine data and makes crucial recommendations that determine who is eligible for shots and whether insurers should cover them, among other efforts.

It is the latest in a series of steps Kennedy has taken as head of HHS to dismantle decades of U.S. vaccination policy standards and chip away at the public’s confidence in immunizations. Among his most recent efforts, he dropped the CDC’s recommendation for routine Covid-19 vaccines for healthy children and healthy pregnant women, which also sparked outrage in the medical and science community.

While it is unclear who will replace the current panel, some experts warn that Kennedy could try to appoint members who are sympathetic to his anti-vaccine views. That could lead to politicized recommendations that highlight the harms rather than the benefits of shots or make them widely voluntary, deterring more Americans from receiving shots or vaccinating their children, according to some experts.

“It’s really important that we recognize that these actions impact everyone,” Dr. Neil Maniar, a public health professor at Northeastern University, told CNBC. “This is not just a committee that was retired. It is a committee whose work has broad implications.”

HHS did not immediately respond to a request for comment on who will be appointed to the panel, and the concerns from health policy experts.
