One hundred days after resigning from the Centers for Disease Control and Prevention (CDC), former chief medical officer Dr. [Name Redacted] has issued a stark warning about the erosion of scientific integrity and the destabilization of the nation’s public-health infrastructure. The resignation in late August, alongside two colleagues, came amid concerns over leadership under Secretary of Health and Human Services Robert F. Kennedy Jr.
The departures followed a series of controversial actions, including the dismissal of members of the Advisory Committee on Immunization Practices (ACIP), changes to CDC guidance communicated via social media, and promotion of unproven medications during a measles outbreak. Former CDC director Susan Monarez testified at a Senate HELP Committee hearing in September that she was pressured to rubber-stamp vaccine recommendations and marginalize senior career scientists.
Despite initial public attention, Dr. [Redacted] says conditions have worsened. Since September, the CDC has onboarded at least two additional political hires, bringing the total to 14 political leaders in the Office of the Director, with no career scientists in those roles. Acting CDC Director Jim O’Neill has neither a scientific nor medical background, and some new hires have previously made anti-vaccine statements.
Staff terminations—including those working on Ebola and measles responses—have continued, while the CDC website has shifted to emphasize political positions on topics such as immigration, abortion, and gender ideology, according to Dr. [Redacted]. Updates to pages on mpox and autism misrepresent scientific guidance, prompting some state health departments to remove CDC links from their websites.
In November, senior leadership rolled out 16 strategic initiatives developed by political appointees without scientific review, including priorities such as “enhancing scientific rigor” led by an aviation attorney and a realtor with no public-health credentials. At this week’s ACIP meeting, presenters on the hepatitis B vaccine included individuals not recognized as vaccine scientists, and an anti-vaccine attorney was given a platform to discuss the childhood immunization schedule.
The impact is already visible in U.S. hospitals. Dr. [Redacted] reported pediatric deaths from vaccine-preventable diseases, including whooping cough, and ongoing measles outbreaks linked to delayed guidance and reduced messaging on vaccine safety.
“The nation’s public-health infrastructure is destabilized,” the former official said. “These are failures of federal leadership, not clinicians or health departments. The stakes for children, communities, and pandemic preparedness are too high to remain silent.”
Dr. [Redacted] called on Congress, governors, health systems, and scientific organizations to take immediate action, including oversight, pressure, and protection for career staff. “This is not reform. It is the hollowing out of an institution Americans rely on in every emergency,” they said.
