Chaos at the CDC: A New Direction Sparks Concern

Former top CDC leader Dr. Debra Houry—who resigned in protest last summer—claims that under Health and Human Services Secretary Robert F. Kennedy Jr., the agency has plunged into a state of “pure chaos.”
Her accusations focus on several alarming developments:

• ACIP Overhaul – On June 9, 2025 all 17 members of the Advisory Committee for Immunization Practices (ACIP) were removed. New advisers, many with little or no medical or scientific training, were swiftly appointed.
• Flawed Vaccine Schedules – The new panel altered vaccine schedules: thimerosal was removed from flu shots, and the universal birth dose of Hepatitis B was eliminated—decisions already challenged in federal court.
• Undermined Trust – Kennedy has refused briefings on the measles outbreak and spread misinformation about vaccines, eroding public confidence.
• Conflict of Interest – Kennedy previously profited from lawsuits against vaccine manufacturers. He dismissed the ACIP as a “rubber stamp,” replacing it with allies who share his agenda rather than evidence‑based experts. The new panel lacks proper conflict‑of‑interest checks and bypassed the Freedom of Information Act process.

Fallout

• State Divergence – Twenty‑nine states and Washington, D.C. no longer follow CDC childhood vaccination schedules.
• Judicial Intervention – A federal judge has halted most of the new panel’s appointments and any changes they made to vaccine recommendations.
• Political Scrutiny – Senate Health Committee Chair Dr. Bill Cassidy has called for an investigation, and the American Academy of Pediatrics joined lawsuits against the agency’s new direction.

Historical Context

Houry recalls how, during President Trump’s second term, the CDC was forced to remove pages about gender from its website due to an executive order—illustrating how political interference hampers accurate medical guidance. When Kennedy attempted to link autism to vaccines, Houry labeled the approach “conspiracy‑lensing” and urged broader, evidence‑based research rather than a narrow focus on vaccination data.

Conclusion

Houry believes the CDC’s credibility has been irreparably damaged and that restoring public faith will be a long, difficult journey. She resigned because she could no longer safeguard the scientific integrity of the agency.
