Federal Judge Blocks RFK Jr.'s Overhaul of Vaccine Recommendations

A federal judge blocked HHS Secretary Robert F. Kennedy Jr.'s overhaul of routine immunization recommendations, ruling the unprecedented changes to CDC vaccine schedules were "arbitrary and capricious" and violated federal procedure.

A federal judge in Washington on Monday blocked Health and Human Services Secretary Robert F. Kennedy Jr.'s sweeping overhaul of the nation's routine immunization recommendations, ruling the changes were "arbitrary and capricious" and violated federal administrative procedure.

U.S. District Judge Colleen Kollar-Kotelly granted a preliminary injunction halting Kennedy's February 10 memorandum, which stripped the CDC's Advisory Committee on Immunization Practices of its authority to determine routine vaccine schedules and transferred that power to a new HHS-appointed panel. The memo also ordered CDC to remove existing vaccine schedules from its website.

The American Academy of Pediatrics and the American Medical Association sued, arguing the secretary lacked authority to unilaterally dismantle a process established by federal regulation and decades of practice. They also contended the abrupt removal endangered public health by depriving providers and parents of critical information.

Kollar-Kotelly agreed. "The plaintiffs have demonstrated a substantial likelihood that the secretary's actions exceeded his statutory authority and were undertaken without the reasoned explanation required by the Administrative Procedure Act," she wrote. She noted CDC had posted vaccine schedules continuously since 1983 and that "their sudden disappearance from a government website created confusion and uncertainty."

The judge rejected the administration's argument that immediate action was necessary because ACIP members had conflicts of interest, finding no evidence that existing members were improperly influenced.

"This court will not second-guess the secretary's policy preferences," Kollar-Kotelly wrote. "But it will ensure that when the government acts, it does so within the bounds of the law."

HHS said it disagrees with the ruling and is reviewing its options. The ruling allows CDC to restore removed schedules and resume ACIP operations as they existed before Kennedy's memo. In striking down HHS Secretary Kennedy's vaccine overhaul, a federal judge reaffirmed a fundamental principle: even policy driven by conviction must operate within the bounds of law. The Silicon Review considers what this ruling means for the future of public health governance.
