HHS withdraws ACIP charter renewal after administrative error, Reuters reports

HHS withdrew an April renewal of the CDC’s Advisory Committee on Immunization Practices charter after what Reuters described as an administrative error and a missed federal timing requirement.

The withdrawal affects the charter that governs ACIP, the federal vaccine advisory panel that reviews and recommends immunization policy for the CDC. The CDC’s ACIP charter page says the committee operates under a filed charter and that renewals determine whether it continues.

Reuters reported the move on May 18, 2026, citing HHS’s explanation that the agency missed a required filing window. Bloomberg Law reported a similar account earlier the same day.

The April 6 renewal had been reflected on the CDC charter page dated April 8. HHS had also reconstituted ACIP in June 2025 as part of broader vaccine-policy changes.

It was not immediately clear whether HHS plans to reissue the renewal, restore the April filing, or whether the withdrawal changes only the filing timeline rather than ACIP’s membership rules.

What happens next

The immediate question is whether HHS will publish further legal notice or take another action to keep the charter in force. For now, the episode highlights how a procedural error can affect the status of a federal advisory committee that sits at the center of vaccine guidance.
