HHS yanked its revised charter for the CDC's Advisory Committee on Immunization Practices (ACIP) little more than a month after the agency unveiled changes that critics warned would keep vaccine-skeptical policies and members driving the panel.

HHS withdrew the charter "due to an administrative error in meeting the revised public notification timing requirements," according to a Federal Register notice. "As a result, the charter lapsed and the committee must be re-established."
