In February 2025, the regular meeting of the Advisory Committee on Immunization Practices (ACIP) was abruptly adjourned shortly after the confirmation of Robert F. Kennedy Jr. as Secretary of HHS.[1][3] The CDC updated the vaccination schedules for adults and children, introducing individual decision-making for COVID-19 vaccination.[1][2] The ACIP recommended that the COVID-19 vaccine be recommended for persons 6 months and older based on shared decision-making with a physician, with an emphasis on at-risk groups up to 64 years of age.[1][2][4] For varicella (chickenpox), they recommended a stand-alone vaccine instead of a combination vaccine with measles, mumps, and rubella.[1] The ACIP approved changes to hepatitis B vaccination for newborns, proposing to delay the first vaccination for at least one month in children of mothers who test negative, by a vote of 8 to 3.[5][7][8][9][10] These recommendations were approved by the CDC on October 6, 2025, and the schedules will be updated by October 7, 2025.[1][2] Only 23% of adults have followed through from the previous across-the-board recommendation of COVID boosters.
