The CDC’s Advisory Committee on Immunization Practices (ACIP) began its December 4 and 5, 2025, meeting today, launching two full days of presentations, public comment and planned votes that could reshape how infants and children receive hepatitis B (HepB) vaccines and other routine immunizations.

It marks the third meeting this year of the Advisory Committee on Immunization Practices (ACIP) since Health and Human Services Secretary Robert F. Kennedy Jr. fired all 17 members, replacing them with his own hand-selected picks, many of whom have expressed vaccine-skeptic views.

Vaccine advisers to the US Centers for Disease Control and Prevention may vote this week to make a major change to the childhood vaccine schedule, potentially delaying a dose of the hepatitis B vaccine given to newborns by weeks or even years.

Health officials warn that proposed changes to the hepatitis B vaccine schedule could trigger a resurgence of the disease. Delaying the birth dose to two months may cause thousands of preventable infections,

The federal vaccine panel appointed by Health Secretary Robert F. Kennedy Jr. is likely to decide on Thursday that the shots should be delayed for infants whose mothers test negative for the virus.
