In a recent decision made on December 5, 2025, the Centers for Disease Control and Prevention (CDC) held a significant vote regarding vaccine recommendations for newborns in the United States. The Advisory Committee on Immunization Practices (ACIP) decided by a vote of 8-3 to remove the long-standing universal recommendation for administering the hepatitis B vaccine at birth. This change is rooted in an updated approach that emphasizes evaluating vaccination based on maternal testing status rather than a blanket policy for all newborns. The revised recommendations indicate that if a mother tests negative for hepatitis B, parents should consult with their healthcare provider to discuss whether the vaccination is appropriate for their newborn. This individual-based decision-making reflects a shift in strategy that allows parents more agency in determining the healthcare choices for their children. The ACIP's vote also established that infants who do not receive the initial hepatitis B shot at birth must receive a first dose no sooner than 2 months old. Importantly, the committee's decision does not alter the guidance that infants born to mothers who test positive for the virus or whose status is unknown should still be vaccinated to protect their health. The decision was made with consideration of whether the newborn may face risks, such as living with someone who is hepatitis B-positive or having close contact with individuals from areas where the virus is endemic. In an additional vote, the ACIP suggested that parents of older children engage in discussions with their healthcare providers about hepatitis B antibody testing before considering further vaccinations. This testing aims to determine if the child has achieved the necessary antibody threshold and is expected to be covered by insurance. The acting director of the CDC, Jim O’Neill, is anticipated to approve this proposed change in recommendations, marking a significant evolution in how hepatitis B vaccinations are approached for infants and children in the U.S. As the situation develops, more updates will be provided to ensure the public remains informed.
