The American Academy of Pediatrics (AAP) has released findings that offer no new evidence to support recent changes in guidance regarding the hepatitis B (Hep B) vaccine for newborns. A study published in Pediatrics challenges recommendations issued last year by the Centers for Disease Control and Prevention’s (CDC) Advisory Committee on Immunization Practices (ACIP) that suggested discouraging the birth dose of the vaccine for infants born to mothers who test negative for hepatitis B.
The debate centers on the initial dose of the Hep B vaccine, traditionally administered within 24 hours of birth. The ACIP’s revised guidance, adopted in August 2025, stemmed from concerns about potential overvaccination and a desire to align with international practices. Still, the AAP’s analysis indicates that altering this long-standing protocol isn’t currently warranted, raising questions about the basis for the shift in recommendations.
Hepatitis B is a viral infection that attacks the liver and can cause both acute and chronic disease. According to the CDC, an estimated 2,200 people die each year from liver disease related to hepatitis B infection . The birth dose of the Hep B vaccine has been a cornerstone of preventing mother-to-child transmission of the virus, particularly in regions with higher prevalence rates.
Study Findings and ACIP Recommendations
The AAP study meticulously reviewed available data on the safety and efficacy of the birth dose Hep B vaccine. Researchers found no compelling evidence to suggest that delaying or omitting the initial dose provides any significant benefit and potentially introduces risks. The study specifically examined the impact on infants born to mothers who tested negative for the hepatitis B surface antigen (HBsAg).
The ACIP’s June 2025 recommendations, which were adopted by the CDC Director on August 4, 2025, proposed that infants younger than 8 months born during or entering their first respiratory syncytial virus (RSV) season, and who are not protected by maternal vaccination, receive one dose of clesrovimab. The committee also stated there was no preferential recommendation between nirsevimab and clesrovimab . However, the AAP’s new findings specifically address the Hep B vaccine and do not directly relate to the RSV recommendations.
Implications for Immunization Schedules
The AAP’s findings are likely to fuel further discussion among healthcare professionals regarding the optimal Hep B vaccination schedule. The current recommended childhood and adolescent immunization schedule, published by the AAP, is revised annually to reflect the latest vaccine recommendations . The organization’s stance could influence future updates to these schedules.
Healthcare professionals can access all CDC recommended immunization schedules through the CDC Vaccine Schedules app, optimized for tablets and smartphones . These schedules guide providers in determining the appropriate vaccines for each age group, taking into account factors such as medical conditions and risk factors.
What’s Next in Vaccine Guidance?
The ongoing evaluation of vaccine recommendations highlights the dynamic nature of public health policy. The ACIP regularly meets to review new scientific evidence and adjust guidelines accordingly. The next ACIP meeting will be crucial in determining whether the committee will revisit its recommendations regarding the Hep B birth dose in light of the AAP’s study. Continued monitoring of hepatitis B incidence rates and vaccine effectiveness will also be essential in shaping future guidance.
