In a significant change to longstanding public health policy, the Centers for Disease Control and Prevention’s (CDC) advisory panel has narrowed its recommendations for hepatitis B vaccination in newborns. For over three decades, the CDC advised universal vaccination within 24 hours of birth. The recent vote by the Advisory Committee on Immunization Practices (ACIP) now suggests vaccination only for infants born to mothers with hepatitis B or whose status is unknown, leaving the decision for other newborns to a discussion between parents and their physicians.
This shift, finalized in December 2025, has sparked concern among public health experts who point to the remarkable success of the universal vaccination program in drastically reducing hepatitis B infections. Between 1990 and 2019, acute infections among children and teens plummeted by 99%, a testament to the effectiveness of the current strategy. The change comes amidst broader efforts by Health and Human Services Secretary Robert F. Kennedy Jr. To re-evaluate childhood vaccination schedules.
The fresh guidance also impacts subsequent doses of the hepatitis B vaccine. The ACIP now recommends testing infants for antibodies between doses, with further vaccinations contingent on the results. This approach, experts note, has not been previously tested and raises questions about potential gaps in protection.
Hepatitis B: A Persistent Threat
Hepatitis B is a highly contagious liver infection transmitted through contact with infected body fluids – blood, semen, and vaginal secretions. While often spread through sexual contact or shared needles, transmission from mother to child during birth remains a significant concern. According to the CDC, pregnant women are routinely tested for hepatitis B, but access to prenatal care isn’t universal, meaning some infections may go undetected. The virus can also survive for up to seven days outside the body, potentially spreading through shared personal items like toothbrushes or razors, or even through accidental contact with blood during activities like sports or play.
The danger of hepatitis B is particularly acute for infants. Babies infected at birth or within their first year of life have a 90% chance of developing a chronic infection, which can lead to serious liver damage, failure, cancer, and even death. For children infected between ages one and five, the risk of chronic infection is around 30%, with one quarter of those developing a chronic infection ultimately dying from the disease.
A History of Success and Concerns About Reversal
The universal hepatitis B vaccination program, initiated in 1991, has been widely lauded as a public health triumph. Data shows an 88.5% decline in reported acute hepatitis B infections since the vaccine’s recommendation in 1982, falling from 9.6 cases per 100,000 population to 1.1 cases per 100,000 population in 2015. The ACIP’s decision to move away from this model has been met with criticism from many in the medical community, who argue that the benefits of universal vaccination far outweigh any perceived risks.
Some ACIP members have advocated for a shared decision-making model, believing it empowers parents with more information. However, critics fear this approach will create confusion and potentially lead to lower vaccination rates, reversing decades of progress. The safety profile of the hepatitis B vaccine is well-established, with over a billion doses administered worldwide since 1982, and common side effects are typically mild, such as headaches, fever, or soreness at the injection site.
What’s Next for Hepatitis B Vaccination?
The implications of this policy change remain to be seen. Public health officials will be closely monitoring vaccination rates and tracking any potential increases in hepatitis B infections among infants and children. The CDC will likely provide further guidance to healthcare providers to facilitate informed discussions with parents about the risks and benefits of hepatitis B vaccination. It is crucial that parents have access to accurate, evidence-based information to make the best decisions for their children’s health.
