The Centers for Disease Control and Prevention's vaccine advisory panel has changed its long-standing recommendation regarding the hepatitis B vaccine for newborns. On Friday, the Advisory Committee on Immunization Practices (ACIP) voted 8-3 to recommend that infants born to mothers who test negative for hepatitis B should not necessarily receive the vaccine within 24 hours of birth. Instead, the panel now suggests that parents consult with healthcare providers about the timing of the first dose, which can be delayed until at least 2 months of age.

This decision marks a significant shift from the CDC's previous guidance, which has been in place for over 30 years. The vote followed a two-day meeting filled with heated discussions and confusion over the voting process. Some panel members expressed concerns about the implications of delaying the vaccine, particularly given the risks associated with hepatitis B, which can lead to chronic infection, liver disease, and even death.

Dr. Joseph Hibbeln, an ACIP member, emphasized the need for credible data in decision-making. "We have to make decisions with the data that we have, and we must use only the credible data to make the decisions, and not speculations and not hypotheses," he stated. Many medical experts, including representatives from the American Academy of Pediatrics, opposed the change, arguing it could leave newborns vulnerable to infection.

The panel's new recommendation does not alter the existing guidance for infants born to mothers who test positive for hepatitis B or whose infection status is unknown. Hepatitis B can be transmitted during childbirth, making timely vaccination critical for these infants.

The decision has raised concerns among public health experts. Chari Cohen, president of the Hepatitis B Foundation, noted that the new guidelines could create confusion for healthcare providers and parents. "The more confusing we make these recommendations, the harder this is going to be for clinicians to implement," Cohen said.

The ACIP's vote comes amid a backdrop of skepticism regarding vaccines, particularly following the appointment of new panel members by Health and Human Services Secretary Robert F. Kennedy Jr. Many states have begun to disregard the panel's guidance, opting instead to follow recommendations from professional medical societies.

FDA Commissioner Marty Makary commented on the situation, stating that there is no scientific evidence supporting the need for a universal birth dose of the hepatitis B vaccine. He suggested that parents should have the option to delay vaccination until their child is older. However, this perspective is not universally accepted among medical professionals, who argue that delaying the vaccine could lead to increased infections, especially since not all pregnant women are tested for hepatitis B.

The CDC has previously reported that the universal birth dose of the hepatitis B vaccine has significantly reduced infection rates among children since its recommendation in 1991. A CDC analysis estimated that the vaccine has prevented over 6 million infections and nearly 1 million hospitalizations among children born from 1994 to 2023.

The panel's new recommendation awaits approval from the CDC director, which could impact insurance coverage and state vaccination policies. The hepatitis B vaccine is typically administered as part of a three-dose series, with the first dose ideally given shortly after birth. Public health experts warn that any changes to this schedule could have serious implications for child health and safety.
