New Science, New Guidance: Rethinking Hepatitis B Vaccination at Birth

In this episode of Decoding Health, we examine a recent shift in CDC guidance regarding hepatitis B vaccination recommendations for newborns. Long criticized for lagging behind evolving science, the CDC has now revised its position after reviewing updated risk-benefit data presented during a publicly broadcast panel discussion.

Sparked by the birth of the host’s second grandchild, the conversation breaks down how hepatitis B is transmitted, why infection risk for infants born to hepatitis-negative mothers is extremely low, and what new evidence prompted the CDC to remove its universal newborn recommendation in these cases. We explore the concept of biological immune burden, emerging discussions around neurodevelopmental risk, and why updated guidance may take time to reach hospitals and pediatric practices.

This episode equips parents and healthcare consumers with the knowledge needed to advocate for informed decision-making during postpartum care, using primary-source evidence directly from CDC proceedings.
