Giving the hepatitis B Vaccine at birth is a routine part of newborn care in the United States. A Big news story recently is that federal guidance has shifted, moving from a universal recommendation to a shared decision-making approach for some infants.

In this episode, I take a neutral, evidence-based look at:

• What exactly changed in the Hep B birth dose guidance

• What hepatitis B is and why age at infection matters

• Why infants and adults respond so differently to the virus

• How universal newborn vaccination reduced infections by 99.9%

• Where theory and real-world healthcare systems diverge

This discussion avoids politics and focuses on the medicine, the data, and how policy decisions play out in everyday clinical practice.
