In a pregnant patient with hepatitis B virus infection, what is the recommended management for the newborn at birth?

Neonatal prophylaxis for a baby born to an hepatitis B–infected mother relies on both immediate protection and long-term immunity. Administering the hepatitis B immune globulin (HBIG) and the hepatitis B vaccine to the newborn within the first hours of life provides this dual effect: HBIG gives rapid, passive antibodies to neutralize any virus present at birth, while the vaccine stimulates the infant’s own immune system to develop lasting protection. Relying on the vaccine alone leaves a window where infection could occur, and giving HBIG to the mother during pregnancy isn’t the standard way to prevent neonatal infection. Completing the vaccine series later ensures durable immunity.
