Hepatitis B

Your newborn should get this shot even before leaving the hospital, and receive another dose at 1 to 2 months and a third at 6 to 18 months. The vaccine protects against an incurable, liver-infecting virus, hepatitis B, which can be passed to a baby during childbirth if the mother is infected.

This virus spreads through contact with blood or other body fluids (sharing toothbrushes and utensils can put you at risk).

Soreness at the site of the shot, or a slight fever, is the most common side effect, according to Gabrielle Gold-von Simson, MD, assistant professor of pediatrics at NYU Langone Medical Center in New York.
