Hepatitis B Vaccine for Children

Medically reviewed by Last updated on Oct 31, 2022.

What is the hepatitis B vaccine?

The vaccine is an injection that helps protect your child from the virus that causes hepatitis B. Hepatitis B is a serious liver infection. The virus is usually spread through contact with the blood or body fluids of an infected person. Your child can also get it by touching an object that has the virus on it. The virus can live on an object for up to 7 days. Your baby can be infected during birth if his or her mother has hepatitis B. This increases his or her risk for developing chronic hepatitis B.

When should my child get the hepatitis B vaccine?

The hepatitis B vaccine is usually given in 3 doses:

  • Babies are routinely given a dose of the hepatitis B vaccine within 24 hours of birth. If your baby's mother has hepatitis B, your baby should get the vaccine within 12 hours of birth.
  • A second dose is given at 1 to 2 months.
  • A third dose is given at 6 to 18 months.
