Hepatitis B Vaccine For Children


The hepatitis B 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 at birth if his or her mother has hepatitis B.
