The vaccine is an injection that helps protect you 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. You 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. A baby can be infected at birth if his or her mother has hepatitis B.
