Hepatitis is a serious disease caused by a virus. Hepatitis causes inflammation of the liver, vomiting, and jaundice (yellowing of the skin or eyes). Hepatitis can lead to liver cancer, cirrhosis, or death.

Hepatitis B is a disease of the liver that is spread through blood or bodily fluids, sexual contact or sharing IV drug needles with an infected person, or during childbirth when the mother is infected.

The hepatitis B adult vaccine is used to help prevent this disease in adults.

This vaccine works by exposing you to a small amount of the virus, which causes the body to develop immunity to the disease. This vaccine will not treat an active infection that has already developed in the body.

Vaccination with hepatitis B adult vaccine is recommended for all adults who are at risk of getting hepatitis B. Risk factors include: having more than one sex partner; being a homosexual male; having sexual contact with infected people; having chronic liver disease; having diabetes and being under age 60; having HIV or AIDS; using intravenous (IV) drugs; being on dialysis or receiving blood transfusions; working in an institution for developmentally disabled patients; working in healthcare or public safety and being exposed to human blood; being in the military or traveling to high-risk areas; and living with a person who has hepatitis B.

Like any vaccine, the hepatitis B vaccine may not provide protection from disease in every person.
