Hepatitis A is a contagious liver disease caused by the hepatitis A virus (HAV). The infection is spread by eating contaminated food or drinking contaminated water. It can also be spread through close person-to-person contact such as household contact with an infected person. There is no specific treatment for hepatitis A infection, but hepatitis A vaccine can prevent HAV infection.
Hepatitis A vaccine is very safe and effective. You cannot get hepatitis A from the vaccine. Side effects, when they occur, are minimal and may include soreness at the injection site or a headache. As with any medicine, there are very small risks that serious problems could occur after getting the vaccine. However, the potential risks associated with hepatitis A disease are much greater than the potential risks associated with the hepatitis A vaccine. People who have had a severe allergic reaction to hepatitis A vaccine or to any of its components should not receive hepatitis A vaccine.
