What is hepatitis a vaccine-injection, and how does it work (mechanism of action)?

Hepatitis A vaccine (Havrix, Vaqta) is used to prevent hepatitis A, a type of liver disease that is caused by the hepatitis A virus (HAV). Hepatitis A is usually spread when a person ingests fecal matter from contact with food, drinks, or objects which have been contaminated by feces or stool of an HAV-infected person. Hepatitis A infection can be mild with no symptoms or a serious illness that can rarely cause liver failure and death. Getting vaccinated against the hepatitis A virus is the best way to prevent these problems.

The hepatitis A vaccine does not cause hepatitis because it does not contain the live virus. It contains inactivated hepatitis A virus. The vaccine works by stimulating the body to produce antibodies, which are proteins that will fight and kill the virus and prevent hepatitis A infection.

Hepatitis A vaccine was approved in 2005.
