What is hepatitis A vaccine? What are the uses for hepatitis A vaccine?
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.
The hepatitis A vaccine is used for the prevention of disease caused by hepatitis A virus in persons 12 months of age and older. The primary dose should be given at least 2 weeks prior to expected exposure to HAV.
Hepatitis A vaccine was approved in 2005.

- Children should be vaccinated at 12 through 23 months of age.
- Alternatively, anyone over the age of 12 months who wishes to be protected from the hepatitis A virus can be vaccinated at any time.
- Travelers are advised to get vaccinated at least 2 weeks before travelling.
Which drugs or supplements interact with hepatitis A vaccine?

Examples include fingolimod (Gilenya), belimumab (Benlysta), anakinra (Kineret), adalimumab (Humira), infliximab (Remicade), antineoplastic agents (anti-cancer medications), and other drugs that suppress the immune system.
