An Introduction to the Hepatitis A Vaccine
A vaccine is a drug that you take when you are healthy that keeps you from getting sick. Vaccines teach your body to attack certain viruses, like the hepatitis A virus.
The hepatitis A vaccine is given through a shot. Children can get the vaccine after they are 1 year old. It is recommended that children receive the vaccine between 12 and 23 months of age. The second shot should follow 6 to 12 months later. Adults get two shots over a period of 6 to 12 months.
