Hepatitis A is a liver disease.
Hepatitis (HEP-ah-TY-tis) makes your liver swell and stops it from working right.
You need a healthy liver. The liver does many things to keep you alive. The liver fights infections and stops bleeding. It removes drugs and other poisons from your blood. The liver also stores energy for when you need it.
Hepatitis A is caused by a virus.
A virus is a germ that causes sickness. (For example, the flu is caused by a virus.) People can pass viruses to each other. The virus that causes hepatitis A is called the hepatitis A virus.

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 turn 2 years old. Children aged 2 to 18 will need three shots. The shots are spread out over a year. Adults get two or three shots over 6 to 12 months.
You need all of the shots to be protected. If you miss a shot, call your doctor or clinic right away to set up a new appointment.
