why you need the hepatitis a vaccine

The CDC recommends that all children between ages 12 months and 23 months get this vaccine.

The following people are also at risk for the disease and should be vaccinated:

Children and teens through age 18 who live in states or communities that have made this vaccination routine because of a high rate of disease
Men who have sex with men
Anyone who uses illegal drugs

People with chronic (long-term) liver disease
Anyone treated with blood clotting drugs, such as people with hemophilia
People who work with HAV-infected primates or in HAV research laboratories. (HAV is like HIV in animals.)
Travelers to countries where hepatitis A is common. A good source to check is the CDC’s travelers’ health website, which you can search by the country you’re going to.
People adopting or close to a child adopted from a country where hepatitis A is common

You should not get the vaccine if you’re allergic to any ingredients in it or if you had a severe allergic reaction to an earlier dose of it. Tell your doctor or pharmacist about any allergies you have.

If you’re pregnant, let your doctor know. The safety of this vaccine for pregnant women is unknown, although the risk is considered to be very low.
