    Hepatitis A Vaccine for Adults

    The hepatitis A vaccine can prevent hepatitis A, which can be a serious (although rarely fatal) liver disease that may require hospitalization. The hepatitis A virus, present in the stool of infected people, spreads through:

    • Are a man who has sex with men

    There are also combination vaccines for adults that protect against both hepatitis A and hepatitis B. However, these have a different dosing schedule. Ask your doctor for details. You might prefer this option if, for example, you are traveling to countries with high rates of both diseases.
