11. Hepatitis A Vaccination - Adults at Increased Risk of Infection

There are other groups that have been recommended for vaccination; and in hepatitis A, most of the disease does not occur in these groups, but they play an important role in transmission communities. This includes people who travel to countries who have high rates of the disease, as well as men who have sex with men, injection and non-injection drug users, persons who receive clotting factor concentrates, and persons with chronic liver disease. Unfortunately, we have not done very well in these populations.
