From blog.AIDS.gov:

People living with HIV who are also living with viral hepatitis are at increased risk for serious, life threatening complications.  As a result, all persons living with HIV should be tested for Hepatitis B and Hepatitis C by their doctors. Co-infection with hepatitis may also complicate the management of HIV infection.

In order to prevent co-infection with Hepatitis B, the Advisory Committee on Immunization Practices recommends universal Hepatitis B vaccination of susceptible patients with HIV/AIDS.  Hepatitis A and Hepatitis B vaccines are also recommended for all men who have sex with men, users of illicit drugs, and others at increased risk of infection. There is no vaccine for Hepatitis C.
