100HBV vaccination is of paramount importance among HIV positive persons due to an increased risk of infection and disease progression. The most widely used ENGERIX B vaccine reaches a lower rate of vaccination (20-70%) among HIV positive vaccinees (compared to over 90% in the normal population). Sci-B-Vac is novel vaccine containing 3 antigens and is therefore more immunogenic (as opposed to one in ENGERIX B). Its use has been associated with higher and more rapid vaccination rates. Therefore, it has a theoretical advantage in HIV positive individuals.
A cohort of 100 HIV positive, HBV negative individuals who have not been vaccinated against HBV before will be prospectively given 3 doses of Sci-B-Vac at 0, 1 and 6 months. HBV antibodies will be checked one month after every dose given.
10 microgram/ml hepatitis B surface antigen, 1 ml given intramuscularly
The study involves only one, open label arm. Rate of immunization will be compared to results obtained using the ENGERIX B vaccine among HIV positive persons in formerly published, historical cohorts.
Inclusion Criteria: HBV negative HIV positive individuals Above the age of 18 Treated at the TASMC Aids clinic, who have signed and informed consent and have never been vaccinated against HBV before Exclusion Criteria: Pregnant women HBV positivity Previous HBV vaccination
