Brief Summary:
HBV 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.

Condition or disease Intervention/treatment Phase
HIV Biological: Sci-B-Vac Not Applicable

Detailed Description:
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.

Arm Intervention/treatment
Experimental: Sci-B-Vac
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.
Biological: Sci-B-Vac
10 microgram/ml hepatitis B surface antigen, 1 ml given intramuscularly

Primary Outcome Measures :
  1. HBV immunization rate after 1, 2 and 3rd dose of Sci-B-Vac [ Time Frame: 12 months ]
    HBV Surface antibodies will be obtained one month after each Sci-B-Vac dose for each vaccinee. Rate and rapidity of immunization will be measured.
