Efficiency of the Hepatitis B Sci-B-Vac Vaccine in HIV Positive Patients

October 5, 2011 updated by: Tel-Aviv Sourasky Medical Center

Efficiency of the Novel Hepatitis B Vaccine Sci-B-Vac in HIV Positive Patients, a Prospective Cohort Study

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.

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.

  • Allocation: N/A
  • Interventional Model: Single Group Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / 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
