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

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.
