MedicalResearch.com: What is the background for this study? What are the main findings?

Dr. Launay: In patients with HIV infection, responses to standard HBV vaccination regimens remain suboptimal compared with responses in HIV seonegative individuals. We previously reported that alternative regimens (a 4 injection IMdouble dose regimen and a 4 injection intradermal low dose regimen) improve antibody response compared with the standard HBV vaccination regimen (ANRS HB03 VIHVAC-B study). Further precision on the duration of response achieved with alternative HBV vaccination regimes was needed.

We report in this paper the results from the follow-up of the study.

The results of this study show that the 4 dose IM regimen induces higher seroconversion rate but also higher long term seroprotection in HIV infected patients

MedicalResearch.com: What should clinicians and patients take away from your report?

Dr. Launay: The 4-dose intramuscular regimen is well tolerated and induces higher and more prolongated seroprotection that the standard regimen. It should become the standard for HBV vaccination in HIV infected patients. 

MedicalResearch.com: What recommendations do you have for future research as a result of this study?

Dr. Launay: Further studies are needed to evaluate the clinical protection conferred by higher immune response to HBV vaccination
