Prevention of Varicella Zoster Virus (VZV)-Reactivation in HIV-positive Individuals Enrolled in a Prospective Immunogenicity and Safety Trial of VZV Vaccine: PROVE-IT-Study
The goal is to demonstrate the immunogenicity and safety of Zostavax® in HIV positive individuals. Study participants are stratified into different patient groups according to their CD4 cell count, viral load and HIV Status.
