Primary outcomePrimary: Part 1: Geometric Mean Fold Rise of the Varicella-Zoster Virus (VZV)-Specific Immune Responses Measured by Glycoprotein Enzyme-Linked Immunosorbent Assay in Gamma-Irradiated VZV Vaccine A Recipients — 2.18 Ratio — p=<0.0001
Summary
The purpose of this study was to assess the safety and tolerability of gamma-irradiated varicella-zoster virus (VZV) vaccine A (Part 1) and gamma-irradiated VZV vaccine B and C (Part 2) and to determine if they were immunogenic when administered to healthy individuals, as measured by VZV-specific antibody responses by glycoprotein enzyme-linked immunosorbent assay (gpELISA). The primary hypothesis was that gamma-irradiated VZV vaccine A (Part 1) and gamma-irradiated VZV vaccine B and C (Part 2) would elicit an acceptable VZV-specific immune response. The secondary hypothesis for Part 1 of the study was that heat-treated VZV vaccine would elicit an acceptable VZV-specific immune response.
