Summary

This study will evaluate the safety and immunogenicity of a heat-treated VZV vaccine in autologous or allogeneic hematopoietic cell transplant (HCT) recipients, human immunodeficiency virus (HIV)-infected participants with a baseline cluster of differentiation 4 (CD4) cell count ≤200 cells/mm\^3, participants with solid tumor malignancy (STM; breast, colorectal, lung, or ovarian malignancies) receiving chemotherapy, and participants with hematologic malignancy (HM; leukemia or leukemia-like disease, lymphoma or lymphoma-like disease, or multiple myeloma). The primary hypothesis is that the heat-treated VZV vaccine will elicit significant VZV-specific immune responses measured by either glycoprotein-based enzyme-linked immunosorbent assay (gpELISA) or VZV gamma interferon enzyme-linked immunospot (IFN-ELISPOT) at 28 days post dose vaccination 4 in, HIV-infected participants, participants with STM, and participants with HM. The primary immunogenicity objective and endpoints were considered by the protocol as exploratory for the autologous and allogeneic HCT groups.
