Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Varicella-zoster virus (VZV) is a herpesvirus that causes two distinct clinical syndromes.Primary infection is manifested as varicella (chickenpox), whereas reactivation of latent VZV results in a localized eruption known as herpes zoster. Most people 40 years of age or older had evidence of previous VZV infection. This study plans to have 522 adults above 40 years old involoved in a randomized, double-blind, placebo-controlled trial of an investigational live attenuated zoster vaccine. The investigational vaccine is produced by Shanghai Institute of Biological Products Co., Ltd. The safety and immunogenicity of the zoster vaccine is evaluated.
