Brief Summary

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. The investigational vaccine of this study is produced by Changchun BCHT biotechnology Co. It's a live attenuated herpes zoster vaccine based on the production process of live attenuated chickenpox vaccine.This study plans to have 25000 adults aged 40 years or older and involves in a randomized, double-blind, placebo-controlled trial . The primary outcome is to evaluate the efficacy of the vaccine against herpes zoster 30 days after vaccination and the safety of the vaccine.
