A Study to Evaluate the Safety of Recombinant Herpes Zoster Vaccine for Healthy Individuals
- Summary
- The purpose of this clinical study is to evaluate the safety and immunogenicity of receiving two doses of recombinant herpes zoster vaccine (CHO cells) (RHZV) in healthy individuals aged 40 years and above. This study will be conducted in 2 substudies: Substudy A (Phase I) and Substudy B (Phase Ⅱ).
