Safety and Immunogenicity Study of Live Attenuated Vaccine Against Herpes Zoster in Chinese Adults Aged 50 Years and Older
August 12, 2016 updated by: Beijing Chaoyang District Centre for Disease Control and Prevention
This study evaluates the safety and immunogenicity of live attenuated vaccine in adults aged 50 years and older.
Half of participants will receive high doses of the vaccine,while the other half will receive low doses of the vaccine in phase I clinical trial.
At the phase II clinical trial, participants will be distributed equally to four groups(low、middle, high doses of the vaccine and placebo).
