Clinical Trial Summary

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).

Type	Measure	Description	Time frame	Safety issue
Primary	Evaluate the Rate of Adverse reactions of live attenuated Herpes zoster Vaccine in Chinese Adults.	Adverse reactions associated with vaccine will be observed in Chinese Adults ( 50 years and older) after vaccination. Solicited local adverse events include Pain, Redness, Swelling, Induration, Rash, Pruritus at injection site. solicited general adverse events include Fever, Nausea, Vomiting, Diarrhea, Decreased appetite, Be agitated (irritability, abnormal crying), fatigue, allergy	42 days	Yes
Secondary	Evaluate the seroconversion rate of anti-herpes zoster virus antibodies in serum of adults after vaccination.	The seroconversion rate of anti-herpes zoster virus antibodies will be evaluated in serum of adults within the first 42 days after vaccination.	6 months	No
