Brief Summary

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

This a randomized, blind, controlled clinical trial of live attenuated varicella vaccines manufactured by Sinovac (Dalian) Vaccine Technology Co., Ltd .The purpose of this study is to evaluate the immunogenicity of a two doses vaccination of investigational vaccine with 0,28 day, 0,42 day and 0,56 day immunization schedule in population aged ≥13 years old.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study is a randomized, blind, controlled phase # clinical trial in population aged ≥13 years old. The experimental vaccine will be manufactured by Sinovac (Dalian) Vaccine Technology Co., Ltd.A total of 2400 subjects aged 13 years and older will be enrolled with1200 subjects in 13 \~ 17 years old group and1200 subjects in 18 years and older group.960 subjects in each age group will be randomly divided into experimental group and control group according to 1:1 ratio,and subjects will receive two doses of vaccine with the immunization course of 0,28 days, 0,42 days or 0,56 days. An additional 240 subjects in each age group will be randomly divided into experimental group and control group according to 2:1 ratio to receive two doses of the experimental vaccine or placebo with the immunization course of 0, 70 days.In addition,400 subjects including 320 people of experimental group in different immunization course according to the difference of age and 80 people of placebo group according to the difference of age will be selected to collect blood about 3ml each time to evaluate immunity persistence of live attenuated varicella vaccines at 3 and 5 years after the whole immunization.
