简要总结
The purpose of this study is to evaluate the immunogenicity and safety of a live attenuated mumps vaccine in healthy infants between 8 - 18 months old with a commercialized live attenuated mumps vaccine as the control vaccine.
详细描述
This study is a randomized, blind, single-center, controlled phase III clinical trial. The purpose of this study is to evaluate the immunogenicity and safety of a live attenuated mumps vaccine manufactured by Sinovac (Dalian) Vaccine Technology Co., Ltd. The control vaccine is a commercialized live attenuated mumps vaccine manufactured by Zhejiang VACN bio-pharmaceutical Co. Ltd. All participants are healthy infants between 8 - 18 months old, and will be randomly assigned into experimental group or control group in the ratio 1:1.

结局指标
主要结局
The seroconversion rates (SCRs) of susceptible subjects in each group
时间窗: 28 days
Subjects whose pre-immune HI antibody level \< 1:2 are considered susceptible; among these subjects, those with post-immune HI antibody level ≥ 1:2 are considered seroconverted.
次要结局
- The overall SCRs of each group(28 days)
- The incidences of adverse events (AEs) of each group(28 days)
- The incidences of serious adverse events (SAEs) of each group(28 days)
- The post-immune geometric mean titers (GMTs) of susceptible subjects in each group(28 days)
- The overall post-immune GMTs of each group(28 days)
