Clinical Trial Summary

This study is a randomized and controlled Phase IV clinical trial.The purpose of this study is to evaluate the immunogenicity and safety of combined immunization with live attenuated varicella vaccine and inactivated hepatitis A vaccine in children aged 12-15 months.

Description:

This study is a randomized and controlled phase IV clinical trial in children aged 1 year old (12-15 months).The purpose of this study is to evaluate the immunogenicity and safety of live attenuated varicella vaccine co-administration with inactivated hepatitis A vaccine .The live attenuated varicella vaccine was manufactured by Sinovac (Dalian) Vaccine Technology Co., Ltd,the inactivated hepatitis A vaccine was manufactured by Sinovac Biotech Co., Ltd.A total of 450 subjects aged 1 year old (12-15 months) were be enrolled.Subjects were be randomly divided into 2 groups in a ratio of 1:1.Subjects in the combined immunization group received one dose of live attenuated varicella vaccine and the first dose inactivated hepatitis A vaccine on day 0 and the second dose of inactivated hepatitis A vaccine on day 180.Subjects in the Non-combined immunization group received one dose of live attenuated varicella vaccine on day 0,the first dose of inactivated hepatitis A vaccine on day 42 and the second dose of inactivated hepatitis A vaccine on day 222.
