Biological: Concomitant administration of EV71vaccine with EPI vaccines
Biological: Single injection of EPI vaccine
Biological: EV71 Vaccine only
Registration Number
NCT04111432
Lead Sponsor
Sinovac Biotech Co., Ltd
Brief Summary

The purpose of this study is to evaluate the safety and immunogenicity of concomitant administration of EV71 vaccine with measles mumps, and rubella combined live attenuated vaccine/ encephalitis live attenuated vaccine.

Detailed Description

This study is an open-label, single-center, randomized, comparative phase IV clinical trial. The purpose of this study is to evaluate the safety andimmunogenicity of concomitant administration of EV71 vaccine manufactured by Sinovac (Beijing) Vaccine Technology Co., Ltd. with measles mumps, and rubella combined live attenuated vaccine/ encephalitis live attenuated vaccine. 360 healthy infants of 8 months old as participants are randomly assigned into three experimental groups in the ratio 1:1:1. The group I receive EV71 Vaccine (first dose)\&measles mumps, and rubella combined live attenuated vaccine on day 0 and EV71 vaccine (second dose)\&encephalitis live attenuated vaccine on day 30. The group II receive measles mumps, and rubella combined live attenuated vaccine on day 0 and encephalitis live attenuated vaccine on day 30. The group III receive the first and second dose of EV71 Vaccine on day 0 and day 30 respectively.
