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.

Condition or disease Intervention/treatment Phase
Hand, Foot and Mouth Disease Biological: Concomitant administration of EV71vaccine with EPI vaccines Biological: Single injection of EPI vaccine Biological: EV71 Vaccine only Phase 4

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.

Primary Outcome Measures :
  1. The seroconversion rates（SCR） of the EV71 neutralizing antibody 30 days after two dose of EV71 vaccines [ Time Frame: 30 days after two dose of EV71 vaccines ]
    Immunogenicity indicator


Secondary Outcome Measures :
  1. The seroconversion rates（SCR） of the Measles IgG antibody，Rubella 30 IgG antibody and Mumps IgG antibody 60 days after one dose of MMR vaccine [ Time Frame: 60 days after one dose of MMR vaccine ]

    Immunogenicity indicator

  3. EV71 neutralizing antibody positive rate 30 days of two dose of EV71 vaccines [ Time Frame: 30 days after two dose of EV71 vaccines ]
    Immunogenicity indicator

  4. The Geometric mean titer (GMT) of the EV71 neutralizing antibody 30 days of two dose of EV71 vaccines [ Time Frame: 30 days after two dose of EV71 vaccines ]
    Immunogenicity indicator

  5. Measles IgG antibody，Rubella 30 IgG antibody and Mumps IgG antibody positive rate 60 days after one dose of MMR vaccine [ Time Frame: 60 days after one dose of MMR vaccine ]
