Primary Outcome Measures:
  • To evaluate overall safety of EV71 vaccine in children, throughout the study period [ Time Frame: 2 years after study initiation ]
    Occurrence of overall adverse events and serious adverse events during the entire period of study.

Secondary Outcome Measures:
  • To evaluate immunogenicity, serum neutralizing antibody titers humoral immune response, induced by candidate vaccine [ Time Frame: 2 years from study initiation ]

    To evaluate the immunogencity in terms of

    • Geometric mean titer (GMT) of EV71 neutralizing antibody titers
    • Post-vaccination-to-pre-vaccination GMT ratio of EV 71 neutralizing antibody titers
    • Seropositivity rate
