Outcome Measures

Primary Outcomes (1)

  • Safety index-incidence of adverse reactions

    Incidence of adverse reactions 0 to 30 days after each dose of experimental vaccine

    Day 0-30 after each dose of experimental vaccine

Secondary Outcomes (9)

  • Safety index-incidence of adverse reactions

    Day 0-7 after each dose of experimental vaccine

  • Safety index-incidence of abnormal indicators

    Day 3 after vaccination after each dose of experimental vaccine

  • Safety index-Incidence of serious adverse events during the safety observation period

    1 month after vaccination ,6 months after primary immunization or 1 month after booster immunization

  • Immunogenicity index-Geometric mean concentrations (GMC) and GMI of specific IgG for each serotype

    Day 30 after vaccination

  • Immunogenicity index-Geometric mean titers (GMT) and GMI of serotype specific opsonophagocytic antibody OPA for each serotype

    Day 30 after vaccination

  • +4 more secondary outcomes
