Outcome Measures

Primary Outcome Measures :
  1. Percentage of Subjects With an Immune Response Against Diphtheria, Tetanus and Pertussis, When Tdap is Concomitantly Administered With MenACWY-CRM Compared to Tdap Given Concomitantly With Saline Placebo [ Time Frame: 1 month after vaccination (Day 29) ]

    To demonstrate that the immunogenicity of one injection of Tdap vaccine, concomitantly administered with MenACWY-CRM vaccine, is not inferior to that of one injection of Tdap vaccine, concomitantly administered with saline placebo, in terms of

    1. the percentage of subjects with antibody levels against diphtheria toxin ≥ 1.0 IU/mL and against tetanus toxin ≥ 1.0 IU/mL and
    2. the percentage of subjects with at least 4 fold increase in antibody levels against pertussis toxin (PT), filamentous hemagglutinin (FHA) and pertactin (PRN) at 1 month after immunization, as measured by enzyme linked immunosorbent assay (ELISA).


Secondary Outcome Measures :
  1. Percentage of Subjects With Anti-diphtheria and Anti-tetanus Concentrations ≥ 0.1 IU/mL When Tdap is Administered Concomitantly With MenACWY-CRM Vaccine Compared to Tdap Given Concomitantly With Saline Placebo [ Time Frame: 1 month after vaccination (Day 29) ]
    The percentage of subjects with anti-diphtheria and anti-tetanus concentrations ≥ 0.1 IU/mL (as measured by ELISA) following concomitant administration of Tdap vaccine with MenACWY-CRM vaccine as compared to when Tdap was given concomitantly with saline placebo.

  2. Geometric Mean Concentrations (GMCs) of Antibodies Against Diphtheria,Tetanus and Pertussis Antigens After Concomitant Administration of Tdap With MenACWY-CRM Compared to Tdap Given Concomitantly With Saline Placebo [ Time Frame: 1 month after vaccination (Day 29) ]
    The geometric mean concentrations of antibodies ≥ 0.1 IU/mL against diphtheria, tetanus and pertussis (PT, FHA and PRN) antigens in subjects, as measured by ELISA, following concomitant administration of Tdap with MenACWY-CRM as compared to when Tdap given concomitantly with saline placebo.

  3. Geometric Mean Ratios of Antibody Concentrations Against Diphtheria,Tetanus and Pertussis Antigens When Tdap is Administered Concomitantly With MenACWY-CRM Vaccine Compared to Tdap Given Concomitantly With Saline Placebo [ Time Frame: 1 month after vaccination (Day 29) ]
    The geometric mean ratios (GMRs- day 29/day 1) of post-vaccination versus pre- vaccination antibody concentrations against diptheria, tetanus and pertussis (PT, FHA and PRN) antigens following concomitant administration of Tdap vaccine with MenACWY-CRM vaccine as compared to when Tdap was given concomitantly with saline placebo.

  4. Percentage of Subjects With Serum Bactericidal Antibody Titers ≥1:4 and ≥1:8, When MenACWY-CRM is Concomitantly Administered With Tdap Vaccine Compared to MenACWY-CRM Given Concomitantly With Saline Placebo [ Time Frame: 1 month after vaccination (Day 29) ]

    The percentage of subjects with serum bactericidal antibody titers(hSBA) ≥ 1:4 and ≥ 1:8 against Neisseria meningitidis serogroups A,C,W and Y,following concomitant administration of MenACWY-CRM vaccine with Tdap vaccine as compared to when MenACWY-CRM was given concomitantly with saline placebo.

    The serum bactericidal antibodies directed against N.meningitidis serogroup A, C, W and Y, are measured by human complement Serum Bactericidal Assay (hSBA).


  5. The hSBA Geometric Mean Titers Against N.Meningitidis Serogroups A,C,W and Y, When MenACWY-CRM is Concomitantly Administered With Tdap Vaccine Compared to MenACWY-CRM Given Concomitantly With Saline Placebo [ Time Frame: 1 month after vaccination (Day 29) ]

  6. Geometric Mean Ratios of hSBA Titers Against N.Meningitidis Serogroups A,C,W and Y, When MenACWY-CRM is Concomitantly Administered With Tdap Compared to MenACWY-CRM Given Concomitantly With Saline Placebo [ Time Frame: 1 month after vaccination (Day 29) ]

    Seroresponse to MenACWY-CRM is defined as a pre-vaccination hSBA titer < 1:4 to a post-vaccination hSBA titer of ≥ 1:8 or a pre-vaccination hSBA titer ≥ 1:4 to a post-vaccination titer of at least four times the baseline hSBA titer.


  8. Number of Subjects With Solicited Local and Systemic Adverse Events When Tdap is Concomitantly Administered With MenACWY-CRM Compared to When MenACWY-CRM is Concomitantly Administered With Saline Placebo [ Time Frame: Day 1-7 after any vaccination ]
    The number of subjects reporting solicited local and systemic reactions following concomitant administration of MenACWY-CRM vaccine and Tdap vaccine as compared to when MenACWY-CRM vaccine was concomitantly administered with saline placebo.

    The number of subjects reporting any unsolicited adverse events (AEs) when Tdap is concomitantly administered with MenACWY-CRM as compared to when MenACWY-CRM vaccine or Tdap vaccine was concomitantly administered with saline placebo.
