结局指标
主要结局
Percentages of Subjects With a Seroresponse to Measles, Mumps, Rubella and Varicella Following Concomitant Administration of MMRV Vaccine With MenACWY-CRM Vaccine
时间窗: 6 weeks post vaccination
Percentages of subjects with seroresponses to measles, mumps, rubella and varicella after one dose of MMRV vaccine (at 12 months) when given concomitantly with MenACWY-CRM vaccine compared to when MMRV vaccine was given alone, are reported. Seroresponse was defined as the percentage of initially seronegative subjects who show seroconversion to measles (≥255 mIU/mL), mumps (≥10 ELISA Ab units), rubella (≥10 IU/mL) and the percentage of initially seronegative subjects who show seroprotection (≥5 gp ELISA units/mL) for varicella. Immunogenicity to measles, mumps, rubella and varicella at 6 weeks after vaccination with one dose of MMRV given concomitantly with MenACWY-CRM was considered non-inferior to immunogenicity of MMRV administered alone if the lower limit of two-sided 95% CI of the difference in the percentage of subjects with seroconversion for measles, mumps, and rubella, and seroprotection for varicella was greater than -5% (measles, mumps and rubella) and -10% (varicella).
Percentages of Subjects With Serum Bactericidal Titers ≥1:8 Following Concomitant Administration of MenACWY-CRM Vaccine With MMRV Vaccine.
时间窗: 6 weeks post second dose
Percentages of subjects with hSBA ≥1:8, against N.meningitidis serogroups A, C, W-135, and Y following two doses of MenACWY-CRM vaccine (at 7-9 months and 12 months) when concomitantly administered with MMRV vaccine (12 months) compared to when MenACWY-CRM vaccine was given alone, are reported. The serum bactericidal antibodies directed against N.meningitidis serogroups A, C, W-135, and Y, were measured by human complement Serum Bactericidal Assay (hSBA). The immune response of MenACWY-CRM given concomitantly with MMRV was considered non-inferior to the immunogenicity of MenACWY-CRM administered alone if the lower limit of the two-sided 95% CI around the difference of the percentage of subjects with hSBA ≥1:8 at 6 weeks after the second dose of MenACWY-CRM given to 12-month old toddlers {P MMRV+MenACWY minus P MenACWY} was greater than -10% for each serogroup.
Percentages of Subjects With hSBA ≥1:8 Following Two Doses of MenACWY-CRM Vaccine
时间窗: 6 weeks post vaccine dose 2
The antibody response following two doses of MenACWY-CRM vaccine (at 7-9 months and 12 months) was considered adequate if the lower limit of the two-sided 95% CI for the percentage of subjects with hSBA ≥1:8, at 6 weeks following the second dose of MenACWY-CRM, was greater than 85% for serogroups C, W-135, or Y and greater than 65% for serogroup A.

- Geometric Mean Titers Against Measles, Mumps, Rubella and Varicella Following One Dose of MMRV Vaccine.(6 weeks post vaccination)
- Percentages of Subjects Showing Seroconversion Response to Varicella Following Concomitant Administration of MMRV With MenACWY-CRM Vaccine.(6 weeks post vaccination)
- Percentages of Subjects With hSBA ≥1:4 and hSBA ≥1:8 Following One Dose of MenACWY-CRM Vaccine(1 month post vaccine dose 1)
- Geometric Mean Titers After One Dose of MenACWY-CRM Vaccine(1 month post vaccine dose 1)
