- Percentages of Subjects With hSBA Seroresponse, in Healthy Children 2 to 5 Years of Age [ Time Frame: 1 month postvaccination ]
The immunogenicity of a single dose of MenACWY-CRM is compared with the immunogenicity of a single dose of the licensed ACWY polysaccharide vaccine, in terms of the percentages of subjects with seroresponse directed against N. meningitidis serogroups A, C, W-135, and Y.
Seroresponse: For a subject with hSBA <1:4 at baseline, seroresponse is defined as a postvaccination hSBA ≥ 1:8; for a subject with hSBA ≥ 1:4 at baseline, seroresponse is defined as a postvaccination hSBA titer of at least 4 times the baseline.
- Percentages of Subjects With hSBA Seroresponse, in Healthy Children 6 to 10 Years of Age. [ Time Frame: 1 month postvaccination ]
The immunogenicity of a single dose of MenACWY-CRM is compared with the immunogenicity of a single dose of the licensed ACWY polysaccharide vaccine, in terms of the percenatages of subjects with seroresponse directed against N. meningitidis serogroups A, C, W-135, and Y.
Seroresponse: For a subject with hSBA <1:4 at baseline, seroresponse is defined as a postvaccination hSBA ≥ 1:8; for a subject with hSBA ≥ 1:4 at baseline, seroresponse is defined as a postvaccination hSBA titer of at least 4 times the baseline.

Seroresponse: For a subject with hSBA <1:4 at baseline, seroresponse is defined as a postvaccination hSBA ≥ 1:8; for a subject with hSBA ≥ 1:4 at baseline, seroresponse is defined as a postvaccination hSBA titer of at least 4 times the baseline.
- Geometric Mean Titers (hSBA), in Healthy Children 2 to 10 Years of Age. [ Time Frame: 1 month postvaccination ]The immunogenicity of a single dose of MenACWY-CRM is compared with the immunogenicity of a single dose of the licensed ACWY polysaccharide vaccine, in terms of the number of subjects with hSBA (human Serum Bactericidal Activity) Geometric Mean Titers (GMTs) response against N. meningitidis serogroups A, C, W-135, and Y.
- Percentages of Subjects With hSBA ≥ 1:8, in Healthy Children 2 to 5 and 6 to 10 Years of Age. [ Time Frame: 1 month postvaccination ]The immunogenicity of a single dose of MenACWY-CRM is compared with the immunogenicity of a single dose of the licensed ACWY polysaccharide vaccine, in terms of the percenategs of subjects with seroresponse directed against N. meningitidis serogroups A, C, W-135, and Y.
- Geometric Mean Titers (hSBA), in Healthy Children 2 to 5 and 6 to 10 Years of Age. [ Time Frame: 1 month postvaccination ]The immunogenicity of a single dose of the Novartis MenACWY-CRM is compared with the immunogenicity of a single dose of the licensed ACWY polysaccharide vaccine, in terms of the number of subjects with hSBA (human Serum Bacterial Activity) Geometric Mean Titers (GMTs) response against N. meningitidis serogroups A, C, W-135, and Y.

Seroresponse: For a subject with hSBA <1:4 at baseline, seroresponse is defined as a postvaccination hSBA ≥ 1:8; for a subject with hSBA ≥ 1:4 at baseline, seroresponse is defined as a postvaccination hSBA titer of at least 4 times the baseline.
- GMTs (hSBA) in Healthy Children 2 to 5 Years of Age (2 Doses v/s 1 Dose) [ Time Frame: 1 month postvaccination ]
The immunogenicity of two doses of the Novartis MenACWY-CRM vaccine, administered 2 months apart, is compared with the immunogenicity of a single dose of the Novartis MenACWY-CRM vaccine, in terms of hSBA (human Serum Bactericidal Activity) GMTs (Geometric Mean Titers) against N. meningitidis serogroups A, C, W-135, and Y.
ANOVA model used for the analysis of this outcome is different compare to ANOVA model used for the other outcome. The computed model components vary according to the variance observed due to the different datasets.
- Percentages of Subjects With at Least One Reactogenicity Sign After Vaccination in Children 2 to 5 Years of Age - 1 Dose Vaccine Treatment. [ Time Frame: Study days 1 to 7 ]Safety was assessed in terms of the percentages of subjects with reported local and systemic reactions up to 7 days after each vaccination per vaccination group, after 1 dose treatment.
- Percentages of Subjects With at Least One Reactogenicity Sign After Vaccination in Children 6 to 10 Years of Age - 1 Dose Vaccine Treatment. [ Time Frame: Study days 1 to 7 ]Safety was assessed in terms of the percentages of subjects with reported local and systemic reactions up to 7 days after each vaccination per vaccination group after 1 dose treatment.
- Percentages of Subjects With Unsolicited AEs Occurring Throughout the Study in Children Aged 2 to 10 Years - 1 Dose Vaccine Treatment. [ Time Frame: day 1 to study termination (day 240) ]Safety was assessed in terms of the percentage of subjects with unsolicited AEs occurring throughout the entire study period, after 1 dose treatment.
