Primary Outcome Measures
NameTimeMethod
Percentages of Subjects With hSBA Seroresponse, in Healthy Children 6 to 10 Years of Age.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.

Percentages of Subjects With hSBA Seroresponse, in Healthy Children 2 to 5 Years of Age1 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.

Secondary Outcome Measures
NameTimeMethod
Percentages of Subjects With hSBA Seroresponse, in Healthy Children 2 to 5 Years of Age (2 Doses vs 1 Dose)1 month postvaccination

The immunogenicity of two doses of the Novartis MenACWY-CRM, administered 2 months apart, is compared with the immunogenicity of a single dose of the Novartis MenACWY-CRM, 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 Unsolicited AEs Occurring Throughout the Study in Children Aged 2 to 10 Years - 1 Dose Vaccine Treatment.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.

Percentages of Subjects With at Least One Reactogenicity Sign After Vaccination in Children 6 to 10 Years of Age - 1 Dose Vaccine Treatment.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.

Geometric Mean Titers (hSBA), in Healthy Children 2 to 10 Years of Age.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.
