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.

Time frame: 1 month postvaccination
