End point title |
1. Percentage of Overall Subjects With Seroresponse, Directed Against Neisseria meningitidis Serogroups A, C, W and Y After MenACWY-CRM Vaccination. [1] | ||||||||||||||||
End point description |
Immunogenicity was measured as the percentage of subjects with human serum bactericidal assay (hSBA) seroresponse and associated 95% Clopper-Pearson confidence interval (CI), directed against N. meningitidis serogroups A, C, W and Y, evaluated by serum bactericidal assay using human complement (hSBA), at 28 days after one vaccination of MenACWY-CRM (day 29).
Seroresponse is defined as:
a. for subjects with a prevaccination hSBA titer <1:4, a postvaccination hSBA titer ≥1:8.
b. for subjects with a prevaccination hSBA titer ≥1:4, an increase in hSBA titer of at least four times the prevaccination titer.
Analysis was done on modified intention-to-treat (MITT) population.
