1.Primary Outcome
Title Percentage of Overall Subjects With Seroresponse, Directed Against Neisseria Meningitidis Serogroups A, C, W and Y After MenACWY-CRM Vaccination
Hide Description

Immunogenicity was measured as the percentage of subjects with 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:

  1. for subjects with a prevaccination hSBA titer <1:4, a postvaccination hSBA titer ≥1:8.
  2. for subjects with a prevaccination hSBA titer ≥1:4, an increase in hSBA titer of at least four times the prevaccination titer.
Time Frame Day 1 and Day 29
Hide Outcome Measure Data
Hide Analysis Population Description
Analysis was done on modified intention-to-treat (MITT) population i.e subjects in the exposed population who provided evaluable serum samples whose assay results were available for at least one serogroup on day 1 and/or day 29.
