- Primary Outcome Measures
Name Time Method Primary Outcome Measure:<br>1. Seroresponse Percentage of subjects with seroresponse, measured by rabbit complement serum bactericidal activity (rSBA) against serogroups A, C, Y, W and X. [Seroresponse is defined as a post-immunization (Day 29) rSBA titer of 32 or greater if the subject’s pre-immunization (Day 1) rSBA titer was < 8; or a = four-fold increase over baseline at Day 29 postimmunization if the subject’s pre-immunization (Day 1) rSBA titer was = 8].<br>2. Geometric mean titres Geometric mean titers (GMTs) measured by rSBA against serogroups A, C, Y, W and X on Day 29
