Primary Outcome Measures

Name	Time	Method
Percentage of Subjects With hSBA ≥1:8	At 40 and 60 months of age	Percentages of subjects with human Serum Bactericidal Assay (hSBA) ≥1:8 as measured by serum bactericidal activity at 40 months and 60 months of age and associated 95% Clopper-Pearson CIs were computed for each of the serogroups within each of the vaccinated groups and in age-matched control subjects.

Secondary Outcome Measures

Name	Time	Method
Percentage of Subjects With hSBA ≥1:4	At 40 and 60 months of age	Percentages of subjects with hSBA ≥1:4 as measured by serum bactericidal activity at 40 months and 60 months of age and associated 95% Clopper-Pearson CIs were computed for each of the serogroups within each of the vaccinated groups and in age-matched control subjects.
GMTs in Subjects Within Each Site and in Age-Matched Control Subjects	At 40 and 60 months of age	The Geometric Mean Titers (GMTs) as measured by serum bactericidal activity at 40 months and 60 months of age and 95% CIs were calculated for each vaccine group and for each serogroup by exponentiating (base 10) the least square means of the logarithmically transformed (base 10) titers and their 95% CIs obtained from a two-way Analysis of Variance (ANOVA) with factors for vaccine group and center.
