Primary Outcome Measures
NameTimeMethod
Percentage of Subjects With hSBA ≥1:8At 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
NameTimeMethod
Percentage of Subjects With hSBA ≥1:4At 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 SubjectsAt 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.
