Outcome Measures
Primary Outcomes (1)
Percentage of Subjects Without Bactericidal Activity at 1:4 Dilution Against Each US Neisseria Meningitidis (N. Meningitidis) Serogroup B Strain at One Month After the Second Vaccination.
The combined percentage of subjects without bactericidal activity at 1:4 dilution using the endogenous complement human Serum Bactericidal Assay (enc-hSBA) across all strains in MenABCWY group and MenACWY group is reported at one month after the second injection. The percentage of subjects without bactericidal activity at 1:4 dilution was used to assess the effectiveness of two doses of MenABCWY vaccine when compared to one dose of Men ACWY vaccine against a panel of US N. meningitidis serogroup B invasive disease strains. Least Square (LS)-mean computed from the generalized linear model.
One month after the second vaccination (month 3)
Secondary Outcomes (27)
Percentages of Subjects Without Bactericidal Activity at 1:4 Dilution Against Each US N. Meningitidis Serogroup B Strain at 4 Months After the Second Vaccination.
Four months after the second vaccination (month 6)
Percentages of Subjects Without Bactericidal Activity at 1:8 Dilution Against Each US N. Meningitidis Serogroup B Strain at One Month After the Second Vaccination
One month after the second vaccination (month 3)
Percentages of Subjects Without Bactericidal Activity at 1:8 Dilution Against Each US N. Meningitidis Serogroup B Strain at Four Months After the Second Vaccination.
Four months after the second vaccination (month 6)
Percentages of N. Meningitidis Serogroup B Invasive Disease Strains Killed at 1:4 and 1:8 Dilutions, for Each Subject
Baseline, one month after second vaccination (month 3)
Percentages of N. Meningitidis Serogroup B Invasive Disease Strains Killed at 1:4 and 1:8 Dilutions, for Each Subject
Baseline, four months after second vaccination (month 6)
