Primary Outcome Measures
NameTimeMethod
Geometric Mean Titer of the Meningococcal B Vaccine Against the Different Strains at One Month After First, Second and Third Vaccination.One month after vaccinations

Geometric mean titers(GMT) and the respective confidence intervals measured after each vaccination against the three different meningococcal strains.

Percentages of Participants With Serum Bactericidal Activity of the Meningococcal B Vaccine Against Different Strains at One Month After First, Second and Third Vaccination.One month after vaccinations

Percentage of participants with serum bactericidal activity (SBA) of the Meningococcal ACWY vaccine at one month after vaccination against A, C, W-135 and Y strains. Bactericidal activity (% ≥ 1:4, i.e., percentage of subjects with BCA titer ≥ 1:4; % ≥ 1:8, i.e. percentage of subjects with BCA titer ≥ 1:8) against a panel of genetically distinct meningococcal B strains:

* prior to the first vaccination

* 30 days following the first, second, prior to the third and 30 days after the third vaccination

Geometric Mean Titer (GMT) of the Meningococcal ACWY Vaccine at One Month After Vaccination.One month after vaccinations

Geometric mean titer (GMT) of the Meningococcal ACWY Vaccine at One Month After the Immunization against the A, C, W-135 and Y strains.

Percentage of Participants With Serum Bactericidal Activity of the Meningococcal ACWY Vaccine at One Month After VaccinationOne month after vaccinations

Percentage of participants with serum bactericidal activity (SBA) of the Meningococcal ACWY vaccine at one month after vaccination against A, C, W-135 and Y strains. Bactericidal activity (% ≥ 1:4, i.e., percentage of subjects with BCA titer ≥ 1:4; % ≥ 1:8, i.e. percentage of subjects with BCA titer ≥ 1:8) against a panel of genetically distinct meningococcal B strains:

* prior to the first vaccination

* 30 days following the first, second, prior to the third and 30 days after the third vaccination

Number of Subjects Who Reported Solicited Local and Systemic Reactions Post Vaccination.One month after vaccinations

The number of subjects who reported solicited reactions after the administration of the Meningococcal B vaccine at a 0, 2, 6-month schedule and the administration of the Meningococcal A, C, W, and Y vaccine at month 7.
