ListOutcomeTime frameDescription
PrimaryGroups 1a and 2a: Percentage of Participants With Vaccine Seroresponse Measured by Serum Bactericidal Assay Using Human Complement (hSBA) at Day 30 Post 12-Month VaccinationDay 30 post 12-month vaccination (Month 13)
Functional meningococcal antibody activity against serogroups A, C, Y, and W were measured in a serum bactericidal assay utilizing the hSBA. Vaccine seroresponse was defined as a post 4th dose (Day 30 after 12-month) hSBA titer \>=1:16 for participants with pre 1st dose (Day 0 before 2-month) hSBA titer less than (\<) 1:8, or at least a 4-fold increase in hSBA titer from pre-vaccination to post-vaccination for participants with pre-vaccination hSBA titer \>=1:8. Percentages are rounded off to the tenth decimal place.
PrimaryGroups 1 and 2: Percentage of Participants Who Achieved Antibody Titers >=1:8 by hSBA at Day 30 Post 6-Month VaccinationDay 30 post 6-month vaccination (Month 7)Functional meningococcal antibody activity against serogroups A, C, Y, and W were measured in a serum bactericidal assay utilizing the hSBA. Percentages are rounded off to the tenth decimal place.
SecondaryGroups 1 and 2: Percentage of Participants Who Achieved Anti-Hepatitis B Antibody Concentrations >=10 Milli-International Units Per Milliliter (mIU/mL) at Day 30 Post 6-Month VaccinationDay 30 post 6-month vaccination (Month 7)
Anti-Hepatitis B surface antibodies (HBsAg) were measured by the commercially available VITROS ECi/ECiQ immunodiagnostic system using chemiluminescence detection technology. The percentage of participants with an anti-HBsAg antibody titer \>=10 mIU/mL was assessed. Percentages are rounded off to the tenth decimal place.
SecondaryGroups 1 and 2: Percentage of Participants Who Achieved Anti-Polyribosyl-Ribitol (PRP) Antibody Concentrations >=0.15 and >=1.0 Microgram (mcg)/mL at Day 30 Post 6-Month VaccinationDay 30 post 6-month vaccination (Month 7)
Anti-PRP concentrations were measured using a farr-type radioimmunoassay (RIA). The percentage of participants with an PRP antibody titer \>=0.15 mcg/mL and \>=1.0 mcg/mL were assessed. Percentages are rounded off to the tenth decimal place.
SecondaryGroups 1 and 2: Percentage of Participants Who Achieved Anti-Poliovirus Antibody Titers >=1:8 at Day 30 Post 6-Month VaccinationDay 30 post 6-month vaccination (Month 7)Anti-poliovirus types 1, 2, and 3 were measured by neutralization assay. The percentage of participants with anti-polio antibody titers \>=1:8 were assessed.
SecondaryGroups 1 and 2: Percentage of Participants Who Achieved Anti-Rotavirus Immunoglobulin A (IgA) Antibody Concentrations >=3-Fold Rise at Day 30 Post 6-Month VaccinationDay 30 post 6-month vaccination (Month 7)
Anti-rotavirus IgA antibodies in human serum were measured by enzyme-linked immunosorbent assay (ELISA). The percentage of participants who achieved anti-rotavirus IgA Ab concentrations \>=3-fold rise were assessed. Percentages are rounded off to the tenth decimal place.
SecondaryGroups 1 and 2: Geometric Mean Concentrations (GMCs) of Anti-Rotavirus IgA Antibodies at Day 30 Post 6-Month VaccinationDay 30 post 6-month vaccination (Month 7)GMCs of anti-rotavirus serum IgA antibodies were assessed using ELISA.
SecondaryGroups 1 and 2: GMCs of Anti-Pertussis Antibodies at Day 30 Post 6-Month VaccinationDay 30 post 6-month vaccination (Month 7)
GMCs of anti-pertussis antibodies (pertussis toxoid \[PT\], filamentous hemagglutinin adhesin \[FHA\], pertactin \[PRN\] and fimbriae types 2 and 3 \[FIM\]) were measured by electrochemiluminescent (ECL) assay.
SecondaryGroups 1 and 2: GMCs of Anti-Pneumococcal Antibodies at Day 30 Post 6-Month VaccinationDay 30 post 6-month vaccination (Month 7)
GMCs of anti-pneumococcal antibodies was assessed by pneumococcal capsular polysaccharide (PnPS) IgG ECL assay which is used to quantitate the amount of anti-streptococcus pneumoniae PS (serotypes 1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F and 23F) antibodies in human serum.
SecondaryGroups 1a and 2a: Percentage of Participants Who Achieved Vaccine Response for Measles, Mumps and Rubella (MMR) Antibodies at Day 30 Post 12-Month VaccinationDay 30 post 12-month vaccination (Month 13)
Vaccine response against anti-measles and anti-rubella antibodies were measured by bulk IgG enzyme immunoassay and anti-mumps antibodies were assessed by ELISA. Percentage of participants with anti-measles, anti-mumps, anti-rubella antibody concentration that met the respective mentioned criterion are reported: measles: \>=255 mIU/mL; mumps: \>=10 antibody units per milliliter and rubella: \>=10 IU/mL. Percentages are rounded off to the tenth decimal place.
