Outcome

Type Measure Description Time frame Safety issue
Primary Number of Seroprotected Subjects Against Anti-diphtheria (Anti-D) and Anti-tetanus (Anti-T). A seroprotected subject is a subject with anti-D/anti-T antibody concentrations greater than (=) or equal to 0.1 international units per milliliter (IU/mL) At Day 0
Primary Concentrations of Antibodies Against Anti-D and Anti-T Concentrations are presented as geometric mean concentrations (GMCs), expressed in milliinternational units per millilitre (mIU/mL). At Day 0
Primary Number of Subjects With Anti-pertussis Toxoid (Anti-PT), Antifilamentous Haemagglutinin (Anti-FHA) and Anti-pertactin (Anti-PRN) Antibody Concentrations =5 ELISA Units Per Milliliter (EL.U/mL). Cut-off values assessed were greater than or equal to 5 ELISA units per millilitre (EL.U/mL) in the sera of subjects seronegative before vaccination. At Day 0
Primary Concentrations of Antibodies Against Anti-PT, Anti-FHA and Anti-PRN. Concentrations are presented as geometric mean concentrations (GMCs), expressed in ELISA units per millilitre (EL.U/mL). At Day 0
Primary Number of Seroprotected Subjects Against Anti-hepatitis B Surface Antigen (Anti-HBs). Seroprotection = anti-HBs antibody concentration = 10 milli-international units per milliliter (mIU/mL). At Day 0
Primary Concentrations of Antibodies Against Anti-HBs. Concentrations are presented as geometric mean concentrations (GMCs), expressed in milliinternational units per millilitre (mIU/mL). At Day 0
Primary Number of Seroprotected Subjects Against Anti-polyribosyl Ribitol Phosphate (Anti-PRP). A seroprotected subject is a subject with anti-PRP antibody concentrations = 0.15 micrograms per milliliter (µg/mL) At Day 0
Primary Concentrations of Antibodies Against Anti-PRP. Concentrations are presented as geometric mean concentrations (GMCs), expressed in micrograms per millilitre (µg/mL). At Day 0
Primary Number of Subjects With Serious Adverse Events (SAEs). Assessed SAEs include medical occurrences that result in death, are life-threatening, require hospitalization or prolongation of hospitalization or result in disability/incapacity. During the entire study period (up to Day 46)
Primary Number of Subjects With Anti-HBs Antibody Concentrations = 6.2 mIU/mL Cut-off values assessed were greater than or equal to 6.2 milliinternational units per millilitre ( mIU/mL) in the sera of subjects seronegative before vaccination. At Day 0
