Outcomes

Primary Outcomes

Anti-Meningitis Antibody Titers by Serum Bactericidal Assay Using Rabbit Complement (rSBA)

The analysis was performed for the serogroups -MenA, -MenC -MenW-135 and -MenY. Antibody titers tabulated as geometric mean titers (GMTs), were obtained by serum bactericidal assay using rabbit complement and expressed in enzyme-linked immunosorbent assay (ELISA) units per milliliter (EL.U/mL). The primary outcome results only refer to Nimenrix+Boostrix Group and Nimenrix Group.

Time frame: One month after Nimenrix vaccination (i.e. Month 1 for Nimenrix+Boostrix and Nimenrix Groups and Month 2 for Boostrix Group)

Number of Subjects With Anti-D and Anti-T Concentrations Above the Cut-off Value

The antibody concentrations were calculated as geometric mean concentrations (GMCs) and expressed as international units per milliliter (IU/mL). The reference cut-off value was an antibody concentration ≥ 1 IU/mL. The primary outcome results only refer to Nimenrix+Boostrix Group and Boostrix Group.

Time frame: One month after Boostrix vaccination (i.e. Month 1)

Anti-pertussis Toxoid (Anti-PT), Anti-filamentous Haemagglutinin (Anti-FHA) and Anti-pertactin (Anti-PRN) Antibody Concentrations

The antibody concentrations were tabulated as adjusted geometric mean concentrations (GMCs) and expressed as international units per millilitre (IU/mL). The primary outcome results only refer to Nimenrix+Boostrix Group and Boostrix Group

Time frame: One month after Boostrix vaccination (i.e. Month 1)

Secondary Outcomes

Number of Subjects With rSBA-MenA, rSBA-MenC, rSBA-MenW-135 and rSBA-MenY Antibody Titres Above the Cut-off Values

The reference cut-off values of the assay were rSBA-Men antibody concentrations ≥ 1:128 and ≥ 1:8.

Time frame: Prior to (i.e. Month 0 for Nimenrix+Boostrix and Nimenrix Groups and Month 1 for Boostrix Group) and one month after Nimenrix vaccination (i.e. Month 1 for Nimenrix+Boostrix and Nimenrix Groups and Month 2 for Boostrix Group)
