Concentrations of Antibodies Against Vaccine Pneumococcal Serotypes (Booster Immunization)
Antibodies assessed for this outcome measure were those against the vaccine pneumococcal serotypes 1, 4, 5, 6B, 7F, 9V, 14, 18C, 19F and 23F (ANTI-1, -4, -5, -6B, -7F, -9V, -14, -18C, -19F and -23F). Antibody concentrations were measured by 22F ELISA, expressed as GMCs, in μg/mL. The seropositivity cut-off of the assay was an antibody concentration ≥ 0.05 μg/mL. Antibody concentrations < 0.05 μg/mL were given an arbitrary value of half the cut-off for the purpose of GMC calculation.
Administration of catch-up pneumococcal vaccination with a licensed product other than Synflorix was allowed in the DTPa Group at least 7 days before DTPa vaccine booster dose. Thus, for this booster phase analysis, the DTPa Group was further split in DTPa + Prevenar Group and DTPa - no Prevenar Group.

Concentrations of Antibodies Against Protein D (PD) (Primary Immunization)
Anti-protein D (Anti-PD) antibody concentrations by Enzyme-Linked Immunosorbent Assay (ELISA) were calculated, expressed as geometric mean concentrations (GMCs) in ELISA unit per milli-liter (EL.U/mL) and tabulated.
