Study Endpoints

Primary Endpoints

Number of Seroprotected Subjects Against Pneumococcal Serotypes
One month post-dose 2 (Month 3) administration of Synflorix™ vaccine

A seroprotected subject was defined as a subject who had anti-pneumococcal serotypes antibody concentrations greater than or equal to (≥) the threshold value of 0.20 micrograms per milliliter (μg/mL). The vaccine pneumococcal serotypes assessed were 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 enzyme-linked immunosorbent assay (ELISA), expressed as geometric mean concentrations (GMCs). The results presented for the Group 1 correspond to the primary outcome.

Secondary Endpoints

Number of Seroprotected Subjects Against Pneumococcal Serotypes
One month before (Month 9) and one month after (Month 10) the booster dose of Synflorix™ vaccine
Antibody Concentrations Against Pneumococcal Serotypes
One month post-dose 2 or post-dose 3 (Month 3) administration, one month before (Month 9) and one month after (Month 10) the booster dose of Synflorix™ vaccine
Opsonophagocytic Activity Against Vaccine Pneumococcal Serotypes
One month post-dose 2 or post-dose 3 (Month 3) administration, one month before (Month 9) and one month after (Month 10) the booster dose of Synflorix™ vaccine
