The primary aim of the study is to demonstrate that an investigational 4-dose presentation of the 10Pn-PD-DiT vaccine with preservative is non-inferior to the licensed presentation of Synflorix (preservative-free) in terms of immune responses to the 10 vaccine pneumococcal serotypes (primary objective) and to the vaccine-related pneumococcal serotype 19A (first secondary objective), after administration of a 3-dose primary vaccination course at 6, 10 and 18 weeks of age co-administered with the first 2 doses of DTPw-HBV/Hib vaccine given at 6, 10 and 14 weeks of age (according to the Expanded Program on Immunization (EPI) schedule). In addition, the study will also assess the safety, reactogenicity, immunogenicity and antibody persistence (approximately 7 months following primary vaccination) of the 4-dose presentation of the 10Pn-PD-DiT vaccine given as primary vaccination schedule at 6, 10 and 18 weeks of age followed by a booster dose at 38 weeks. This study also aims at assessing the safety, reactogenicity and immunogenicity of the 4-dose presentation of the 10Pn-PD-DiT vaccine when given as a booster dose at approximately 9 months of age.

Antibody Concentrations Against Pneumococcal Serotypes (Epoch 001)
Antibodies assessed for this outcome measure were those against the vaccine/cross-reactive pneumococcal serotypes 1, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F and 23F (ANTI-1, -4, -5, -6A, -6B, -7F, -9V, -14, -18C, -19A, -19F and -23F). Antibody concentrations were measured by 22F-inhibition enzyme-linked immunosorbent assay (ELISA), expressed as geometric mean concentrations (GMCs), in micrograms per milliliter (µg/mL). The cut-off of the assay was an antibody concentration higher than or equal to (≥) 0.05 µg/mL. Primary outcome results correspond to antibody concentrations for the 10 vaccine serotypes 1, 4, 5, 6B, 7F, 9V, 14, 18C, 19F and 23F.
