Brief summary

The purpose of this study is to evaluate the safety, reactogenicity and immunogenicity of a booster dose of GlaxoSmithKline (GSK) Biologicals´ pneumococcal conjugate vaccine co-administered with a booster dose of DTPa-IPV/Hib (Infanrix-IPV/Hib) in preterm born children at the age of 16-18 months. This protocol posting deals with objectives & outcome measures of the booster phase. The objectives & outcome measures of the primary phase are presented in a separate protocol posting (NCT number =NCT00390910 ). Subjects participating in this study should have received three doses of pneumococcal vaccine in the primary study. The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep 2007.

Antibody Concentrations Against Anti-polyribosyl-ribitol-phosphate (Anti-PRP)

Seropositivity status was defined as the anti-polyribosyl-ribitol-phosphate (Anti-PRP) antibody concentrations greater than or equal to (≥) 0.15 micrograms per milliliter (µg /mL) and ≥ 1.0 µg/mL. Antibody concentrations were measured by enzyme-linked immunosorbent assay (ELISA), presented as geometric mean concentrations (GMCs).

Time frame: Prior to (Pre-booster) and one month after (Post-booster) the administration of the booster dose of Synflorix™ vaccine co-administered with the booster dose of Infanrix™ -IPV/Hib vaccine

Population: The analysis was performed on the ATP cohort for immunogenicity, which included all evaluable subjects for whom assay results were available for antibodies against at least one study vaccine antigen component after vaccination.

Number of Seropositive Subjects for Opsonophagocytic Activity (OPA) Against Pneumococcal Cross-reactive Serotypes 6A and 19A

A seropositive subject was defined as a subject with opsonophagocytic activity against pneumococcal cross-reactive serotypes 6A and 19A greater than or equal to (≥) the cut-off value of 8.

Time frame: One month after (Post-booster) the administration of the booster dose of Synflorix™ vaccine co-administered with the booster dose of Infanrix™-IPV/Hib vaccine

Population: The analysis was performed on the ATP cohort for immunogenicity, which included all evaluable subjects for whom assay results were available for antibodies against at least one study vaccine antigen component after vaccination.
