Safety, Reactogenicity and Immunogenicity Study of GSK Biologicals' Pneumococcal Vaccine GSK1024850A, Given Either as a Booster Dose or as a 2-dose Catch-up Immunization in Healthy Nigerian Children

The purpose of this trial is to assess the safety, reactogenicity and immunogenicity of GSK Biologicals' pneumococcal conjugate vaccine GSK1024850A when administered either as a booster dose or as a two dose catch-up vaccination in the second year of life to the Nigerian subjects previously enrolled in the primary vaccination study NCT00678301.

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 = NCT00678301).

Solicited general symptoms assessed were drowsiness, fever, irritability and loss of appetite.

Unsolicited AEs = Any AE reported in addition to those solicited during the clinical study. Also any "solicited" symptom with onset outside the specified period of follow-up for solicited symptoms was reported as an unsolicited adverse event.

Časové okno: Prior to and one month after the booster immunisation for the Synflorix/Infanrix primed Group and prior to the first dose and one month after Dose 2 in the Synflorix/Infanrix unprimed Group

Vaccine pneumococcal serotypes assessed were serotypes 1, 4, 5, 6B, 7F, 9V, 14, 18C, 19F and 23F.

Concentrations were expressed as geometric mean concentrations (GMCs) in microgram per millilitre (µg/mL).
