Vaccination Course in Primed Children and Age-matched Unprimed Children With Pneumococcal Vaccine GSK1024850A

Summary

The purpose of this study is to assess the immune memory induced by primary and booster vaccination with pneumococcal conjugate vaccine GSK1024850A in the first year of life through evaluation of the immune responses following vaccination with a booster dose of pneumococcal conjugate vaccine GSK1024850A in the fourth year of life and to assess immune responses following vaccination with a single dose of pneumococcal conjugate vaccine GSK1024850A in age-matched unprimed children. The study also aims to assess the antibody persistence in the fourth year of life following primary and booster vaccination with pneumococcal conjugate vaccine GSK1024850A in the first year of life. The study is also designed to evaluate the immunogenicity in terms of antibody response and the safety/reactogenicity in terms of solicited and unsolicited symptoms and serious adverse events following a 2-dose vaccination with pneumococcal conjugate vaccine GSK1024850A in the fourth year of life. 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 = 00307034)
