An Efficacy Study of GlaxoSmithKline (GSK) Biologicals' Candidate Influenza Vaccine GSK2321138A in Children

Summary

The purpose of this study is to evaluate the efficacy, immunogenicity and safety of GSK Biologicals' influenza candidate vaccine GSK2321138A when compared to non-influenza vaccine comparators in children 6 to 35 months of age. Recruitment will encompass at least 4 independent cohorts: a first cohort in the Northern Hemisphere (2011-2012), a second cohort in subtropical countries (2012), third cohort in the Northern Hemisphere (2012-2013) and a fourth cohort and additional independent cohorts possibly in NH countries (end 2013) and subtropical countries (beginning 2014).
