Co-administration of Meningococcal Vaccine GSK134612 and Pneumococcal Vaccine GSK1024850A vs Individual Administration

Phase 3

Completed

Conditions: Infections, Meningococcal

Interventions: Biological: Meningococcal vaccine GSK134612
Biological: Pneumococcal vaccine GSK1024850A

Registration Number: NCT00758264

Lead Sponsor: GlaxoSmithKline

Brief Summary: The purpose of this study is to demonstrate, in 12-23 months old subjects, the non-inferiority of meningococcal vaccine GSK134612 and pneumococcal vaccine GSK1024850A when co-administered, compared to each vaccine administered individually.

Detailed Description: Multi-center study with 3 parallel groups. One group will receive 2 vaccines injections at the same visit (pneumococcal+ meningococcal), one group will receive a pneumococcal vaccine followed one month later by a meningococcal vaccine, and the last group will receive the meningococcal vaccine followed one month later by the pneumococcal vaccine.

All subjects will have one blood sample taken before vaccination and one blood sample taken one month after each vaccination (i.e. the first group will have 2 blood samples taken, and the other two groups will have 3 blood sample taken)
