Phase 2
Completed
Conditions
Infections, Meningococcal
Registration Number

Lead Sponsor
GlaxoSmithKline
Brief Summary

The purpose of this booster vaccination study is to evaluate the persistence and immune memory induced by a three-dose primary vaccination course with GSK Biologicals' MenC-TT (Neisseria meningitidis group C polysaccharide-tetanus toxoid) and GSK Biologicals' Hib-MenC-TT (Haemophilus influenzae type b-MenC-TT) or Meningitec™ vaccines in healthy toddlers aged 12-15 months by giving them a 1/5th dose of Mencevax™ ACWY.

Detailed Description

The study is an extension of the primary vaccination study 711202/001 (MenC-TT-001). It comprises 5 groups: 4 parallel groups of toddlers vaccinated in study 711202/001 (group vaccinated with Meningitec™ is control group 1) and 1 group of naive subjects (no previous vaccination against MenC disease, control group 2). All subjects receive 1/5th dose Mencevax™ ACWY and a concomitant dose of Infanrix hexa®. 2 blood samples: prior to and 1 month after vaccination.
