Study of Long-term Antibody Persistence After a Booster Dose of Menitorix Vaccine

Summary

The purpose of this study is to evaluate the long-term antibody persistence at 12, 24 and 48 months after the administration of a booster dose of Menitorix™, given at 12-15 months of age. The children had previously received 3 doses of Menitorix™ and Infanrix IPV™ or Meningitec™ and Pediacel™ in infancy. In addition, the antibody persistence is to be investigated in children of 40-43 months of age who received a 3-dose primary vaccination of a MenC conjugate vaccine and a Hib containing vaccine in infancy without a booster dose of MenC conjugate and Hib vaccine in the second year of life. This protocol posting deals with objectives \& outcome measures of the extension phases at 12, 24 and 48 months after the booster phase. The links to objectives and outcome measures of the primary phase \& booster phase at 12 to 15 months are provided below: https://www.gsk-studyregister.com/study/2747 (Primary phase) https://www.gsk-studyregister.com/study/2755 (Booster phase)
