The Long-term Antibody Persistence of GSK Biologicals' Meningococcal Vaccine GSK134612 in Healthy Toddlers

Summary

In this study, the concentration of antibody to the vaccine one year, three and five years after vaccination in subjects who were vaccinated with GSK Biologicals' meningococcal vaccine GSK134612 in a previous study (whose objectives \& outcome measures are presented in a separate protocol posting with NCT number =00471081) will be evaluated. The safety and immune response of a booster dose of vaccine GSK134612 administered at 5 years post-primary vaccination will also be evaluated. In addition, the immune response to a dose of vaccine GSK134612 administered to age-matched controls not previously given a meningococcal vaccine will be evaluated. This protocol posting has been updated further to protocol amendment 2, dated 28 october 2010. The sections impacted are summary, study design, outcome measures, intervention, and eligibility criteria.
