The Long-term Antibody Persistence of GSK Biologicals' Meningococcal Vaccine GSK134612 in Healthy Adolescents/Adults

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 and Menactra® in a previous study (whose objectives \& outcome measures are presented in a separate protocol posting with NCT number =00454909) will be evaluated. The safety and immune response to a booster dose of vaccine GSK134612 administered at 5 years post-primary vaccination and a primary vaccination of a newly enrolled group with GSK 134612 vaccine will also be evaluated.
