Clinical Trial Summary

The purpose of the primary phase of the study is to demonstrate the non-inferiority of a single dose of GSK Biologicals' Haemophilus influenzae type b and meningococcal C (Hib-MenC) conjugate vaccine when given in the second year of life to subjects primed in infancy with a Hib vaccine, but not with a meningococcal serogroup C vaccine, versus commercially available Hib and MenC vaccines.

In the extension phase, at Years 1, 2, 3, 4 & 5, one blood sample is taken at each year to follow the antibody persistence up to 5 years after vaccination. No additional vaccine is administered during the extension phase. The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep 2007.

Description:

This multicenter study is open and has 2 treatment groups with Hiberix™ + a commercially available MenC vaccine as active controls. Priorix™ is given concomitantly in both groups. In the primary phase, two blood samples are taken from all subjects for immunogenicity analyses: before and one month after vaccination. In the extension phase, at Year 1, 2, 3, 4 & 5, one blood sample is taken at each year to follow the antibody persistence up to 5 years after vaccination. No additional vaccine is administered during the extension phase.
