Trial overview
Official title: Study to demonstrate non-inferiority of GSK Biologicals’ Hib-MenC with Priorix™, versus MenC-CRM197 vaccine with Hiberix™ & Priorix™ in toddlers primed with Hib but not MenC & to evaluate persistence up to 5 years after vaccination.
Trial description: 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.
