Dataset from A Phase III, Randomized, Multinational Study, Double-blinded for the Immunogenicity and Consistency Evaluation of 3 Hib-MenCY-TT Vaccine Lots and Single-blinded and Controlled for the Evaluation of Safety and Immunogenicity of GSK Biologicals' Haemophilus Influenzae Type b and Neisseria Meningitidis Serogroups C and Y-tetanus Toxoid Conjugate Vaccine Combined (Hib-MenCY-TT) Compared to Monovalent Hib Vaccine in Healthy Infants at 2, 4, 6, and 12 to 15 Months of Age.

This study evaluates the immunogenicity and consistency of 3 Hib-MenCY-TT vaccine lots and the safety and immunogenicity of Hib-MenCY-TT vaccine compared to a control group receiving licensed Hib conjugate vaccine, when each are co-administered with Pediarix® to healthy infants at 2, 4, and 6 months of age. The study will also evaluate the safety and immunogenicity of Hib-MenCY-TT vaccine compared to a control group receiving licensed Hib conjugate vaccine, when each are co-administered with M-M-R® II and Varivax® at 12 to 15 months of age.
