Brief summary

The primary phase of this study is evaluating the safety 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. This protocol posting deals with objectives & outcome measures of the primary phase of the study. The objectives & outcome measures of the Booster phase are presented in a separate protocol posting (NCT number = 00345683). The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep 2007

Detailed description

Pediarix/Infanrix Penta and Prevnar should be co-administered to all subjects in all study groups according to a 2, 4, and 6 month schedule concomitantly with study vaccines.
