Immunogenicity and Safety of V419 (PR51) in Combination With MCC in Infants and Toddlers (V419-011)

MCM Vaccines B.V.284 enrolled

Overview

The primary objectives of this study are to evaluate the immunogenicity and safety of concomitant administration of V419 (PR51) with 2 types of meningococcal serogroup C conjugate (MCC) vaccines to healthy infants at 3 and 4 months of age in terms of antibody seroprotection rate (SPR) to MCC. Participants also received a Haemophilus influenza type B (Hib)-MCC vaccination at 12 months of age. It was hypothesized that the SPR to MCC at 1 month post-dose 2 of either tetanus toxoid conjugated Meningo C (MCC-TT) or CRM197 conjugated Meningo C (MCC-CRM) vaccines would be acceptable when administered concomitantly with V419.
