Summary

The primary objective of this study is to demonstrate the non-inferiority of the vaccine seroresponse to meningococcal serogroups A, C, Y, and W following administration of 2 doses of MenACYW conjugate vaccine compared to 2 doses of MENVEO when given concomitantly with routine pediatric vaccines to infants and toddlers 6 to 7 months of age and 12 to 13 months of age.

The secondary objective is to demonstrate the non-inferiority of the percentage of subjects with antibody titers to meningococcal serogroups A, C, Y, and W 1:8 following administration of 2 doses of MenACYW conjugate vaccine compared to 2 doses of MENVEO when given concomitantly with pediatric routine vaccines to infants and toddlers at 6 to 7 months of age and 12 to 13 months of age.

The study also includes as an observational objective to describe the safety profile of MenACYW conjugate vaccine and MENVEO when administered concomitantly with routine pediatric vaccines in healthy infants and toddlers.

Description

Study duration per participant is approximately 1 year in Group 1 and Group 2, and 10 months in Group 3 and Group 4. This duration includes a safety follow-up contact at 6 months after the last vaccination.

Receipt of any vaccine in the 4 weeks preceding the first trial vaccination or planned receipt of any vaccine in the 4 weeks before and / or following any trial vaccination except for influenza vaccination, which may be received at least 2 weeks before or 2 weeks after any study vaccination. This exception includes monovalent pandemic influenza vaccines and multivalent influenza vaccines
Previous vaccination against meningococcal disease with either the trial vaccine or another vaccine (i.e., mono- or polyvalent, polysaccharide, or conjugate meningococcal vaccine containing serogroups A, C, Y, or W; or meningococcal B serogroup-containing vaccine)
For subjects to be enrolled at 6 to 7 months of age (Group 1 and Group 2), prior receipt of more than 2 doses of DTaP, Hib, IPV, pneumococcal, hepatitis B (for children who received hepatitis B at 2 and 4 months of age, prior receipt of more than 3 doses of hepatitis B vaccine) or rotavirus vaccine
