Title: An Open-label, Randomised, Comparative, Multi-centre Study of the Immunogenicity and Safety of the Concomitant Use of a Live Pentavalent Rotavirus Vaccine (RotaTeq®) and a Meningococcal Group C Conjugate (MCC) Vaccine in Healthy Infants
Brief Summary: Primary objective:

To check if RotaTeq® can be administered concomitantly with meningococcal Group C vaccine without impairing the efficacy of MCC vaccine. The hypothesis tested is that the seroprotection rate for MMC at 28 days after the second MCC vaccination with concomitant administration of RotaTeq® is non-inferior to that without non-concomitant (sequential) administration of RotaTeq®.
