Immunogenicity and Safety Study of an Investigational Quadrivalent Meningococcal Conjugate Vaccine When Administered Concomitantly With Routine Pediatric Vaccines in Healthy Infants and Toddlers in Europe
Primary objective is to demonstrate the non-inferiority of the antibody response against meningococcal serogroups A, C, Y, and W following the administration of a 3-dose series of MenACYW conjugate vaccine compared to a 3-dose series of a licensed meningococcal vaccine when each vaccine is given concomitantly with routine pediatric vaccines (10-valent pneumococcal vaccine and diphtheria, tetanus, pertussis, hepatitis B, poliomyelitis and Haemophilus influenzae type b [DTaP-IPV-HB-Hib vaccine]) to infants and toddlers 6 weeks to 18 months old Secondary objectives are: To demonstrate the non-inferiority of the antibody (Ab) response against meningococcal serogroups A, C, Y, and W following the administration of 2 doses in infancy of MenACYW conjugate vaccine compared to 2 doses of a licensed meningococcal vaccine when each vaccine is given concomitantly with routine pediatric vaccines (10-valent pneumococcal vaccine and DTaP-IPV-HB-Hib vaccine) to infants and toddlers 6 weeks to 18 months old. To describe the Ab responses against meningococcal groups A, C, Y, and W and the antigens of the routine pediatric vaccines administered in the study.
