Study of Antibody Responses After a Dose of Tetravalent Meningococcal Diphtheria Conjugate Vaccine in Children

Summary

The study investigated safety profile and the antibody responses to an experimental tetravalent meningococcal diphtheria conjugate vaccine (Menactra®) in children who have received a monovalent meningococcal C conjugate vaccine at least one year previously. Primary objective: To describe and compare the Serum Bactericidal Assay (SBA) antibody response for serogroup C in participants receiving Menactra® to the serogroup C antibody response in a control group of participants receiving a licensed Haemophilus Influenzae Type b (Hib) conjugate vaccine 28 days following vaccination.
