Official Title: Immunogenicity and Safety of Meningococcal (Groups A, C, Y, and W-135) Diphtheria Toxoid Conjugate Vaccine (Menactra®) in Adolescents in the US When Administered Concomitantly With Tetanus Toxoid
Brief Summary:
The purpose of this study was to evaluate the immunogenicity and safety of the concomitant administration of Menactra® vaccine and Tdap vaccine in adolescents aged 11 to 17 years.
Primary Objective:
To determine whether concomitant administration of two vaccines, Tdap and Menactra®, induces antibody responses that are similar to those observed when each vaccine is given separately.
Secondary Objective:
To compare the rates of injection site reactions at the Tdap injection site after Tdap and Menactra® vaccines are administered concomitantly to the corresponding rates of reactions when Tdap vaccine is administered alone.
