Clinical Trial: Study of a Booster Dose of Meningococcal Diphtheria Toxoid Conjugate Vaccine in Adolescents
Study Status: Completed
Recruit Status: Completed
Study Type: Interventional
Official Title: Antibody Responses to a Booster Dose of an Experimental Tetravalent (A, C, Y, and W-135) Meningococcal Diphtheria Toxoid Conjugate Vaccine, Menactra® in Adolescents Who Previously Received Menomu
Brief Summary:
This study was designed to evaluate the antibody response to a Menactra® booster dose in participants who previously received one dose of Menactra® or Menomune® as adolescents 3 years earlier in Study MTA02.
Primary Objective:
To evaluate the antibody responses to a booster dose of a tetravalent meningococcal diphtheria toxoid conjugate vaccine (Menactra®) in participants who had previously received Menactra® or Menomune® as adolescents in the MTA02 Study and antibody responses to a dose of Menactra® in naive adolescents.
Detailed Summary: All subjects were given a single boosting dose of Menactra® to evaluate the kinetics of the response, the magnitude and the avidity of the antibody produced.
