Meningitis Clinical Trial
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 Menomune® or Menactra®
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.
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. ;
Allocation: Non-Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Open Label, Primary Purpose: Prevention
