About

The study is designed to evaluate the persistence of bactericidal antibodies in subjects aged 7 to 15 years (not yet 16 years) who had been vaccinated five years previously in Study 603-02. In addition, the kinetics of the antibody response will be evaluated in a subset of participants who will receive a booster dose of Menactra® vaccine and children in the same age group not previously vaccinated with a meningococcal vaccine or had meningitis disease who will receive a dose of Menactra® vaccine.

Inclusion criteria

  • Subject is healthy, as determined by medical history.
  • Subject is between the ages of 7 and 15 years (not yet 16 years).
  • For subjects who participated in Study 603-02, subject previously received one dose of Menactra® vaccine or Menomune®-A/C/Y/W-135 vaccine.
  • The date of vaccination during Study 603-02 will have occurred 5 years ± 6 months before the collection of the blood sample obtained for Study MTA23.
  • A negative urine pregnancy test is required for menstruating female subjects.
  • Parent/legal guardian has signed an Institutional Review Board (IRB)-approved informed consent form and subject has signed an IRB-approved assent form.

Exclusion criteria

  • Subjects who participated in sanofi pasteur Study MTA17 Stage I (a subset of subjects from Study 603-02 who had been recruited for the follow-up challenge study)
  • History of documented invasive meningococcal disease
  • Received any other meningococcal vaccine
  • Received any vaccine in the 28-day period prior to enrollment
  • Received antibiotic therapy within the 72 hours prior to collection of a blood sample
  • Actively enrolled or scheduled to be enrolled in another clinical study
  • Serious chronic disease (i.e., cardiac, renal, neurologic, rheumatologic, metabolic, gastrointestinal, psychiatric, or other organ system)
  • Known or suspected impairment of immunologic function
  • Acute medical illness with or without fever within 72 hours or an oral temperature ≥ 100.4°F (≥ 38.0°C) at the time of inclusion
  • Scheduled to receive any vaccination in the 7-day or 14-day period after enrollment
  • Administration of immune globulin, other blood products, or corticosteroid within 8 weeks (56 days) of the study vaccine. Individuals on a tapering dose schedule of oral steroids lasting < 7 days may be included in the trial as long as they have not received more than one course within the last two weeks prior to enrollment.
