Details and patient eligibility

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.

Enrollment: 234 patients

Sex: All

Ages: 7 to 15 years old

Volunteers: Accepts Healthy Volunteers

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

• 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.
