NCT00444951

Brief Summary

This study will be conducted among adolescents in Saudi Arabia who previously received one dose of A, C, Y, W 135 and at least one dose of A, C meningococcal polysaccharide vaccine. This study will evaluate the booster administration of Menactra® (Meningococcal A, C, Y, and W 135 Polysaccharide Diphtheria Toxoid Conjugate vaccine) compared with Mencevax® (Meningococcal A, C, Y, and W 135 Polysaccharide vaccine)in terms of their serum bactericidal antibody responses.

Study Arms (3)

Menactra® group

EXPERIMENTAL

Have received previously a dose of an A, C, Y, W 135 and at least one dose of bivalent A, C meningococcal polysaccharide vaccine, will receive a booster dose of Menactra® (Meningococcal \[serogroups A, C, Y, W-135\] polysaccharide diphtheria toxoid conjugate) vaccine.

Eligibility Criteria

Age16 Years - 19 Years
Sexall
Healthy VolunteersYes
Age GroupsChild (0-17), Adult (18-64)

You may qualify if:

  • Healthy, as determined by medical history and physical examination.
  • For the Menactra® and Mencevax® groups, one dose of quadrivalent (A, C, Y, W 135) and at least one dose of bivalent (A, C) meningococcal polysaccharide vaccine with no meningococcal vaccine received less than 2 years prior to enrollment.
  • For the Control group, no previous history of any meningococcal vaccination.
  • Informed consent form signed by the parent(s) or other legal representative for subject under 18 years and signed by subject him/herself if subject above 18 years old
  • Able to provide a vaccination log or has available vaccination record in the Health Center
  • Able to attend all scheduled visits and to comply with all trial procedures

You may not qualify if:

  • Serious chronic disease (i.e., cardiac, renal, neurologic, metabolic, rheumatologic, psychiatric, etc.)
  • Known or suspected impairment of immunologic function.
  • Administration of immune globulin or other blood products within the last three months, injected or oral corticosteroids or other immunomodulatory therapy within six weeks of the study vaccine. Individuals on a tapering dose schedule of oral steroids lasting \< 7 days may be included in the trial provided that they have not received more than one course within the last two weeks prior to enrollment.
  • Oral or injected antibiotic therapy within the 72 hours prior to vaccination
  • Received any vaccine in the 14-day period prior to study vaccination, or scheduled to receive any vaccination during the 14-day period after study vaccination.
  • Previous history of documented invasive meningococcal disease.
  • Systemic hypersensitivity to any of the vaccines components or history of a life-threatening reaction to the trial vaccines or a vaccine containing the same substances
  • Participation in another clinical trial in the 4 weeks preceding the trial vaccination
  • Planned participation in another clinical trial during the present trial period
  • Any condition, which, in the opinion of the investigator, would pose a health risk to the subject, or interfere with the evaluation of the vaccine.
  • Personal or family history of Guillain Barré syndrome.
