Summary

The purpose of this study is to assess the safety and immunogenicity of a single dose of Menactra® vaccine to support registration. Primary Objectives: * To describe the antibody titers measured by serum bactericidal activity using baby rabbit complement (SBA-BR) before and after Menactra® vaccination. * To describe the safety profile of participants after one dose of Menactra®.

  • Breast-feeding woman
  • Participation in another clinical trial investigating a vaccine, drug, medical device, or a medical procedure in the 4 weeks preceding the trial vaccination
  • Planned participation in another clinical trial during the present trial period
  • Known or suspected congenital or acquired immunodeficiency, immunosuppressive therapy such as anti-cancer chemotherapy or radiation therapy within the preceding 6 months, or long-term systemic corticosteroids therapy
  • Known systemic hypersensitivity to any of the vaccine components or history of a life-threatening reaction to the trial vaccine or to a vaccine containing any of the same substances
  • Chronic illness, at a stage that could interfere with trial conduct or completion, in the opinion of the investigator
  • Current alcohol abuse or drug addiction that may interfere with the subject's ability to comply with trial procedures
  • Receipt of blood or blood-derived products in the past 3 months, that might interfere with the assessment of immune response
  • Receipt or planned receipt of any vaccine (other than influenza vaccine which can be given 2 weeks or more before vaccination) in the 4 weeks preceding or following the trial vaccination
  • Known Human Immunodeficiency Virus (HIV), Hepatitis B surface (HBs) antigen , or Hepatitis C seropositivity as reported by the participant/parent/guardian and/or based on medical history
  • History of documented invasive meningococcal disease
  • Previous vaccination against meningococcal disease with either the trial vaccine or another vaccine
  • Thrombocytopenia, bleeding disorder or anticoagulants in the 3 weeks preceding inclusion contraindicating intramuscular vaccination
