Primary Outcome Measures:
  • Percentage of Participants With Meningococcal Antibody Titers ≥ 8 After Each Vaccination [ Time Frame: 30 days post-vaccination ]
    Meningococcal serogroups A, C, Y, and W-135 antibody titers were measured by serum bactericidal assay using human complement (SBA-HC)


Secondary Outcome Measures:
  • Percentage of Participants With Meningococcal Antibody Titers at ≥ 4 After Each Vaccination [ Time Frame: 30 days post-vaccination ]
    Meningococcal serogroups A, C, Y, and W-135 antibody titers were measured by serum bactericidal assay using human complement (SBA-HC)

  • Geometric Mean Titers (GMTs) of Meningococcal Antibodies After Each Menactra® Vaccination. [ Time Frame: 30 days post-vaccination ]
    Meningococcal serogroups A, C, Y, and W-135 antibody titers were measured by serum bactericidal assay using human complement (SBA-HC)

  • Percentage of Participants Reporting Solicited Injection Site and Solicited Systemic Reactions After Dose 1 Vaccination [ Time Frame: 7 days post-vaccination 1 ]
    Solicited injection site reactions: Erythema, Swelling, Pain. Solicited systemic reactions: Fever (temperature), Headache, Malaise, and Myalgia.

  • Percentage of Participants Reporting Solicited Injection Site and Solicited Systemic Reactions After Dose 2 Vaccination [ Time Frame: 7 days post-vaccination 2 ]
    Solicited injection site reactions: Erythema, Swelling, Pain. Solicited systemic reactions: Fever (temperature), Headache, Malaise, and Myalgia.

Criteria

Inclusion Criteria :

  • Aged 2 to < 11 years on the day of inclusion.
  • Provision of assent form signed by the subject (depending on age) and informed consent form signed by the parent(s) or another legally acceptable representative.
  • Subject and parent/legal guardian able to attend all scheduled visits and comply with all trial procedures.

Exclusion Criteria :

  • Previous vaccination against meningococcal disease with either the trial vaccine or another vaccine.
  • Participation in the active (i.e., treatment) portion of another clinical trial investigating a vaccine, drug, medical device, or a medical procedure in the 4 weeks preceding the first 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.
  • Suspected or known systemic hypersensitivity to any of the vaccine components, or history of a life-threatening reaction to a product containing any of the substances present in the study vaccine .
  • Chronic illness at a stage that could interfere with trial conduct or completion, in the opinion of the Investigator.
  • Receipt of blood or blood-derived products in the past 3 months.
  • Received any vaccine (other than desensitization therapy for allergies or influenza vaccine within 2 weeks before vaccination) in the 4 weeks preceding the first trial vaccination.
  • Planned receipt of any vaccine within the 4 weeks following any trial vaccination(s).
  • Known human immunodeficiency virus (HIV), hepatitis B surface antigen (HBs antigen), or hepatitis C seropositivity.
  • History of invasive meningococcal infection (confirmed either clinically, serologically, or microbiologically).
  • Thrombocytopenia, coagulation disorder, or anticoagulant use in the 3 weeks preceding inclusion contraindicating intramuscular (IM) vaccination.
  • Anticipated to receive oral or injected antibiotic therapy within the 72 hours prior to any of the trial blood draws.
  • Personal or family history of Guillain-Barré Syndrome (GBS).
  • 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.
