- 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)
- 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.

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.

- 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.
