Study Description

Brief 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®.

Condition or disease	Intervention/treatment	Phase
Meningococcal Infection; Meningitis	Biological: Meningococcal Polysaccharide Diphtheria Toxoid Conjugate (Menactra®)	Phase 3

Detailed Description:

Participants will be enrolled in three age cohorts: Children: 2 - 11 years of age; Adolescents: 12 - 17 years of age, and Adults: 18 - 55 years of age to receive a single dose of Menactra®. They will be followed for a duration of 30 days after vaccination.

Outcome Measures

Primary Outcome Measures :

1. Number of Participants With Vaccine Antibody Titers at ≥ 8 Before and After Menactra Vaccination [ Time Frame: Baseline and 21 days post-vaccination ]
   Antibodies to Menactra vaccine were measured by the Serum bactericidal assay baby rabbit complement (SBA BR) Test.
2. Serum Bactericidal Assay Baby Rabbit Complement (SBA BR) Geometric Mean Titers Before and Post Menactra Vaccination [ Time Frame: Day 0 and Day 30 post-vaccination ]
   Antibodies to Menactra antigens determined by the serum bactericidal assay baby rabbit complement (SBA-BR) test.
3. Percentage of Participants With at Least a 4-fold Increase in Antibodies to Menactra Vaccine Antigens Post Vaccination [ Time Frame: Day 0 to 30 post-vaccination ]
   Antibodies to Menactra antigens determined by the serum bactericidal assay baby rabbit complement (SBA-BR) test.
4. Number of Participants Reporting a Solicited Injection Site or Systemic Reactions Following Menactra Vaccination [ Time Frame: Day 0 to 7 post-vaccination ]
   Solicited injection site: Pain, Erythema (Redness), and Swelling. Solicited Systemic reaction: Fever (Temperature), Headache, Malaise, and Myalgia

• 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
