A Study of Meningococcal Vaccine, Menactra® in Healthy Subjects in India

Safety and Immunogenicity Study for Use of Meningococcal (Groups A, C, Y and W-135) Polysaccharide Diphtheria Toxoid Conjugate Vaccine (Menactra®) in Healthy Subjects 2-55 Years of Age in India

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®.

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.

Inclusion Criteria :

• Aged 2 to 11 years or Aged 12 to 17 years or Aged 18 to 55 years of age on the day of inclusion
• For participants aged 2 to 11 years: Provision of informed consent form signed by the parent(s) or legal representative.
• For participants aged 12 to 17 years: Provision of assent form signed by the participant and informed consent form signed by the parent(s) or legal representative.
• For participants aged 18 to 55 years: Provision of informed consent form signed by the participant. If the participant or the participant's parents or legally accepted representative (participants aged 2 to 17 years) are illiterate, an independent witness is required to sign the consent form.

• 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
