简要总结
To explore the potential benefit of the administration of Menactra vaccine as a two-dose regimen to children.
Primary Objective:
To assess, by age group, the immune response to Menactra vaccine after each vaccine injection.
详细描述
This is an open-label trial designed to explore the immune response to a two-dose schedule of Menactra vaccine compared with a standard one-dose schedule in children.

- •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.
排除标准
- •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.
