- Receipt of immune globulins, blood or blood-derived products in the past 3 months
- Known or suspected congenital or acquired immunodeficiency; or receipt of immunosuppressive therapy, such as anti-cancer chemotherapy or radiation therapy, within the preceding 6 months; or long-term systemic corticosteroid therapy (prednisone or equivalent for more than 2 consecutive weeks within the past 3 months)
- History of meningococcal infection, confirmed either clinically, serologically, or microbiologically.
- At high risk for meningococcal infection during the trial (i.e., subjects with persistent complement deficiency, with anatomic or functional asplenia, or subjects travelling to countries with high endemic or epidemic disease)
- Known systemic hypersensitivity to any of the vaccine components, or history of a life-threatening reaction to the vaccines used in the trial or to a vaccine containing any of the same substances, including encephalopathy (e.g., coma, decreased level of consciousness, prolonged seizures) within 7 days of administration of a previous pertussis antigen-containing vaccine
- Personal history of Guillain-Barré syndrome (GBS)
- Personal history of an Arthus-like reaction after vaccination with a tetanus toxoid-containing vaccine within at least 10 years of the proposed study vaccination
- Verbal report of thrombocytopenia, contraindicating intramuscular vaccination
- Bleeding disorder, or receipt of anticoagulants in the 3 weeks preceding inclusion, contraindicating intramuscular vaccination
- Deprived of freedom by an administrative or court order, or in an emergency setting, or hospitalized involuntarily
- Current alcohol abuse or drug addiction
- Chronic illness (e.g., HIV, hepatitis B, hepatitis C) that, in the opinion of the investigator, is at a stage where it might interfere with trial conduct or completion
- Moderate or severe acute illness/infection (according to investigator judgment) on the day of vaccination or febrile illness (temperature ≥ 100.4°F). A prospective subject should not be included in the study until the condition has resolved or the febrile event has subsided
- Receipt of oral or injectable antibiotic therapy within 72 hours prior to the first blood draw
- Identified as an Investigator or employee of the Investigator or study center with direct involvement in the proposed study, or identified as an immediate family member (i.e., parent, spouse, natural or adopted child) of the Investigator or employee with direct involvement in the proposed study |
