E.4 | Principal exclusion criteria |
Participants are excluded from the study if any of the following criteria apply: - 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) - 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 - Thrombocytopenia - Bleeding disorder, or receipt of anticoagulants in the 3 weeks preceding inclusion, contraindicating intramuscular vaccination based on the Investigator's judgment - Personal or family history of Guillain-Barré Syndrome (GBS) - Personal history of clinically significant development delay (at the discretion of the Investigator), neurologic disorder, or seizure disorder NOTE: The above information is not intended to contain all considerations relevant to a patient's potential participation in a clinical trial. |
Se excluirá del estudio a los participantes que cumplan alguno de los siguientes criterios: -Inmunodeficiencia congénita o adquirida, conocida o sospechada, o recepción de terapias inmunosupresoras, como quimioterapia o radioterapia anticancerosa, en los últimos 6 meses, o terapia con corticoides sistémicos de largo plazo (prednisona o equivalente durante más de 2 semanas consecutivas en los 3 meses anteriores). - Hipersensibilidad sistémica conocida a cualquiera de los componentes de la vacuna o antecedentes de reacciones que pongan en peligro la vida por administración de las vacunas utilizadas en el ensayo, o a una vacuna que contenga cualquiera de las mismas sustancias. - Trombocitopenia. - Trastornos hemorrágicos o administración de anticoagulantes en las 3 semanas anteriores a la inclusión, por lo cual quede contraindicada una vacunación intramuscular según el criterio del investigador. - Antecedentes personales o familiares de síndrome de Guillain-Barré (GBS). - Antecedentes personales de retraso clínicamente significativo del desarrollo (a juicio del investigador), de trastorno neurológico o de trastorno convulsivo. NOTA: no está previsto que la información anterior contenga todos los aspectos relevantes para la posible participación de un paciente en un estudio clínico. |
