En el caso de los corticoides, esto implica ≥ 0,5 mg / kg / día de dosis de prednisona o equivalente. Estarán permitidos los esteroides inhalados o tópicos. • • Durante el período de estudio, participación simultánea en otro ensayo en el que el sujeto ha recibido o se espera que reciba un producto en investigación o no experimental (producto farmacéutico o dispositivo médico). • Teniendo en cuenta la historia clínica y el examen físico, cualquier estado conocido o sospechado de inmunosupresión o inmunodeficiencia. • Antecedentes familiares de inmunodeficiencia congénita o hereditaria. • El historial de reacción o hipersensibilidad probablemente se exacerbe por alguno de los componentes de la vacuna. • Principales defectos congénitos o enfermedades crónicas graves, incluido el síndrome de Kawasaki. • Antecedentes de daño neurológico grave o convulsiones, que incluyen trastornos y episodios de hipotensión o hipo-respuesta, encefalopatías o cualquier tipo de convulsiones (febril y afebril). • Episodio de apnea (cese de la respiración> 20 s) dentro de los 7 días anteriores a la vacunación. • Enfermedad aguda y / o fiebre en el reclutamiento en el estudio. • La fiebre se define como una temperatura ≥ 37.5ºC (temperatura oral o axial) o ≥ 38.0º C (temperatura rectal). • Los sujetos con enfermedades leves (como diarrea leve o infección leve del tracto respiratorio superior) sin fiebre podrían ser reclutados a criterio del médico. • Historial de cualquier terapia de inmunoglobulina y / o producto sanguíneo desde el nacimiento o la administración programada durante el ensayo. • Historial de vacunación o enfermedad contra la difteria, el tétanos, la tos ferina, la hepatitis B, la poliomielitis y el Hib. • Cualquier enfermedad que, en opinión del investigador, interfiera con la evaluación de los objetivos del estudio.• |
