[Vaccine poliomyelitis in an adult undergoing chemotherapy for non-Hodgkin lymphoma].

Paralytic disease was observed in a 68-year-old man with non-Hodgkin lymphoma following administration of oral live poliomyelitis vaccine. The vaccine had been administered during a vaccination campaign just before the patient underwent chemotherapy with cyclophosphamide. The dangers intrinsic in vaccination campaigns, i.e. of failure to individualize risks and benefit of the vaccination, are discussed.
