[Neurological complications after vaccination against rabies as exemplified by 4 cases from Poznań province].

The author reports 4 cases of neurological complications following vaccination with cerebral-type lyophilized vaccine. The cases were observed in the Province of Poznań in the period from January to April 1984, and the patients were men aged 41 to 60 years with various clinical syndromes: Landry's ascending paralysis, polyradiculoneuritis, polyneuritis and encephalopolyradiculoneuritis. The high frequency of these complications (about 3%) might have been due to the high susceptibility of the vaccinated population, or to technical errors in the production of the vaccine leading to obtaining of a vaccine bath with a high immunoallergogenicity which could trigger off the complication in persons with individual predisposition.
