title: Neuroparalytic accidents of antirabies vaccination with suckling mouse brain vaccine. Clinical and pathologic study of 21 cases.
abstract: Twenty-one cases of neuroparalytic accidents of rabies vaccination (with suckling mouse brain vaccine), 11 of them fatal, were observed, occurring predominantly in men; the mean age of the patients was 29 years. On the average, 13 doses of the vaccine were used. Only three patients received less than seven doses. The mean latent period was 14 days (range, 4 to 24 days). In 16 patients (76%), a Guillain-Barré syndrome occurred that was moderate in three, severe in seven, and fatal in six. Pathologically, this was shown to be a typical polyradiculoneuritis. Five patients had fatal involvement of the central nervous system. Three had an acute disseminated perivenous leukoencephalopathy, with concurrent rabies encephalitis in one case. One patient had a perivenous myeloradiculopathy and one a chronic encephalomyelopathy of six years' duration with demyelinating plaques in the periventricular white matter, cerebellum, and spinal cord. Since the reduction of postexposure rabies vaccination to seven doses, no new cases have been observed in Colombia.
