[Acute disseminated encephalomyelitis after active immunization against early summer encephalitis].

After repeated immunization against european spring-summer encephalitis, a 36-year-old patient developed recurrent retrobulbar neuritis, had a fit of grand mal epilepsy and a focal motor clonic-tonic attack status as a result of post-vaccination ADEM. Post-vaccination encephalomyelitis after TBE-vaccination is a very rare complication of vaccination and has so far only been described occasionally. We observed the clinical course of post-vaccination ADEM after TBE vaccination over 12 years.
