Encephalitis in dogs associated with a batch of canine distemper (Rockborn) vaccine

Abstract

During a period of seven months in 1982-83 cases of postvaccinal encephalitis were recorded in dogs in various parts of Britain after the administration of a particular batch of combined distemper/hepatitis vaccine. Detailed investigations of one of these cases revealed that the distemper component was responsible and the vaccine virus was recovered from the brain of an affected dog.
