Autistic syndrome (Kanner) and vaccination against smallpox (author's transl)
[Article in German]
Eggers C. Klin Padiatr. 1976 Mar;188(2):172-80.
3-4 weeks following an otherwise uncomplicated first vaccination against smallpox a boy, then aged 15 months and last seen at the age of 5 1/2 years, gradually developed a complete Kanner syndrome. The question whether vaccination and early infantile autism might be connected is being discussed. A causal relationship is considered extremely unlikely. But vaccination is recognized as having a starter function for the onset of autism.
