Do children who become autistic consult more often after MMR vaccination?
DeWilde, Carey et al

79 cases with a coded diagnosis of autism were identified. 1 case was excluded where autism was diagnosed before MMR was given and 7 who did not receive MMR.
For the remaining 71 cases, average time between MMR and diagnosis was 1053 days ( 2.9 years), ranging from 1.8 years to 4.7 years. They used 284 controls.
“When consultations in the six months before and after MMR were compared there was a significant fall in consultations in both groups reflecting increasing age but, again, no difference between cases and controls. In contrast, in the six months prior to diagnosis of
autism the consultation rates were significantly higher in cases than controls.”
In conclusion, there is no change in consultation behaviour in autistic children and matched controls in the six months after MMR.
