No evidence for a new form of autism linked to MMR

Further evidence confirming the absence of a causal link between vaccine for measles, mumps, and rubella (MMR), and autism was published in a study reported in last week’s BMJ online (1). The investigators identified 278 children with childhood autism and 195 with atypical autism born between 1979 and 1998 from computerised health registers of children with disabilities in the community and from special school and child psychiatry records, using the same methods and classifications.
