A 1998 paper by Wakefield, which was the first study to link a childhood vaccine to autism, was based on doctored information about the children involved, according to a new report on the widely discredited research. The conclusions of the 1998 paper have been renounced by 10 of its 13 authors and was later retracted by the medical journal Lancet, where it was published. (AP Photo/Charles Rex Arbogas, File)
