The Lancet has announced that following the recent GMC Fitness to
Practice Panel judgment it has fully retracted the paper :-

Wakefield AJ, Murch SH, Anthony A, et al. Ileal-lymphoid-nodular
hyperplasia, non-specific colitis, and pervasive developmental
disorder in children. Lancet 1998; 351: 637-641

"...the claims in the original paper that children were "consecutively
referred" and that investigations were "approved" by the local ethics
committee have been proven to be false. Therefore we fully retract
this paper from the published record."
