(CNN) -- The medical journal The Lancet on Tuesday retracted a controversial 1998 paper that linked the measles, mumps and rubella (MMR) vaccine to autism.
The study subsequently had been discredited, and last week, the lead author, Dr. Andrew Wakefield, was found to have acted unethically in conducting the research.
The General Medical Council, which oversees doctors in Britain, said that "there was a biased selection of patients in The Lancet paper" and that his "conduct in this regard was dishonest and irresponsible."
The panel found that Wakefield subjected some children in the study to various invasive medical procedures such as colonoscopies and MRI scans. He also paid children for blood samples for research purposes at his son's birthday party, an act that "showed a callous disregard" for the "distress and pain" of the children, the panel said.
Following the council's findings last week, The Lancet retracted the study and released this statement.
"It has become clear that several elements of the 1998 paper by Wakefield et al. are incorrect, contrary to the findings of an earlier investigation. In particular, 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."
Dr. Richard Horton, editor of The Lancet, said he reviewed the GMC report regarding Wakefield's conduct.
"It's the most appalling catalog and litany of some the most terrible behavior in any research and is therefore very clear that it has to be retracted," he said.
The rest.
