From Autism Watch:
The Lancet has retracted publication of a 1998 paper  whose authors—led by Dr. Andrew Wakefield—suggested that the measles-mumps-rubella (MMR) vaccine might be linked to autism. The paper didn't declare that cause-and-effect had been demonstrated, but at the press conference announcing its publication, Wakefield attacked the triple vaccine; and he has continued to do so ever since.
The full retraction came five days after The British General Medical Council (GMC), which registers doctors in the United Kingdom, reported that Wakefield had acted dishonestly, irresponsibly, unethically, and callously in connection with the research project and its subsequent publication . Wakefield's misconduct was brought to light by Brian Deer, one of the world's toughest investigative reporters.
In 2004, ten of the study's authors issued a "retraction" which stated: "We wish to make it clear that in this paper no causal link was established between MMR vaccine and autism as the data were insufficient."  Lancet editor Richard Horton—after Deer provided the incriminating evidence—said he should not have published the study and that Wakefield's links to litigation against the manufacturers of the MMR vaccine were a "fatal conflict of interest."  But full retraction had to wait nearly six more years.
The GMC hearings, which began in July 2007, centered on Wakefield's 1998 report. Many studies have found no connections [5,6], but sensational publicity caused immunization rates in the UK to drop more than 10 percent and have left lingering doubts among parents worldwide.
The GMC began investigating after learning from Deer that Wakefield had failed to declare he had been paid £55,000 to advise lawyers representing parents who believed that the vaccine had harmed their children. The GMC found that Wakefield had:
- Improperly obtained blood for research purposes from normal children attending his son's birthday party, paid them £5 for their discomfort, and later joked during a lecture about having done this.
- Subjected autistic children to colonoscopy, lumbar punctures, and other tests without approval from a research review board.
- Failed to disclose that he had filed a patent for a vaccine to compete with the MMR
- Starting a child on an experimental product called Transfer Factor, which he planned to market.
The GMC panel concluded that the allegations against Wakefield could amount to "serious professional misconduct." During the investigation, Wakefield relocated to Austin, Texas, where he helped found Thoughtful House Center for Children, a "nonprofit" clinic that offers many unsubstantiated treatments for autism. He does not have a medical license but oversees the clinic's research program. The clinic's latest (2008) tax filing lists his salary as $270,000 .One more time, just so nobody misses the point here—Andrew Wakefield lied to you. He lied, and because of his lies, children are dead .
