Study linking vaccines with autism a 'fraud,' British Medical Journal says

Since the controversial paper by British surgeon and medical researcher Andrew Wakefield, pictured, was published, British parents abandoned the vaccine in droves, leading to a resurgence of measles. Subsequent studies have found no proof that the vaccine is connected to autism, though some parents are still wary of the shot

Dr. Andrew Wakefield, the-now disgraced British doctor who published studies linking vaccines with autism, committed an "elaborate fraud" by faking data, the British Medical Journal said on Wednesday.

The journal's editors said it was not possible that Dr. Wakefield made a mistake but must have faked the data for his study, which convinced thousands of parents that vaccines are dangerous and which is blamed for continuing outbreaks of measles and mumps.

The journal, commonly nicknamed the BMJ, supported its position with a series of articles by a journalist who used medical records and interviews to show that Dr. Wakefield falsified data.

For instance, the reports found that Dr. Wakefield, who included data from only 12 children in his report, studied at least 13 and that several showed symptoms of autism before having been vaccinated.

Fears that vaccines might cause autism have not only caused parents to skip vaccinating their children, but have forced costly reformulations of many vaccines.

"Who perpetrated this fraud? There is no doubt that it was Wakefield," BMJ editor Dr. Fiona Godlee, deputy editor Jane Smith and associate editor Harvey Marcovitch wrote in a commentary, available online.

In 1998, The Lancet medical journal, a rival to the BMJ, published a study by Dr. Wakefield and colleagues linking the combined measles, mumps and rubella (MMR) vaccine with autism.

The other researchers withdrew their names from the study and The Lancet formally retracted the paper in February.

Dr. Wakefield denied the allegations.

"The study is not a lie. The findings that we have made have been replicated in five countries around the world," Dr. Wakefield told CNN television on Wednesday.

A disciplinary panel of Britain's General Medical Council said last February that Dr. Wakefield had presented his research in an "irresponsible and dishonest" way and had brought the medical profession into disrepute.

Dr. Godlee and colleagues said the work "was based not on bad science but on a deliberate fraud".

"Clear evidence of falsification of data should now close the door on this damaging vaccine scare," they added.

Many experts have tried to show that vaccines might cause autism. Newer suspicions have focused on thimerosal, a mercury-based preservative once used in many vaccines and since removed from childhood vaccines.

But no studies have shown any clear link. The U.S. Institute of Medicine has issued several reports saying not only is there no evidence of a link, but urging researchers to look elsewhere for possible causes of autism, which affects an estimated 1 in 110 children in the United States, according to the Centers for Disease Control and Prevention.

The U.S. Center for Disease Control says nearly 40 per cent of U.S. parents have some mistrust of childhood vaccines.
