Andrew Wakefield - MMR Controversy

MMR Controversy

On 28 February 1998, a paper written by Wakefield and twelve other authors about twelve autistic children was published in The Lancet. In it, the authors claimed to have identified a new syndrome which they called autistic enterocolitis, raising the possibility of a link between a novel form of bowel disease, autism, and the MMR vaccine. In the study's "findings", the authors noted that the parents of eight of the twelve children linked what were described as "behavioural symptoms" with MMR, and in its "results" reported that the onset of these symptoms began within two weeks of MMR vaccination. In the published Lancet summary, known as the "interpretation", the authors wrote:

"We identified associated gastrointestinal disease and developmental regression in a group of previously normal children, which was generally associated in time with possible environmental triggers."

These possible triggers were reported to be MMR in eight cases, and measles infection in one. The paper was instantly controversial, leading to widespread publicity in the UK and the convening of a special panel of the UK's Medical Research Council the following month. One study done based in Japan found that there was no causal relationship between the MMR vaccine and autism in groups of children given the triple MMR vaccine and children who received individual measles, mumps and rubella vaccinations. The MMR was replaced with individual vaccinations in 1993.

Although the paper said that no causal connection had been proven, and before it was published, Wakefield made statements at a press conference and in a video news release issued by the hospital, calling for suspension of the triple MMR vaccine until more research could be done. The press conference was later criticized as 'science by press conference'. According to BBC News, it was this press conference, rather than the Lancet paper, that fueled the MMR vaccination scare. According to the BBC, "He told journalists it was a 'moral issue' and he could no longer support the continued use of the three-in-one jab for measles, mumps and rubella. 'Urgent further research is needed to determine whether MMR may give rise to this complication in a small number of people,' Dr Wakefield said at the time." He said, "If you give three viruses together, three live viruses, then you potentially increase the risk of an adverse event occurring, particularly when one of those viruses influences the immune system in the way that measles does." He suggested parents should opt for single jabs against measles, mumps and rubella, separated by gaps of one year.

In December 2001, Wakefield resigned from the Royal Free Hospital, saying, "I have been asked to go because my research results are unpopular." The medical school said that he had left "by mutual agreement." In February 2002, Wakefield stated, "What precipitated this crisis was the removal of the single vaccine, the removal of choice, and that is what has caused the furore – because the doctors, the gurus, are treating the public as though they are some kind of moronic mass who cannot make an informed decision for themselves."
