Autism Guru Fights for His Reputation and Theory
Susan Dominus, nytimes.com
As people streamed into Graceview Baptist Church in Tomball, Tex., early one Saturday morning in January, two armed guards stood prominently just inside the doorway of the sanctuary. Their eyes scanned the room and returned with some frequency to a man sitting near the aisle, whom they had been hired to protect.
The man, Andrew Wakefield, dressed in a blazer and jeans and peering through reading glasses, had a mild professorial air. He tapped at a laptop as the room filled with people who came to hear him speak; he looked both industrious and remote. Broad-shouldered and fair at 54, he still has the presence of the person he once was: a conventional winner, the captain of his medical school’s rugby team, the head boy at the private school he attended in England. Wakefield was a high-profile but controversial figure in gastroenterology research at the Royal Free Hospital in London when, in 1998, he upended his career path — and more significant, the best-laid plans of public-health officials — by announcing at a press conference that he had concerns about the safety of the measles-mumps-rubella vaccine (M.M.R.) and its relationship to the onset of autism.
Although Wakefield did not claim to have proved that the M.M.R. vaccine (typically given to children at 12 to 15 months) caused autism, his concerns, not his caveats, ricocheted around the world. His belief, based on a paper he wrote about 12 children, is that the three vaccines, given together, can alter a child’s immune system, allowing the measles virus in the vaccine to infiltrate the intestines; certain proteins, escaping from the intestines, could then reach and harm neurons in the brain. Few theories have drawn so much attention and, in turn, so much refutation: a 2003 paper in The Archives of Pediatrics and Adolescent Medicine, which reviewed a dozen epidemiological studies, concluded that there was no evidence of an association between autism and M.M.R., and studies in peer-reviewed journals since have come to the same conclusion. In Britain, the General Medical Council revoked Wakefield’s medical license after a lengthy hearing, citing numerous ethical violations that tainted his work, like failing to disclose financing from lawyers who were mounting a case against vaccine manufacturers. The Lancet, which published the original Wakefield paper, retracted it. In a series that ran early this year, The British Medical Journal concluded that the research was not just unethically financed but also “fraudulent” (that timelines were misrepresented, for example, to suggest direct culpability of the vaccine).
Andrew Wakefield has become one of the most reviled doctors of his generation, blamed directly and indirectly, depending on the accuser, for irresponsibly starting a panic with tragic repercussions: vaccination rates so low that childhood diseases once all but eradicated here — whooping cough and measles, among them — have re-emerged, endangering young lives.
And yet here he was in Texas, post-career-apocalypse, calmly discussing his work, and a crowd of around 250 people showed up to listen. As people walked into the lobby of the church in Tomball, they passed by a whiteboard with a message that asked attendees to express their thoughts to Wakefield. Many complied with lavish thanks: “We stand by you!” and “Thank you for the many sacrifices you have made for the cause!” When he finally took the podium, the audience members, mostly parents of autistic children, stood and applauded wildly.
In his presentation, Wakefield sounded impatient but righteous. He used enough scientific terms — “ataxic,” “histopathological review” and “vaccine excipients” — that those parents who did not feel cowed might have been flattered by his assumption of their scientific fluency. He also tried to defend himself against a few of the charges laid out in The British Medical Journal — offering defenses that did not hold up before the journal’s panel of editors but were perhaps enough to assure an audience of his fans that he did, in fact, have defenses. Some part of Wakefield’s cult status is surely because of his personal charisma, and he spoke with great rhetorical flair. He took off his glasses and put them back on like a gifted actor maximizing a prop. “What happens to me doesn’t matter,” he said at one point. “What happens to these children does matter.”
After the talk, a line of visitors snaked down the length of the lobby, his followers waiting to have Wakefield sign a book he wrote about his experience and convictions, “Callous Disregard.” “All right, love?” he said, handing the book back to one mother. “Of course,” he said when asked for a photo. A pregnant woman in the lobby told me she was there trying to educate herself. Another woman, with tears in her eyes, blamed herself for not working harder to obtain a separate measles vaccine for her possibly autistic child.
