Autism, vaccines and fear

In 1998, The Lancet, a leading British medical journal, published a research study that triggered one of the biggest health scares of modern times. It claimed that autism was linked to children’s vaccines. The evidence was sketchy – it was based on only 12 cases – but Andrew Wakefield, its lead author, became an instant media celebrity.

Over the next few years, Dr. Wakefield was depicted as a courageous maverick who dared to defy the medical establishment. People’s trust in public health – already tested by the mad-cow scare – collapsed and vaccination rates plunged. Before The Lancet article, the vaccination rate for MMR – the three-in-one shot for measles, mumps and rubella – had reached 91 per cent. A few years later, the rate had slipped to less than 50 per cent in some parts of London, and was far too low to prevent serious outbreaks. In 2008, measles was again declared endemic in the U.K.

The vaccination hysteria proved contagious. In Canada and the U.S., anti-vaccination groups warned about the dangers of thimerosal, a mercury-based preservative used in vaccines (although never used in the MMR one). Parent groups blamed vaccines and environmental toxins for what they said was an autism epidemic. They launched multimillion-dollar lawsuits (all unsuccessful) against vaccine makers, whose product costs, because of legal bills, went up.

Robert F. Kennedy Jr. accused the U.S. government and top scientists of a vast conspiracy to cover up the link between vaccines and autism, and celebrity autism mom Jenny McCarthy argued the case on Oprah .

It’s hard to blame parents of autistic kids for grasping at causes and cures. The causes are poorly understood, and the chance of cure is exceedingly remote. Life with an autistic child is unrelentingly hard. Untested treatments, and claims of cure, run rampant. The field is prone to “pseudoscience and quackery,” says Michael Fitzgerald, a British autism expert and long-time critic of Dr. Wakefield.

Wakefield Saga continues-Lancet completely retracts 1998 paper

Posted in Skepdude by Skepdude on February 2, 2010

The Wakefield castle is starting to crumble. Today, the Lancet, the journal that originally published the 1998 study that started the unjustified MMR vaccine scare, has completely retracted the paper, which is the journal’s way of saying “pretend it never happened” or conversely “can we start from scratch”?

Following the judgment of the UK General Medical Council’s Fitness to Practise Panel on Jan 28, 2010, it has become clear that several elements of the 1998 paper by Wakefield et al1 are incorrect, contrary to the findings of an earlier investigation.2 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.
