Brandt's Tumbling Log

But the underlying argument has not changed: Vaccines harm America’s children, and doctors like Paul Offit are paid shills of the drug industry.

To be clear, there is no credible evidence to indicate that any of this is true. None. Twelve epidemiological studies have found no data that links the MMR […] vaccine to autism; six studies have found no trace of an association between thimerosal […] and autism, and three other studies have found no indication that thimerosal causes even subtle neurological problems. The so-called epidemic, researchers assert, is the result of improved diagnosis, which has identified as autistic many kids who once might have been labeled mentally retarded or just plain slow. In fact, the growing body of science indicates that the autistic spectrum — which may well turn out to encompass several discrete conditions — may largely be genetic in origin. In April, the journal Nature published two studies that analyzed the genes of almost 10,000 people and identified a common genetic variant present in approximately 65 percent of autistic children.

But that hasn’t stopped as many as one in four Americans from believing vaccines can poison kids, according to a 2008 survey. And outreach by grassroots organizations like Autism One is a big reason why.
