That’s the title of this commentary in the latest issue of Archives of General Psychiatry. The author, Dr. Eric Fombonne of Montreal Children’s Hospital, provides his two cents regarding a new study in the same issue: Continuing Increases in Autism Reported to California’s Developmental Services System: Mercury in Retrograde. In sum, as Dr. Frombonne concludes:
The study by Schechter and Grether in this issue of the Archives provides additional evidence of the lack of association between thimerosal exposure and the risk of autism in the US population. Using an ecologic design and data from the California Department of Developmental Services, the authors showed that the prevalence rate of autism increased continuously during the study period even after the discontinuation of the use of thimerosal in US vaccines in 2001. Had there been any risk association between thimerosal-containing vaccines and autism, the rate of autism should have decreased in young children between 2004 and 2007. Instead, the rate increase did not attenuate, indicating that thimerosal exposure bears no relationship to the risk of autism.
Whatever the science says, there’s at least three reasons why people continue to believe in a vaccine-autism link. Yet like the Vioxx litigation, science only gets you so far once litigation is introduced to the mix.
