The basis for the argument that thimerosal-containing vaccines cause ASD is that increased exposure to thimerosal-containing vaccines results in an increase in the prevalence of ASD. The corollary is that ASD should DECREASE as exposure to thimerosal-containing vaccines decreases. This has been tested repeatedly, and the answer clearly shows that thimerosal-containing vaccines are NOT responsible for the increase in the apparent prevalence of ASD. Studies in Canada, California, Finland, Denmark, and Sweden emphatically refute the hypothesis.
The latest report is consistent with the results of previous epidemiological, cohort, and case-control studies; it shows that discontinuation of thimerosal did not affect the prevalence of ASD among children born as much as six years following the dramatic reduction of exposure to thimerosal-containing vaccines.

Joe Blow is several years behind the curve. Even the petitioners in the failed Omnibus Autism Proceedings acknowledged that if thimerosal caused any cases of autism at all, it must be so rare that those cases could not be detected by epidemiological studies. Blow is flogging a dead hypothesis.
