A story widely available today -- a special federal court ruled today what is obvious to most people who can read a scientific article, that there was no connection between thimerosal in vaccines and autism. The court ruling, while sympathetic to parents of kids with autism, was clear and to the point. Science is not on their side, the court ruled. Not even close.
And yet, in terms of what people know, there will remain a certain percentage of people who believe a connection exists. If thimerosal caused autism (and there's no evidence it does), then after it was removed from vaccines the number of autism cases should then decline. They did not.
