A federal court is hearing a case in which the plaintiffs believe that mercury in childhood vaccines led to their children's autism, according to a Reuters story.

Their case is the second of three being heard by a special court trying to determine if autism might sometimes be caused by vaccines. Although most medical experts say there is no link, the court can rule there is a plausible association and allow parents of children with autism to get federal compensation from a special vaccine fund.

More than 5,300 cases have been filed by parents who believe vaccines may have caused autism in their children and are seeking payment under the National Vaccine Injury Compensation Program, a no-fault system that pays out for vaccine injuries.
