WASHINGTON – The vaccine additive thimerosal is not to blame for autism, a special federal court ruled Friday in a long-running battle by parents convinced there is a connection.

While expressing sympathy for the parents involved in the emotionally charged cases, the court concluded they had failed to show a connection between the mercury-containing preservative and autism.

“Such families must cope every day with tremendous challenges in caring for their autistic children, and all are deserving of sympathy and admiration,” special master George Hastings Jr. wrote.
