Is there a connection between thimerosal in childhood vaccines and autism?
• No – studies have shown that there is no link between thimerosal and autism. • Much of the increase in autism is due to a broader definition and inclusion of behaviours and learning disorders that previously had no specific diagnosis. They now fall under what is known as autistic spectrum disorders. • Thimerosal is a safe and effective preservative that has been used in some vaccines since the 1930s. There has never been any scientific evidence that it is harmful in the extremely small amounts used to preserve vaccines.
