Families from across the U.S. living with autism take part in a rally calling to eliminate toxins from children's vaccines in Washington June 4, 2008. Various U.S. government agencies and non-government health experts agree there is no evidence that can link autism to any kind of vaccine, but a small and highly vocal group of activists remain unconvinced.
