Hello, I have a son who has just been softly diagnosed with autism. I'm wondering if I can ask you a question. Is chelation indicated for a child with autism who has never had an immunisation? I'm wondering how he could get metals in him if not the immunisation. Perhaps in the water. IS lead the suspected culprit? What other therapies have you tried and do you think they could chelate a two and a half year old? I'd be grateful for any input. We're reeling with this information and watching our boy regress. Thank you, Kathryn Clarke
