Some parents are reluctant to get their kids immunized, because they believe vaccines may cause autism and other problems. Studies that purported to show this have been shown to be bogus. If you refuse your kids immunized, you are doing them a great disservice. From what I have read, the following are more likely causes of the steady increase in rates of dementia, Alzheimer, autism, and ADHD: Fire retardants in furniture; antibacterial soaps; BPA in food packaging; weird chemicals in edible stuff; pesticides; mercury; hormones in meat; alcohol and tobacco used during pregnancy. There may be more as well.
