The thing is, it isn't necessarily that vaccines cause "autism" - vaccines with mercury-based adjuvants and preservatives are thought to cause mercury poisoning, and mercury poisoning's symptoms are very similar to "autism". Autism is a real disorder, it is a malfunction of the brain, but many things can cause a brain to malfunction, including poisonous materials. Think of it this way - An allergic reaction to pollen creates cold virus-like symptoms, but that doesn't mean an allergic reaction is a "cold". It is a completely different thing, but the symptoms are alike. It is the same with mercury poisoning and autism. The poisoning causes problems in the brain (this is well-documented), problems that mimic the symptoms of autism. So ppl who say "vaccines cause autism" are not really representing the problem accurately. But the problem definitely exists.
