That being said, some researchers still have some questions about vaccines and autism; not about mercury, that’s been disproven quite conclusively. But there are some questions about cross-reactivity between some vaccine proteins and neural tissue that can set up an autoimmune reaction in the brain; especially with the measles vaccine. That being said, the epidemilogical picture is one of a complex disorder with a number of contributing factors. Unfortunately, it’s hard to discuss these sorts of ideas in the highly polarized climate that is the vaccine/autism debate.

And frankly, give me a vaccine over small pox any day. And measles, too, for that matter.
