If you could be free from autism, would you want to be?
Not relevant to the question at hand. Even if we are to assume that vaccines are autism are linked--and that's a BIG assumption--the question at hand isn't autism vs. not-autism. It's the potential for autism vs. the potential for horrible death or disfigurement.
I can get by in the world with my autism. I can't get by in this world with premature death.
And all that's assuming that the link between vaccines and autism isn't a blatant lie.
