What are your thoughts on vaccinations? Do you personally believe they play any role in the development of autism or other chronic diseases? What diseases would you like to see a vaccine manufactured against over your lifetime?
It's not a matter of "personal belief". This isn't a moral dilemma. Asking if I personally believe vaccines cause autism is like asking me if I personally believe gravity is a scientific conspiracy. I'd link anyone with doubts about vaccines to this video https://www.youtube.com/watch?v=3aNhzLUL2ys
