You do realise that the Polio vaccine is responsible for wiping out the disease on earth?

Mutant Strains Of Polio Vaccine Now Cause More Paralysis Than Wild Polio

I realize that the Polio vaccine is causing many people in third world countries to develop "Polio-like" symptoms. If they want to try and pretend that Polio has been vanquished by using carefully crafted words such as "Polio-like", well that's certainly their prerogative.

Yes to a), b), and c). No to d)

I can't, not-know the cause of something, based on a statement that you hold to be true. Absence of evidence is not evidence of absence. Or rather, just because I am not aware of evidence that a vaccine causes autism, doesn't necessarily mean that said evidence doesn't exist.

The very fact that you are aware of the phenomenon of vaccine injury, and "autism-like" symptoms really makes me wonder how forthright your being with yourself about the issue. It's clear to me that they are using "autism-like" so that they can maintain the claim that vaccines don't cause autism.

Ask yourself this, when they use the term vaccine. How can we even be certain that they are talking about the entire shot. They may only be addressing the inactive virus, and if that's the case it's simply another shenanigan employed in order to limit their liability.
