vaccines + HG = autism:
Well, I can't comment on the toxicity profile of mercury in a developing child and I'm unaware of anyone else who can either.
"Trace amounts of mercury". Do you know what that means? It means "above the limits of detection" but "below the limits of quantitation". It means the quantity is so small it can't even be calculated.
It takes more faith than I have to believe that a single exposure to a small volume containing parts-per-billion levels of mercury would directly cause autism and that it's as simple as that.
Finally, your "peanut allergy" analogy is inappropriate. It argues that a child is pre-disposed to autism as one is with an allergy. You don't take something and then become allergic to it, you're allergic to it before you're exposed to it (it's an example of dis-regulated immunity or "hypersensitivity"). With reference to autism, this would suggest that thimersol is not the cause but the trigger.
As I said before, to which you made no comment, the experimentation required to conclusively prove thimersol is truly responsible for autism cannot be done and therefore any statement to the affirmative is simply not fact.
