Whilst idly browsing -- well, I was reading about Janeane Garofalo, if you must know -- I chanced upon this Salon article about the use of thimerosal in American vaccinations given to babies and small children up until a couple of years ago (and still sent overseas to developing nations).
It makes for pretty shocking reading. Read how the CDC and FDA conspired to suppress research that demonstrated a link between thimerosal and autism in those injected with it.
I bet they injected me with that shit a couple of years ago, when I was forced to subject myself to certain immunisations as part of the green card process. Never mind the fact that I'd already had the diseases as a child, which gave me immunity against them; I couldn't prove I'd had them.
