Ah, so NOW they're studying the long-term effects of the jab ... after untold millions have been either duped or arm-twisted into getting the jabs already.
...on guinea pigs who have no choice but to participate.
This makes me wonder if what they really want to study is, what will people do if we force the shot on them (and their children)? Will government agents get shot trying to poison children? Will Brazilians rise up en masse? Will the machetes come out? Or will 99.99% of these 140k Brazilians simply comply, however reluctantly?
