Iirc spike proteins have been found in just about every tissue and organ in the body during autopsies, so the manufactures spike proteins definitely get into the bloodstream. Despite the insistence from Big Pharma that this doesn’t happen.

There’s also probably a whole bunch of other crap in the jabs too; lipid nano particles, grapheme oxide, etc. I just focus on the spike proteins because that’s what the jab was designed to do and it’s easier to find info on it and redpill people.
