We’ve known from the git-go that an improperly given shot can cause immediate harm. The needles are built to first allow a slight withdrawal to check for contact with a blood vessel. The BOOK ON THE STUFF says do it. No one seems to do the withdrawal check from what I see. But then injecting the clotashotsnot into a vein takes it straight to an important organ like, oh, say,the heart, maybe lungs, maybe liver. A poorly placed shot WILL DO YOU IN. quickly.
I have had many shots and AFAIK there has never been a vaccine that would kill you if not given in just the right manner.
You are conflating actual information with your own theory.
I’ll just leave it at that.
