One of the more recent issues seems to be that the spike protein is dangerous and causes damage all by itself, just by attaching itself to other cell receptors.
That's a problem, since the C-19 vaccine has convinced millions of shoulder cells to start manufacturing spike proteins.
There is also the problem that vaccine-generated spike proteins are now being discovered everywhere in the body.
In theory, almost all the spike proteins should be localized in the shoulder area.
