just the mrna vaccines, as they are the ones that create the spike proteins. so as far as i know, moderna and pfizer have these specific problems
and the mrna vax’s are the vast majority of the vaxxes administered
but the others may have their own
the j and j vax has a guillian barr syndrome risk, ie some form of muscular paralysis that may or may not go away over time

J&J vaccine instruct the cells in our arm (where the injection is given) to produce spike protein that is tethered to the surface of the cell. It is not secreted and thus does not float through the body.
According to the NIAID statement, “the spike protein is only detectable for a few days after immunization” in tests conducted in animals.
NIAID ( if you can believe them ) also said that IF enough excess spike proteins are shed into the bloodstream and bind to human cells expressing the ACE2 receptor, an infected person could theoretically experience additional symptoms. However (so they say), this is theoretical; the exact mechanism by which COVID-19 infection leads to cardiovascular symptoms is still unclear <-— an herein lies the unknown.
