Not maybe - closer to probably. All the autopsies from earlier COVID deaths show signs of Spike Proteins in the GI as well as many other parts of the body. All one has to do is search for "Spike Protein - (Insert Body organ)" and find out where they (Spike Proteins) have traveled in dead covid patients. Brain, heart ......
So yes - infection is the main job of the spike protein - so maybe our vaccines are working too good. And us dumb long covid patients don't need to know.
