I am reading about a post COVID syndrome that is incredibly reminiscent of POIS, I have not read the causes well also because little is known but without a doubt it is a reinforcement to the thesis of POIS caused by an immune system disorder that for my case I was skeptical in the past even if I am starting to develop a different idea even if it is purely cognitive POIS without physical manifestations, I also wonder if vaccines against COVID what effect they can have on POIS always if there are any, here someone is vaccinated against COVID?
