i think it depends on the vaxx that you have been given. with the pfizer and the western ones, you have a higher chance of developing blood clots. i won't give too many details, but i worked in the government back on the country i was born during covid times. when the first three shipments of sputnik came (which took some 3 months in total i think), one of the guys at the center where the shots were given told me that they were basically just water with a placebo effect at that point because during shipping they couldn't manage to get the temperatures right, so it lost the cold chain or whatever it is called in english, so it lost effectiveness and it became sort of "inert". still i didn't get it, but my colleagues did and i noticed that nobody had any reaction at all during the days they took it. after some 4 months, the pfizer and moderna arrived, and some of my colleagues that didn't get the second sputnik due there not being more of those took them, and they became really ill. one of my colleagues actually developed a blood cloth and had to be hospitalized. another had to be on a respirator. it was surreal to watch it in first person after reading about it second hand.
