I doubt it, because quite a lot, perhaps 20%, of the vaccinated people I have spoken to say they suffered some form of adverse reaction within hours or days.
firstly yellow card reporting, is literally that, its a report of people having some signs of illness with a short period after the vaccine
there is association and causation
association
this just means one event after another -coincidence
causation
one event caused another
over 7 billion doses of covi vaccine have been taken worldwide and scientists in every country are monitoring it very carefully -remember the European Medical Agency paused rollout early on?
in regards to actual reaction to the covid vaccine, Id say there are 2 types:
reaction to the vaccine as a result of the bodies immune response -flu like symptoms typically
and adverse reactions -like blood clots
just remember -adverse reactions are far far rarer than the chance of getting covid and being ill
