Here is one of many risk calculators, based on UK data: https://qcovid.org/
Unknown factors for the unvaccinated are the severity of new strains (against which the vaccines may not work well though, see the CureVac trials) and long covid (which does exist but is not well studied yet). Unknown factors for the vaccinated are the potential of the spike protein to create havoc in your vascular system (yet a real infection gives you an uncontrollable large dose of it), and the related anecdata about rare severe vascular side effects.
Such unknowns have to be respected when making personal, political and employer decisions. Overconfidence easily slips into failure. People have issues with the related cognitive dissonances and prefer to take and rage defending sides.
