But they're not wrong in making that risk analysis in the first place.
I do not belong to a risk group for covid-19. I don't live with anyone in a risk group, I don't hang out with people in a risk group or even meet with them. So I don't mind being at the back of the line for this vaccine, the risk of the disease is negligible to me, while the risk of the vaccine is unknown. I don't mind waiting and seeing what happens after millions of people have gotten the vaccine before I get it myself. That minimizes the risk to me.
But my dad belongs to a risk group, so for him the same risk analysis gets a different result, because his risk of dying is a hundred times greater than my risk of dying. So he will try to get vaccinated as soon as he can, as he should.
