That was a non-hyperbolic illustration of the attitude you'll find among many anti-vaxxers. The ones who won't even wear a mask, since that would be too much of an imposition on their "freedom".

But to address your criticism you've written between the lines, the vaccinated might not die, but they're still at risk for long term complications, were they to contract COVID. And ultimately, the longer this lasts, the more strains will appear, some of which might indeed prove adequate to kill the vaccinated.

A thorough campaign of vaccination, on the other hand, would put an end to this disease, just as vaccination put an end to measles, polio, whooping cough, mumps, etc. etc.
