You are painting people in big strokes. The people I know that fear long term effects wear mask religiously and follow safety procedures.
These are also the same people that won't get a flu vaccine, and resist getting the vaccines for all but the most deadly of diseases.
Another comment in this submission mentioned being bad at evaluating risk, perhaps that's what it is. They fixate on the unknowns of a vaccine, but they aren't able to compare it effectively to the risks of the virus.
