Reports from across the USA indicates that natural selection IS starting to sort things out in a statistically significant way. Hospitals are reporting 95%+- of all new C19 hospitalizations and deaths are of unvaccinated people. And that has been correlated with states and counties that are Republican led and/or rural, because they have lower vaccination rates coupled with high levels of vaccine hesitancy.
IOW, the people getting sick and dying are in places where vaccination rates are low, are likely to remain so, and are least able to cope with spikes. With Delta on the rise, it’s very possible such regions could face crippling spikes of dangerous & lethal infections…in the areas responsible for huge portions of the national food supply.
