No people have gone through their life without catching the cold and very few without catching the flu at least once, despite having flu vaccines for a few decades now.

Not all viruses are the same, and sarscov2 is much more like cold/flu than polio.

Specifically, saracov2 has reservoirs in animals. Unless you had an effective vaccine that also works for cats, dogs, deer etc and the ability to actually deploy it (think wild deer all over the US), it’s here to stay.

Create an animal vaccine, give hunters dart guns and free rein to shoot as many as they can. Then see what happens.

You are underestimating the geographical spread and numbers of deer in the us. And likely also overestimating the number and ability of hunters.
