So you'd simply let a pandemic rage for five years?
If they did, some places would likely be completely free of COVID. However, they are not.
They lessen the effects but many people have pointed out that this whole thing is entirely new territory: We have a flu "vaccination" but the flu us just something people learn to live with.
We have never——ever——forced mass vaccination against a viral respiratory infection. Because we cannot vaccinate it away. COVID is here to stay and I (personally) don't think anything will happen until people contract it enough to get a good natural immunity and then things will go away.
