Pardon the nit-pick but it's more accurate to say: Virus' variants that avoid immune responses persist.
That is, effectively, to evolve is reactive, not proactive.
- All viruses evolve to avoid immune responses
- The default assumption until we get new evidence should be that COVID-19 behaves like a Coronavirus, where immunity is relatively long-lasting
