I'm NOT an expert on this, BUT (as I understand it) evolution is the process by which species "evolve" (adapt/change) to survive within their relative ecosystems. Thus, the phrase "all things must grow, or die".............. Failure to adapt (EVOLVE) results in eventual extinction.
Refusing to accept a life preserving vaccination to prevent a possible mutation that evades the vaccinations available is a FAILURE to adapt.
Virus's are a known entity. We have KNOWLEDGE of them. Why wouldn't they be looked at as Nature's WAY of fighting back against a species that seems hellbent on destruction of the Globe. Only those that evolve will be able to survive vs. some virus. Nature's way. Survival of the fittest.
Those INTENT on self delusion and willful ignorance (STUPIDITY) will die out.
Who am I to argue with that?
Fact is, in some cases I tend to agree with the necessity of Nature's ultimate Law!
