And instead I meant all the stuff that is used to elicit a specific response using some incidental behavior. Those were not part of its evolutionary journey. Those it won't be able to handle and would result in un-predictable regression. That is the monkey-wrench throwing.
>And it's far from perfect at all.
A large number of living things on earth live to their entire lifespan. I think in those cases the immune system did a perfect job.
Things that make you healthier are legitimate input, not things that are "natural". Living naturally doesn't usually mean living healthier.
From another perspective, humanity has already transformed the Earth and ourselves. Ancient mosquito-borne infectious diseases and modern ones are fundamentally different systems. The pace of "natural" species evolution lags far behind the speed at which diseases mutate under modern population densities, nor is it designed for the life expectancy and quality of modern people. Vaccines are one of humanity's best answers to this problem. I see no reason to resist them.

Instead of addressing what I said, you made my response to be about something you can respond to. Which is often a good indication that the person have no idea how to respond to the point raised..
