breathe contaminated air in the general vicinity of animals, drink water they’ve pissed or shit in, etc.
Don’t go near animals. Boil water before drinking. Simple as.
That is in fact how a vaccine/our immune system works, yes.
Vaccines work using either diluted toxins, or increasingly, proteins / RNA that just look somewhat like the real thing. The immune system works by enough of the population dying off until only those with the necessary mutations are left.
Animals breathe, just like we do, they can expel airborne viruses that can travel for hundreds, perhaps even thousands of miles. ‘Don’t go near animals’ is like saying ‘just don’t get wet’ in a rain storm: the world is full of animals and they utterly suffuse every aspect of our life in ways that might surprise you.
Vaccines work using either diluted toxins
I don’t know what ‘diluted toxins’ has to do with viruses and immunology since toxins are a rather different matter entirely, but vaccines work (the non-mRNA ones anyway) by infecting you with a weakened version of the virus so that your immune system can learn to identify it without it overwhelming you. Once it learns to identify that disease it will know how to produce proteins and such that can attack the full version (same DNA) should you ever come across it.

Let me state in the sincerest possible terms: lolwut?
It’s not about mutation, the immune system can ‘learn’ and ‘evolve’ over the course of a single human’s lifetime (see: the description of how vaccines work above), it’s not something that you either have a good one or you don’t (autoimmune diseases aside) and the people with bad ones don’t live long enough to reproduce or whatever, your immune system - like your brain - learns by exposure. So being exposed to those diseased animals is literally the only means by which to become immune to them. Viruses do mutate pretty quickly though, so you get the occasional plague/pandemic that overwhelms people’s immune systems when they change enough to not be recognizable to our immune system anymore.
