To answer your original question, no I would not hunt with an outfitter or patronize any other business for that matter who would require proof of vaccination. Although I recognize the right of a private business to require this, it is also my right to choose who I do business with based on my personal principles.
To force unwanted or unnecessary medicine or medical procedures upon someone is not only a violation of human rights, it defies the fundamental freedoms we were afforded by our US Constitution that at least some of us still hold sacred. This is not just a US concept. The entire free world post-WW2 formulated and agreed to these basic human rights. I suppose western society has forgotten the Nuremberg Code over the last 70+ years?
Regardless of the rationalizations they offer, when you allow a government to manufacture reasons for taking away your freedoms in the name of the "greater good", you have opened the door to tyranny. I personally believe upholding the foundational principles of our freedoms as the true "greater good" in the end..
