I know that this not might be relevant but here it goes. When it comes to venom some people are immune to it. I personally know a person that is immune to scorpion venom which is my grandmother she is not and has never been vaccinated. I on the other hand am vaccinated with all previous childhood vaccines, I got stung by a scorpion when I was about 7 and almost died by bleeding out and paralysis. It was a horrible ordeal. My theory in a sense is no matter what has been put in the water or in the air or in your body if you have ever vaccinated with a kind of vaccine, either in childhood or adulthood. YOU are forever altered or screwed.
