This is very true, however, 10s of thousands of Americans including myself have animal parts implanted in their bodies to help live a normal life.
Personally, I have an aortic valve made from a pig valve implanted last June when I had open heart surgery.
In my case, they’re no anti-rejection drugs required to keep the body from rejecting the valve.
Is that the norm? Do most people not need anti-rejection drugs when using pig organs?
