There's a low-tech solution at hand. Think about it.

I have to say I am mystified. I have heard about this animal small pox that is contagious but not deadly to humans, and that once healed from it the person is immunized from Small Pox. I have also heard about kooks talking about weird potions.

Very good, Physicist. Is Cow Pox still prevalent enough to provide a sufficient amount of immunization serum ?
