Just curious if others here share this mutation? I have a natural immunity from Smallpox. I failed 3 attempts at vaccination as a child in the 50's. I never had that scar from the injection my peers had. Smallpox was a virus that killed millions over centuries notably in Northern Europe. Eventually someone or some people were born with a random gene mutation that prevented that particular virus from the ability to enter their cells and passed this mutation on. This has been an interesting thing to me most of my adult life. I have read of a couple of instances where a Smallpox immunity also provides protection to the HIV virus because it attacks human cells in the same manner as Smallpox. I've no proof or studies to back that statement. Just stories from high risk AIDS people who survived when all around them their friends were dying. They, perhaps coincidentally, shared the Smallpox immunity. It's unfortunate this particular mutation did not protect me from contracting another virus, Rubella or as it was called at the time German Measles, at 8 or 9. Nor other colds and various flu strains. At least not the ones I got lol.
