O'Brien assembled an international team of scientists to test for the presence of delta 32 around the world. "Native Africans did not have delta 32 at all," O'Brien says, "and when we looked at East Asians and Indians, they were also flat zero." In fact, the high levels of delta 32 found in the study were only matched in regions of Europe that had been affected by the plague and in America, which was, for the most part, settled by European plague survivors and their descendents.
He began testing the blood of high-risk, HIV-negative individuals like Steve Crohn, exposing their blood to three thousand times the amount of HIV normally needed to infect a cell. Steve's blood never became infected. "We thought maybe we had infected the culture with bacteria or whatever," says Paxton. "So we went back to Steve. But it was the same result. We went back again and again. Same result." Paxton began studying Crohn's DNA, and concluded there was some sort of blocking mechanism preventing the virus from binding to his cells. Further research showed that that mechanism was delta 32.The results of the Eyam study suggest that delta 32 may have helped save Europe from the bubonic plague pandemic and will save it again from AIDS.
In order to be immune both parents have to be European plague survivor descendents. Wow, I'm thinking with irish/german mix blood I might be good to go.
