        Double Immunity

        Learn how Dr. Stephen O'Brien's discovery that people from some European populations carry a genetic mutation that prevents HIV from entering their white blood cells could one day help scientists treat or prevent HIV infection, in this video segment from Evolution: Evolutionary Arms Race. Dating back 700 years, O'Brien theorizes that this mutation was a selective advantage during the bubonic plague, and could be again today, with the onslaught of HIV.
