The world is gearing up for the next flu pandemic - but this time scientists have vital new clues that could prevent it's spread. In 1918 the so-called Spanish flu killed 20 million people. In this program, QUANTUM follows the discovery of live DNA from the virus, found in the lungs of a woman buried in a mass grave in Alaska in 1918. The discovery was made by a retired pathologist, 73 year-old Dr. Johan Hulton who found the lung tissue specimen after reading of work done by the US Armed Forces Pathology lab. This new information will help in designing a vaccine and in understanding how such pandemics arise.
