Harald zur Hausen on human papillomaviruses

I interviewed Harald zur Hausen, MD., recipient of the 2008 Nobel Prize in Physiology or Medicine, in Manchester UK at the 2013 meeting of the Society for General Microbiology. We spoke about his career, his work leading to the discovery that human papillomavirus types 16 and 18 are causative agents of cervical cancer, and his thoughts on other agents of human cancers.
