In this episode virologist Levi Yant walks us through the science of Covid - 19. We discuss what a virus is, what makes Covid 19 different, why we're in a global pandemic and what we can do about it. If you're feeling confused by all the information out there and you're unsure of what is right and wrong in this mad new world we live in, take a listen. Our behaviour has never been so important.  Levi Yant has a postgraduate degree in Virology in HIV vaccine development. After forming a research group in evolutionary biology at Harvard, he moved to the University of Nottingham and is an Associate Professor in the Faculty of Medicine and Health Sciences.
