Watch a live video episode of This Week in Virology (TWiV), a podcast about viruses. Started in September 2008 by Vincent Racaniello, a Higgins Professor in the Department of Microbiology and Immunology at Columbia University, the goal of the show is to have an accessible discussion about viruses that anyone can understand and enjoy. In Washington, D.C., Racaniello, co-host Condit, and guests Kawaoka and Hruby discuss antivirals against smallpox and influenza viruses H5N1 and H7N9.
