The League of Extraordinary Virologists celebrate the eradication of wild poliovirus type 3, and consider the effectiveness of an influenza vaccine produced in insect cells, and how small RNAs are protecting the Koala germline from retroviral invasion.

Vincent travels to the European Congress of Virology in Rotterdam and with local co-host Marion Koopmans speaks with Martin Beer, Stephan Gunther, and Vera Ros about their careers and their work on Lassa virus, Borna virus, and insect viruses.

Stephanie joins the super professors to discuss the gut virome of children with serious malnutrition, caterpillar genes acquired from parasitic wasps, and the effect of adding chemokines to a simian immunodeficiency virus DNA vaccine.
