In the second episode from the Karolinska Institute in Stockholm, Vincent speaks with Jan Albert, Petter Brodin, and Anna Smed Sörensen about their work on enterovirus D68, systems immunology, and human pulmonary viral infection and inflammation.

The TWiVerinoes discuss the potential for prion spread by plants, global circulation patterns of influenza virus, and the roles of Argonautes and a viral protein in RNA silencing in plants.

Vincent returns to the University of Glasgow MRC-Center for Virus Research and speaks with Emma, Gillian, and Adam about their ebolavirus experiences: caring for an infected patient, working in an Ebola treatment center in Sierra Leone, and making epidemiological predictions about the outbreak in west Africa.
