TWiV reviews the genetic characterization of a new strain of type 2 oral polio vaccine and its implications for eradication, and how a polymorphism in humans comprising a single amino acid change in an antibody molecule regulates vaccine elicitation of broadly neutralizing antibodies against influenza virus HA.

TWiV revisits chronic wasting disease of cervids and the ability of the prions to infect meadow voles and raccoons, and the suggestion that stochastic assembly of influenza virus particles may play a role in phenotypic diversity.

TWiV explains how cap-snatching, the priming of viral mRNA synthesis with fragments of host mRNAs, can lead to the synthesis of novel viral proteins.

TWiV revisits Brazil’s rejection of Sputnik vaccine, examines influenza transmission via the air from the nasal epithelium of ferrets, and a history of accidental releases of polioviruses and their relevance for eradication of poliomyelitis.

The TWiVsters explain how the shape of pleomorphic virus particles – spherical or filamentous – determines the probability of virus attachment and fusion, and resistance to selective pressure such as antibodies that block cell entry.

From Georgia State University, Vincent speaks with Chris, Andrew, Priya, and Richard about their careers and their work on Ebolaviruses, rotavirus, and antiviral drug development.

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.

From the meeting of the Centers of Excellence for Influenza Research and Surveillance, Vincent speaks with Alan, Florian and Jennifer about their careers, the purpose of CEIRS, universal influenza vaccines, and cellular responses to infection in pediatric populations.
