The TWiV team reveals a variant SARS-CoV-2 that emerged in deer with deer-to-human transmission, and hybrid virus particles produced by co-infection with influenza virus and respiratory syncytial virus particles.

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.

From ASV 2022 in Madison, Wisconsin, TWiV speaks with Pamela Bjorkman and Andy Mehle about their careers and their research on influenza virus, HIV-1, SARS-CoV-2, and influenza virus.

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 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.

Kizzmekia Corbett joins TWiV to review her career and her work on respiratory syncytial virus, influenza virus, and coronaviruses and coronavirus vaccines, including her role in development and testing of a spike-encoding mRNA vaccine, and then we review the Nobel Prize for discovery of hepatitis C virus.

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.
