TWiV reviews freezes and unfreezes of US government grants, how prior COVID-19 vaccination prevents over-reaction of the innate immune response during infections, and how bat genomes illuminate adaptations to viral tolerance and disease resistance. Hosts: Vincent…

TWiV reviews avian H5N1 influenza virus in the US, measles at highest levels in England, positive selection underlies repeated knockout of ORF8 in SARS-CoV-2 evolution, and cross-species spill-over potential of the H9N2 bat influenza A virus.

TWiV discusses a new henipavirus from fruit bats in Madagascar, and attenuation of SARS-CoV-2 Omicron disease in mice caused by genome mutations outside of the spike protein coding region.

TWiV reveals an ACE2-dependent sarbecovirus from Russian bats that is not inhibited by anti-SARS-CoV-2 antibodies, and a modified vaccinia virus Ankara vectored vaccine that protects nonhuman primates from Delta infection.

A TWiV trio reveal the isolation of novel paramyxoviruses from rodents and bats in Arizona, and isolation of naive B cells from seronegative donors that produce germline encoded antibodies which engage the receptor binding domain of SARS-CoV-2, variants of concern, and related sarbecoviruses from bats.

TWiV reveals isolation from bats in Laos of a SARS-CoV-2 like virus with a spike protein that allows entry into human cells, and exploration of a herpesvirus vector for immunization of vampire bats against rabies virus.

Peter Daszak joins TWiV to explain the work of EcoHealth Alliance in surveillance of bats in China for SARS-related coronaviruses to provide the information needed to prevent future pandemics, and why NIH recently withdrew financial support for their work.
