TWiV reviews viral shedding and antibody responses of men with acute monkeypox virus infection, and gene editing for latent herpes simplex virus infection reduces viral load and shedding.
TWiV reviews influenza H5N1 in North American cows and in birds throughout New York City, polio health emergency extended, ChatGPT to control vaccine hesitancy, increasing viral hepatitis worldwide, dengue public health alert in Puerto Rico, cherry trees drowning in Washington DC, death of iron lung Paul, origin and dispersal history of hepatitis B virus in Eastern Eurasia, and antibody-independent protection against heterologous SARS-CoV-2 challenge.
TWiV reviews a Lassa virus mRNA vaccine that confers protection against disease without inducing neutralizing antibodies, and a CRISPR-based method for engineering the genome of RNA viruses.
Arturo Casadevall returns to TWiV to explain the use of convalescent plasma to treat COVID-19 patients, and the need to support virology at a time when more regulation of experiments is envisioned.
TWiV explains a study of how climate change is predicted to increase cross-species viral transmission risk, and increased memory B cell potency and breadth after a SARS-CoV-2 mRNA vaccine boost.
This episode of TWiV is focused on COVID-19 vaccines and antibodies: who should get boosters, whether a variant matched mRNA vaccine is superior to a historical vaccine, and how the interval between vaccination and infection influences the quality of the antibody response.
Vincent and Brianne review the need to better understand T cell responses to SARS-CoV-2 infection to better inform public health decisions, and how IL-1 and IL-1ra are important regulators of the inflammatory response to RNA vaccines.
Amy returns to TWiV to discuss her work on the identification of cross-reactive antibody responses among diverse enteroviruses, and the implications for our understanding of viral pathogenesis and seroprevalence studies.
TWiV explores the properties of the spike glycoproteins of an influenza B virus discovered in the Wuhan spiny eel, and protection against SARS-CoV-2 infection one year after mRNA-1273 vaccination of nonhuman primates.
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.
