Paul and Theodora return to TWiV to explain their research on determining the number of neutralizing epitopes on the SARS-CoV-2 spike that are recognized by antibodies, and engineering of a polymutant spike with twenty amino acid changes that demonstrates the high genetic barrier to escape from convalescent serum.
Alessandro Sette joins TWiV to discuss the role of T cells in COVID-19, the finding that amino acid changes in SARS-CoV-2 variants of concern have a negligible impact on T cell reactivity in convalescent patients and vaccinees, and whether a next generation vaccine should include more viral proteins than spike.
TWiV explains the use of a neuronal cell line to study herpes simplex virus latency and reactivation, and a strategy for creating vaccines that induce antibodies against specific epitopes.
Jon and Teddy Yewdell join the TWiV team to talk about their careers, their research, and the problems with biomedical research.
