Ben joins the TWiV team to reveal the winner of his contest in which influenza viruses carrying different interferon-stimulated genes vie against one another in mice.

The TWiV team consider how the kinase mTOR modulates the antibody response to provide broad protection against influenza virus, and explore the problems with scientific research.

Vincent, Alan, Rich and Kathy review how human placental trophoblasts confer viral resistance via exosome-mediated delivery of microRNAs, and isolation of the first human influenza virus in 1933.

Vincent, Alan, and Kathy discuss new influenza virus NA inhibitors, detection of EEEV antibody and RNA in snakes, and replication of the coronavirus EMC in human airway epithelial cells.
