On this episode of TWiV, Novavax COVID-19 vaccine demonstrates 90% overall efficacy, preventing an antigenically disruptive change during growth of influenza virus vaccine in chicken eggs, and MIS-C is driven by loss of the gut mucosal barrier.
For the first TWiV of 2020 we reveal that microbiome depletion with antibiotics alters the immune response to influenza vaccine, and how successive blood meals facilitate virus dissemination in mosquitoes and transmission potential.
A TWiV trio reports on influenza in Australia, how a host protein impacts bird to human movement of influenza virus, and marine DNA viral diversity in the oceans from pole to pole.
Scott Hensley joins the TWiVites to review the current influenza season and presence of the virus in exhaled breath of symptomatic cases.
The TWiVerinoes discuss the potential for prion spread by plants, global circulation patterns of influenza virus, and the roles of Argonautes and a viral protein in RNA silencing in plants.
The TWiVerers answer listener email about genetically modified chickens, a hendra vaccine for horses, online education, curing color blindness, Roosevelt and polio, Th cells, and much more.
Vincent, Dick, Alan, and Delthia Ricks discuss a new influenza virus-like particle vaccine, dog flu, ultrasensitive pen-sized virus detector, imported rabies in the US, Crimean-Congo hemorrhagic fever, and next season’s flu vaccines.
