Paul Offit returns to TWiV to unpack the recent FDA Advisory Panel on COVID vaccines, with discussions on giving everyone the same bivalent vaccine, simplifying the immunization schedule, and how to know when the vaccine should be updated.
TWiV gives an update on poliovirus in wastewater, and reveals a vast world of viroids that infect a wide range of host species in diverse ecosystems.
In his weekly clinical update Dr. Griffin discusses co-detections of other respiratory viruses among children hospitalized with COVID-19, preprint review should form part of PhD programs and postdoc training, early and increased Influenza activity among children, COVID-19 vaccines versus pediatric hospitalization, SARS-CoV-2 variant-related abnormalities detected by prenatal MRI, protective effectiveness of previous SARS-CoV-2 infection and hybrid immunity against the Omicron variant and severe disease, protective effectiveness of previous SARS-CoV-2 infection and hybrid immunity against the omicron variant and severe disease, persistent COVID-19 Symptoms at 6 months after onset and the role of vaccination before or after SARS-COV-2 infection, effect of Dexamethasone use on viral clearance among patients with COVID-19, and the impact of vaccination on post-acute sequelae of SARS CoV-2 infection in patients with rheumatic diseases.

Daniela joins TWiV to discuss her career and her research on T cells, their role in infection with SARS-CoV-2, T cell epitopes and why a variant that evades T cell immunity is not likely to emerge.
In his weekly clinical update Dr. Griffin discusses poliovirus returns to New York wastewater, COVID-19 is more widespread in animals than we thought, increasing ventilation reduces SARS-CoV-2 airborne transmission in schools, the use of carbon dioxide monitoring to assess ventilation at a national infectious diseases conference, effectiveness of the bivalent mRNA vaccine in preventing severe COVID-19 outcomes, 7-month duration of SARS-CoV-2 mucosal immunoglobulin-A responses and protection, and long COVID outcomes at one year after mild SARS-CoV-2 infection.
Felicia joins TWiV to discuss her career and her research on human cytomegalovirus, which infects most of us for our entire lives yet mainly causes disease in the immunosuppressed.
