From ASM Microbe in Houston, Texas, Vincent speaks with Eddie Holmes about the evidence that SARS-CoV-2 spilled over into humans in the Huanan Market in Wuhan, absence of evidence for other origins, and his work on the virosphere.
In his weekly clinical update, Dr. Griffin discusses the CDC vaccine advisory group recommending the newly approved RSV vaccines, association of culturable-virus detection and household transmission of SARS-CoV-2, prevention of COVID-19 following a single intramuscular administration of Adintrevimab, real-world effectiveness of Nirmatrelvir/Ritonavir on COVID-19, and COVID-19 convalescent plasma outpatient therapy to prevent outpatient hospitalization.
