This Week in Virology – Détails, épisodes et analyse

In his weekly clinical update, Dr. Griffin and Vincent Racaniello record from the ASTMH meeting in Toronto and discuss continuing avian flu outbreaks, the continued global measles outbreak, the effectiveness of high and low doses of the influenza vaccine before Dr. Griffin deep dives into recent statistics on the measles epidemic, RSV, influenza and SARS-CoV-2 infections, the Wasterwater Scan dashboard, Johns Hopkins measles tracker, children hospitalizations following COVID-19 and influenza vaccination, where to find PEMGARDA, how to access and pay for Paxlovid, long COVID treatment center, where to go for answers to your long COVID questions, and contacting your federal government representative to stop the assault on science and biomedical research.
