TWiV 1374: Clinical Update with Dr. Daniel Griffin

In his weekly clinical update, Daniel Griffin and Vincent Racaniello discuss the identification of a type 1 poliovirus outbreak in Syria, the loss of US measles elimination status, use of the influenza vaccine against melanoma, death in Florida from dengue virus infection and return of the virus to the US, wider use of the Ebola ERVEBO vaccine, before Dr. Griffin deep dives into recent statistics on RSV, influenza, SARS-CoV-2 infections and measles, the FDA-approved package inserts for the RSV biologic products, and the magnitude and durability of the immune response following administration of the COVID-19 vaccine in children.
