TWiV 1122: Clinical update with Dr. Daniel Griffin

June 15, 2024

In his weekly clinical update, Dr. Griffin discusses expanded use of the RSV vaccine by GSK, how the youngest member of the MicrobeTV family was hospitalized with RSV, why we are seeing more RSV infections than before the pandemic and how administration of monoclonal antibody therapy does not prevent infection but disease, before reviewing the weekly US COVID update, how SARS-CoV-2 affects neurodevelopment of the fetus and probability of preeclampsia, if giving Paxlovid prevents long COVID, and FDA recommends switching from the XBB.1.5 variant to JN.1 for fall COVID-19 vaccine formulations.
