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.

TWiV 1110: Clinical update with Dr. Daniel Griffin

In his weekly clinical update, Dr. Griffin begins with discussing if the antibiotic neomycin is really a pan-antiviral countermeasure, then reviews the recent statistics on SARS-CoV-2 infection before deep diving into if shedding and the rapid antigen test results correlate, the guidelines for spring administration of COVID vaccines boosters, whether COVID booster associates with the long COVID prevalence, discusses the emergency use application of a pre-exposure prophylactic, revised guidelines for how to treat respiratory viral infection guidelines by the CDC, the caveats for improper use of antibiotics to treat SARS-CoV-2 (a viral infection), continues to dispel the myth of viral rebound, when to use steroids and the benefits of convalescent plasma, what do when healthcare workers succumb to SARS-CoV-2 infection, if administration of an anti-immunoglobulin E monoclonal antibody can be used for COVID-19 treatment, if inhibiting T-cell activation will reduce secretion and production of inflammatory cytokines including IL-6, if changes in the gut microbiome associate with post -acute COVID-19 syndrome, and the pulmonary and neurologic determinants of long COVID-19 such as the presence of neurofilament light chain in plasma.
