In his weekly clinical update, Dr. Griffin and Vincent Racaniello talk about the resignation of a member of the advisory committee for immunization practices and the irony of his rationale that a judge slandered him, vaccinating dairy cattle against H5N1, illnesses resulting from drinking raw milk and the US norovirus outbreak, which is not cruise related, then Dr. Griffin deep dives into the measles outbreak in South Carolina and Utah, recent statistics RSV, influenza and SARS-CoV-2 infections, the Wasterwater Scan dashboard, Johns Hopkins measles tracker, where to find PEMGARDA, safety data of the RSV vaccine for high risk young adults, recognition of unrecognized COVID-19 deaths (but weren't we not allow to call it a COVID-19 in 2020?), retraction of and how the ANTIBIOTIC azithromycin is NOT an antiviral drug, how to access and pay for Paxlovid, long COVID patients with neurocognitive symptoms and contacting your federal government representative to stop the assault on science and biomedical research.
