This Week in Virology
TWiV 1298: Clinical update with Dr. Daniel Griffin
By Vincent Racaniello on Feb 21, 2026 08:50 am
In his weekly clinical update, Dr. Griffin and Vincent Racaniello discuss reversal of last week’s no review decision on a flu mRNA vaccine by Vinjay Prasad, appointment of Jay Bhattacharya as CDC director, no experience required, and already detectable reduction in hepatitis B virus vaccination rates, then Dr. Griffin then deep dives into recent statistics on RSV, influenza and SARS-CoV-2 infections, the Wasterwater Scan dashboard, Johns Hopkins measles tracker, where to find PEMGARDA, how to access and pay for Paxlovid, the consequences of measles infection on immune amnesia (shout out to Immune 26), long COVID treatment center, where to go for answers to your long COVID questions, long COVID effect on fertility and type 2 diabetes and contacting your federal government representative to stop the assault on science and biomedical research.
