TWiV 1314: Clinical update with Dr. Daniel Griffin April 17, 2026

In his weekly clinical update, Dr. Griffin and Vincent Racaniello are dismayed but not surprised by poll results suggesting most Americans doubt vaccine safety, that the head of the CDC and NIH delayed release of a report on the safety of the COVID-19m vaccine, how Nature works to spread disease without the help of the lab and the about face of the Trump administration to nominate a pro-vaccine candidate for CDC director, before Dr. Griffin then deep dives into the measles outbreak, recent statistics RSV, influenza and SARS-CoV-2 infections, the Wasterwater Scan dashboard, Johns Hopkins measles tracker, how the influenza vaccine may attenuate stroke and acute cardiac disease following virus infection, PEMGARDA authorized use for certain immunocompromised individuals where to find PEMGARDA, how to access and pay for Paxlovid, how the COVID-19 pandemic was a 'negative' for one's mortality where to go for answers about long COVID-19, potential therapies for the pediatric long COVID population and contacting your federal government representative to stop the assault on science and biomedical research.
