TWiV 1272: Clinical update with Dr. Daniel Griffin

Nov 22, 2025

Dr. Daniel Griffin, a clinical virologist, dives into critical updates on infectious diseases. He discusses alarming CDC changes regarding vaccines and autism, the detection of wild poliovirus in Germany, and the first human case of H5N5 in the U.S. The Marburg outbreak in Ethiopia raises concerns about its impact, while avian flu devastates elephant seal populations. Griffin also highlights rising measles cases in North America and offers insights into RSV vaccination strategies, long COVID treatments, and the importance of continued vaccinations.

Episode notes

INSIGHT

CDC Page Change Fuels Vaccine Doubt

The CDC removed the headline "Vaccines do not cause autism" citing the Data Quality Act and said the claim isn’t evidence-based.
Daniel Griffin and Vincent Racaniello warn this change fuels vaccine hesitancy and undermines CDC credibility.

INSIGHT

Polio Detected In German Sewage

Wild poliovirus type 1 was detected in German sewage, the first such detection in Europe since 2010.
Vincent notes Germany’s surveillance likely caught an import from endemic regions and high inactivated vaccine coverage limits outbreaks.

INSIGHT

Marburg Outbreak In Ethiopia

Ethiopia reported its first Marburg virus outbreak with multiple deaths and many exposed.
Daniel links Marburg’s reservoir to Egyptian fruit bats and stresses close monitoring of the cluster.

In his weekly clinical update, Dr. Griffin and Vincent Racaniello are dismayed by the changes on CDC vaccine website positively stating the link between autism and vaccination, the finding of wild type poliovirus 1 in Germany, Marburg virus in Ethiopia, decimation of the elephant breeding colony by H5N1 and the first human case of H5N5 influenza virus infection before Dr. Griffin deep dives into recent statistics on the measles epidemic, RSV, influenza and SARS-CoV-2 infections, the Wasterwater Scan dashboard, Johns Hopkins measles tracker, antibody escape by seasonal flu viruses, where to find PEMGARDA, how to access and pay for Paxlovid, long COVID treatment center, where to go for answers to your long COVID questions, if resistance exercise aids in recovery from long COVID and contacting your federal government representative to stop the assault on science and biomedical research.
