This Week in Virology

In his weekly clinical update, Daniel Griffin and Vincent Racaniello continue their ongoing exasperation over 5 deaths in Pennsylvania associated with measles infections, the absurdity of RFK Jr.’s statement that AI is better informed than physicians, the outbreak of cholera, more deaths by raw milk products, spread of dengue virus in Florida, Ebola in DRC, refusal to acknowledge the benefits of the HBV vaccine birth dose, how TORCH agent infections impact neurodevelopment and may lead to increase chances of autism diagnosis, Legionnaires disease and screw worm cases, before Dr. Griffin deep dives into recent statistics on RSV, influenza, SARS-CoV-2 infections, the continued measles outbreak in Pennsylvania, US, and Canada, modeling predictions of the outcome for repealing measles vaccination requirements to enter school in Florida, reactogenicity of different COVID vaccines and contacting your federal government representative to stop the assault on science and biomedical research.
