<p dir="ltr">In "Disease Waits for No One," Dr. Osterholm and Chris Dall discuss how a federal judge temporarily blocked Health Secretary RFK Jr's rollback of childhood vaccine recommendations. Has the damage of this administration's assault on US vaccine policy already been done? Or is there a chance it could be undone? They'll also dive into a report calling for sweeping changes to how the government tracks COVID vaccine harms, review a recent meningitis outbreak in the UK, cover the latest on measles and avian flu, and answer a listener's question about the risk of catching COVID in public. Plus, we'll bring you the latest respiratory illness update and another public health history segment honoring Women's History Month. <br><br><a href="https://www.cidrap.umn.edu/covid-19/early-official-covid-death-tolls-may-have-undercounted-19"><strong>Early official COVID death tolls may have undercounted by 19%</strong></a> (CIDRAP)<br><br><a href="https://www.cidrap.umn.edu/childhood-vaccines/viewpoint-uncertain-victories-mustn-t-distract-us-staying-focused-defending"><strong>Viewpoint: Uncertain victories mustn’t distract us from staying focused on defending health</strong></a> (CIDRAP and The Vaccine Integrity Project)<br><br><a href="https://www.cidrap.umn.edu/covid-19/new-covid-variant-immune-escape-potential-confirmed-us-22-other-countries"><strong>New COVID variant with immune escape potential confirmed in US, 22 other countries </strong></a>(CIDRAP) <br><br><a href="https://www.cidrap.umn.edu/avian-influenza-bird-flu/california-records-avian-flu-northern-elephant-seals"><strong>California records avian flu in northern elephant seals </strong></a>(CIDRAP)<br><br><a href="https://www.youtube.com/watch?v=4qjzGG6ya9M"><em>All My Babies </em></a>(Georgia Department of Health)<br> </p> <p>Resources for vaccine and public health advocacy:</p> <p><a href="https://www.voicesforvaccines.org/get-involved/"><strong>Voices for Vaccines</strong></a></p> <p><a href="https://familiesfightingflu.org/take-action/"><strong>Families Fighting Flu</strong></a></p> <p><a href="https://vaccinateyourfamily.org/get-involved/"><strong>Vaccinate Your Family</strong></a></p> <p><a href="https://shotatlife.org/take-action/"><strong>Shot@Life</strong></a></p> <p><a href="https://aspr.hhs.gov/MRC/Pages/index.aspx"><strong>Medical Reserve Corps</strong></a></p> <p>Learn more about the <a href="https://www.cidrap.umn.edu/vaccine-integrity-project"><strong>Vaccine Integrity Project</strong></a></p> <p><a href="https://www.cidrap.umn.edu/covid-19/osterholm-update-covid-19"><strong>MORE EPISODES</strong></a>      </p> <p><a href="https://www.cidrap.umn.edu/support-cidrap"><strong>SUPPORT THIS PODCAST</strong></a></p> <p> </p> <p><strong>Music:</strong></p> <p>"Beauty Flow" Kevin MacLeod (incompetech.com)<br>Licensed under Creative Commons: By Attribution 4.0 License</p>
