As the COVID-19 pandemic continues, new questions have arisen in regards to the ethics of global vaccine distribution. In a continuation of a series started over the summer, University of Pennsylvania's Ezekiel Emanuel returns to discuss boosters and vaccine hesitancy and how that affects vaccine distribution around the world. Plus, he shares his thoughts on Biden administration policies concerning the travel ban due to the Omicron variant, domestic mandates, testing, and masking. For more on these issues, read "On the Ethics of Vaccine Nationalism: The Case for the Fair Priority for Residents Framework," co-authored by Dr. Emanuel and published by Carnegie Council's Ethics & International journal and Cambridge University Press.  For a full transcript of this talk, please go to carnegiecouncil.org.
