A vaccine milestone

The Food and Drug Administration and Centers for Disease Control and Prevention have approved the first of several COVID-19 vaccines developed in response to the pandemic. The first vaccine has been distributed to all 50 states, and vaccinations are underway. Development of safe and effective COVID-19 vaccines has been an extraordinary effort of science and engineering.

\"This is a milestone human achievement by any measure,\" says Dr. Gregory Poland, an infectious diseases expert and head of Mayo Clinic\'s Vaccine Research Group.

On the Mayo Clinic Q&A podcast, Dr. Poland discusses the rollout of COVID-19 vaccines in the U.S. and the timeline for vaccinations.
