Mayo Clinic Q&A: 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. The 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. (Published 12/16/2020)
