In this episode, which was recorded on Dec. 9, 2020, Dr. Afzal Siddiqui, researcher and Grover E. Murray Distinguished Professor in the Texas Tech University Health Sciences Center School of Medicine, gives us a close look at vaccines—how they are developed, how they work and what we can expect from the new COVID-19 vaccines. Dr. Siddiqui’s passion for vaccines isn’t limited to his work. His son and his daughter, both physicians and frontline workers, are expected to be among the first ones receiving the COVID-19 vaccine.
