Do you like science and medicine? Do you like history? On today's show, you'll get a great dose of both.

I talk to the author of the very informative book, Between Hope and Fear: A History of Vaccines and Human Immunity, Michael Kinch, PhD.

Dr. Kinch is a professor and Vice Chancellor at Washington University in St. Louis. He has experience developing new medicines for Ebola, Marburg, influenza and other emerging pathogens.
