Infectious, Pt. 1: Scabs, Pus, And Puritans

The problem with being healthy is that you completely forget what it feels like to be sick. In 2019, many people assume that the history of vaccination is recent history -- maybe a few centuries of innovation starting in the late 1700s. The truth is much more convoluted: centuries of ancient customs developing slowly into a cycle of extremes -- scientific innovation followed by fear, rejection, and sometimes, violence. In the first episode of our special series, 'Infectious,' we explore this recurring cycle and how it echoes still in 2019.
