Countermeasures

Countermeasures

Throughout history, humanity has faced down disease and disaster. This season, Countermeasures traces the arc of public health crises and bioterrorism events across centuries, from the Black Death to the 2001 Anthrax attacks. We dig into how societies responded in the moment, what those responses reveal in hindsight, and what we still need to learn. Each episode uncovers the science and the human decisions behind our fight against health threats, and asks what it will take to be ready for the next one. Brought to you by Emergent, a leading public health company that delivers protective and life-saving solutions to communities around the world.
