" Polio was effectively eliminated throughout the world. And then people just … kind of forgot all about polio. This seems to be the human response to any disease. People forget diseases ever existed the minute they are no longer being affected by them. Maybe that’s understandable. Maybe if we all thought about all the potential diseases the world is teeming with, and the extent to which we are, every day, dancing on the edge of a volcano, the world would seem too terrifying to walk around in at all. Or we’d just vaccinate our kids. "
