About this episode:

Thanks to vaccines, most people under a certain age have no memory of the devastation and terror caused by the poliovirus. Although widely eliminated, polio still poses a threat in certain countries around the world. Waning vaccination rates in pockets of the U.S. mean some communities are at risk of a resurgence. In this episode: a look back at polio before vaccines, and how technology has evolved—including a discussion about a previous version of the vaccine that did, in rare instances, actually cause paralytic polio.

Dr. Bill Moss is the executive director of the International Vaccine Access Center at the Johns Hopkins Bloomberg School of Public Health.

Host:
