Polio is no joke: As recently as the 1950s, polio paralyzed or killed over half a million people every year. Thanks to vaccination and herd immunity, polio cases have been reduced to hundreds a year, and public health workers are pushing to send this once widespread disease into the history books, right along with smallpox. And that's worth celebrating, which you can do with our "I enjoy not having polio" pin. Plus, you're supporting clear, science-based information because 50% of profits from this pin are donated to: Voices for Vaccines. This pin is 1.1" tall and has two pinbacks to hold it in place. Designed and made by Dissent Pins.
