Also available as an enamel pin. 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" sticker. Plus, you're supporting clear, science-based information because 50% of profits from this sticker are donated to organizations that provide credible vaccine information.
