In 1955, parents rejoiced when the "miracle" polio vaccine arrived. Sixty-seven years later, we still know that #VaccinesWork. Worldwide polio cases have gone down 99.9% since 1988, but recent cases in the U.S. & U.K. remind us that we have to stay vigilant to finally #EndPolio. https://t.co/4TQPurQnky — PolitiTweet.org
