Many people today wouldn’t recognize what this is. And that’s an amazing thing because it shows how much progress the world has made against polio. This metal tank kept thousands of people alive during the polio epidemic in the U.S. Because of polio vaccines, we no longer need these iron lungs. Iron lungs were once one of the greatest tools to fight polio. Today, it’s the iron will of the thousands of polio workers and their supporters who are committed to finishing the job. I am confident that our tools and resources will allow us to eliminate polio entirely.
