We basically “cured” most people of cystic fibrosis in the last five years. It is the most miraculous medical breakthrough I can think of, comparable only to insulin treatment for diabetics or the triple cocktail for HIV patients in the 90s. In the span of five years, thousands of cystic fibrosis patients saw their projected lifespans go up to normal. The treatments don’t work on every CF mutation, but they are incredible. The Atlantic published an article last year that made me sob.
