1 00:00:01,533 --> 00:00:03,834 We've made so much progress on polio 2 00:00:03,834 --> 00:00:06,266 because we have a great technical package. 3 00:00:06,266 --> 00:00:09,000 We track where the infections are and we make sure that 4 00:00:09,000 --> 00:00:11,433 vaccination gets to every last child. 5 00:00:11,433 --> 00:00:13,667 That's what will get us over the finish line.
