Although an effective polio vaccine is widely available, there are four countries in the developing world in which the virus remains. To wipe polio out completely, every child in every region where the virus still lives must be vaccinated. Watch this video to find out how researchers, governments, and public health professionals are collaborating to find all these children and stop this disease in its tracks.
I hope this goal gets accomplished.
