Pakistan is one of three countries left in the world where polio remains endemic. A ban on vaccinations and attacks on health workers mean that the highly infectious disease continues to spread. Since July 2012, at least 22 polio workers have been killed. Some 260,000 children are still not vaccinated and the virus is spreading once again. There is no cure for polio; it can be prevented by vaccination. We can't afford to lose the fight against polio, so please support the cause.
