KANO, NIGERIA - APRIL 12: A Nigerian schoolboy is vaccinated against polio during a mass nationwide polio inoculation April 12, 2005, in Kano, Nigeria. International aid workers once hoped to have polio eradicated off the face of the Earth by April 2005, the 50th anniversary of the approval of the polio vaccine. But recent efforts by some Nigerian Muslim leaders to stop Western inoculation programs have allowed polio to endure. Creating new victims even while hundreds of thousands of Nigerians suffer from the disease. Opportunities are scarce for polio sufferers, but programs like the Polio Victims Association allow them to make a small living, welding hand-cranked polio bicycles and other projects for a small salary. Nigeria is undergoing a massive countrywide push to inoculate every child under five - nearly 40 million doses of polio vaccine countrywide in four days. (Photo by Chris Hondros/Getty Images)
