A Pakistani schoolgirl, who was displaced with her family from Pakistan's tribal area of Bajur due to fighting between the Taliban and the army, receives a vaccine against polio by a health worker at her makeshift school on the outskirts of Islamabad, Pakistan, Monday, March 10, 2014. "The largest polio virus reservoir of the world," is in Peshawar, in northwestern Pakistan near the border with Afghanistan, according to WHO. Militants have created suspicion among ultraconservative parents in Pakistan's deeply religious northwest, saying the polio vaccine will make their children impotent. The vaccine, they claim, is a ploy by the West to limit the world's Muslim population. (AP Photo/Muhammed Muheisen)
