In an opinion piece in Bloomberg Businessweek's "Small World" blog, Charles Kenny, a fellow at the Center for Global Development and the New America Foundation, examines the effects of "a fake polio vaccination drive organized by the CIA in an effort to collect DNA from [Osama] bin Laden's family" on polio immunization efforts in Pakistan. He writes, "Over the past two months, nearly a dozen polio vaccinators have been killed in Pakistan, most likely by the Taliban," adding, "Heightened popular suspicion and security concerns in Pakistan are putting in danger a remarkable record of global success toward wiping out polio, as well as progress against a range of other infectious diseases that kill millions of kids each year."
