"India's successful war on polio shows what can happen when its government sets clear policy goals backed with proper funding and real accountability," journalist and author Dan Morrison writes in an opinion piece in the New York Times' "Latitude" blog. He notes that "in the five days spanning Jan. 20 to 25, the Indian government administered polio vaccine to an estimated 172 million children -- a number greater than the entire population of Russia -- in an ongoing effort that has eliminated the disease" in the country. "The complexity of India's polio project is 'unprecedented in the world,' said Anuradha Gupta, a top official at the health ministry who oversees the nationwide effort," Morrison writes, and provides details of the drive carried out last month.
