Photos: Booth Day in Ghaziabad
Polio vaccinators came to this slum in Ghaziabad, India on the first day of a week-long polio vaccination campaign. India was certified as polio free by the World Health Organization on March 27 this year, but the country remains vulnerable to virus importations. The government along with polio partners—WHO, UNICEF, the U.S. Centers for Disease Control, Rotary International, USAID, and the Gates Foundation—will remain vigilant as long as the polio virus continues to circulate in other countries.
