Here we see Nigerian Field Epidemiology Training Program (NFETP) resident, Dr. Wada Imam Bello, making his way bare footed across a stream, as he was in the process of carrying oral polio vaccine (OPV) in an effort to reach the “unreachable” nomads in the Fulani communities inhabiting the Sabon Layi Ward, of the Local Government Area (LGA) of Faskari, in Katsina State, Nigeria, in August, 2012. This endeavor was part of the Centers for Disease Control and Prevention's (CDC) Nomadic Mission.
”Polio is a crippling and potentially fatal infectious disease. There is no cure, but there are safe and effective vaccines. Therefore, the strategy to eradicate polio is based on preventing infection by immunizing every child to stop transmission and ultimately make the world polio free."
"In 1988, the World Health Assembly adopted a resolution for the worldwide eradication of polio. It marked the launch of the Global Polio Eradication Initiative (GPEI), spearheaded by national governments, CDC, Rotary International, WHO, and UNICEF, with substantial support from the Bill & Melinda Gates Foundation.”
