Nature News: Smart shots bring Nigeria to brink of polio eradication
“…Nigeria is on the brink of being free of the virus, thanks in large part to its embrace of innovative approaches to vaccination and public health. On 24 July, Nigeria will mark one year since it recorded a case of polio caused by the wild virus … If reached, this landmark will set the stage for polio’s official eradication in Africa — which can only be declared after the region has been free of the virus for three consecutive years — and leave Pakistan and Afghanistan as the only remaining hosts of wild poliovirus…” (Callaway, 7/15).
