Some Nigerian kids are pictured showing off the ink marks on their pinky fingers that mean they have been vaccinated against polio. Nigeria celebrates reaching two years without a new case of the wild polio virus today, 24 July 2016. The last Nigerian case of this crippling disease was on 24 July
2014; the country is well on its way to being declared polio-free in 2017 if it does not have another case in the next 365 days.
