Polio was once the leading cause of paralysis among children worldwide. But today, the deadly disease is very close to being eradicated. Thanks to vaccines, the number of children affected by polio has been reduced by 99.9%. But to completely eliminate the threat, every child in every household must be vaccinated. On Friday’s #WorldPolioDay, unicef is stressing the importance of working together to end the disease. 📸: UNICEF Saiyna Bashir / ALfilastini / Benekire
