At WHO, we know #VaccinesWork. Last year, millions of Somali 🇸🇴 children received vaccines to protect them against #polio, delivered by thousands of trained frontline #healthworkers who walked from house to house with cool boxes on their shoulders. This year, many of these same health workers have pivoted their skills to fight #COVID19. #WHOImpact #EndPolio ⠀ ⠀ Photos by ©️ WHO Somalia / Ilyas Ahmed
