A sub-national polio immunization campaign for hard-to-reach areas was successfully conducted in August. The total number of vaccinated Syrian children inside and outside the camps was 68,274. This includes 17,060 children in Zaatari, and 1,816 children in Azraq. In Zaatari, a rapid convenient assessment for the campaign estimated 98.1% coverage. A post-vaccination campaign coverage survey of 2,100 children was conducted by Royal Medical Services for out-of-camp population, including areas in Irbid, Ajloun and Jarash.
