Sustaining immunization activities and preventing vaccine-preventable outbreaks during conflict can be achieved through pre-emptive preparedness measures and concerted programmatic and financial support from governments and partners.

Key Evidence: The results of a 2016 cross-sectional polio serosurvey found that the Jordan Ministry of Health’s proactive campaign to locate and vaccinate high-risk populations has been successful in maintaining high population immunity — even with a recent influx of refugees from Syria. The study included a community sample of 479 children under 5 years living in areas of Jordan identified as high risk due to being hard-to-reach, having high numbers of refugees, and lower vaccine coverage (under 90%). Polio immunity was found to be over 96% for polio types 1, 2, and 3 even for children living in refugee camps.
