Measles epidemics are still a public health challenge worldwide, necessitating a rapid response. The Jerusalem District Health Office applied a community-oriented intervention during the 2018-2019 epidemic (2150 notified cases). Program development targeted the socioeconomic and cultural characteristics of high-incidence Jewish ultraorthodox communities. Health care and community collaboration led to coverage rates of measles vaccination increasing from 80% to 95% within three months and a significant decline in incidence. Epidemic preparedness calls for maintaining the infrastructure of countermeasures combined with sustaining immunization coverage.
