BACKGROUND: China has been working towards measles elimination, but in 2017, measles outbreaks occurred in Ganzi and Aba prefectures of Sichuan province, representing 95% of all provincial cases and jeopardizing measles elimination.
METHODS: During March and April 2017, high-performing prefectures were paired with outbreak and other interested counties to jointly conduct a measles-rubella (MR) catch-up campaign, build population immunity, and strengthen the counties' programs.
RESULTS: House-to-house search identified 88,383 children in Ganzi that lacked MCV vaccination; 85,144 (96.34%) were vaccinated. Search identified 33,683 children in Aba who were not vaccinated against measles; 33,074 (98.19%) were vaccinated. The supporting prefectures helped install Immunization Information Systems and enroll unvaccinated children into the immunization program.The outbreak ended within a month and incidence has remained low for the subsequent six years.
CONCLUSION: A paired catch-up campaign represents an effective model of using measles elimination strategies to strengthen local immunization programs for long-term program effectiveness.
