Abstract：Objective To analyze the status of examining vaccination certificate among children at admission to kindergartens and primary schools in Yunnan Province from 2016 to 2018, and to provide a scientific basis for improving the rates of vaccination and re-vaccination and strengthening infectious disease prevention and control in schools. Methods We collected the data about vaccination certificate verification, re-vaccination of vaccines and related supervision among children at the age of enrolling nurseries and primary schools in Yunnan Province in 2016-2018. Descriptive epidemiological method was used for statistical analysis. Results The verification rates of vaccination certificate in kindergartens & elementary schools and children enrolled in nurseries and primary schools in Yunnan Province were 99.83% and 99.44%, respectively. The possession rate of vaccinationcertificate was 97.78%, and thesupplemental vaccinationrate was 91.92%. The average rate of full-course vaccination was 71.28%, and the rate of supplemental vaccination required was 28.72%. 2.12 doses per person were missed. The overall supplemental vaccination rate about the 10 vaccines in the immunization program was 60.94%, of which the supplemental vaccination rate about BacillusCalmette-Guerin (BCG) vaccine was the lowest (24.02%). The supplemental vaccination rate about vaccine containing measles, diphtheria and group A showed a downward tendency during the 3-year period, with statistically significant differences (χ2=4,297.718, χ2=39.827, χ2=665.308; P<0.01). The verification, possession andsupplementrates of vaccination certificate during the 3-year period showed an increasing tendency year by year(r=0.052, P=0.00). Among 16 prefectures and cities in the province, the rate of full-course vaccination was found to be the highest in Baoshan City (86.68%), but the lowest in Banna Prefecture (50.66%). The supplemental vaccination rate in children from Honghe Prefecture was the lowest, only 25.42%. The possession rate of vaccination certificate and the supplemental vaccination rate were both higher in kindergartens than in primary schools. The supplemental vaccination rate presented an upward trend in primary schools, but a downward trend in kindergartens, showing statistically significant differences (P<0.01). Conclusions The results of vaccination certificate verification of children at admission to nurseries and primary schools in Yunnan Province revealed that the supplemental vaccination rate was low. Schools and community health centers should supervise and follow up the supplemental vaccination work, especially in transferred andfloating children.
