[目的]了解福建省健康人群乙脑抗体水平,为评价疫苗接种效应、及时调整疫苗接种策略及制定防治措施提供依据。[方法]在2个区县辖区内采集7个年龄组共630名健康人群血清,用ELISA法进行IgG抗体检测。[结果]乙脑疫苗接种率为53.8%,抗体阳检率为86.0%;不同年龄组人群的接种率及抗体阳性率差异有显著性;不同性别人群的抗体水平类似(2=1.15,P>0.05)。[结论]乙脑疫苗的基础免疫接种率应继续巩固提高,对高龄段人群适当进行疫苗补种,以巩固防治成果。
[Objective] To understand the level of Japanese encephalitis antibody in healthy population of Fujian Province and provide the basis for evaluating the vaccination effect, adjusting the vaccination strategy in time and making prevention and control measures. [Method] The sera of 630 healthy people from 7 age groups were collected in 2 districts and counties, and the IgG antibody was detected by ELISA. [Results] The vaccination rate of Japanese encephalitis was 53.8% and the positive rate of antibody was 86.0%. The vaccination rate and antibody positive rate of different age groups were significantly different. The antibody levels of different sex groups were similar (2 = 1.15, P> 0.05). [Conclusion] The basic immunization rate of JE vaccine should continue to be consolidated and improved, and the vaccine should be replanted to the elderly people in order to consolidate the prevention and treatment results.
