目的为客观评价云南省陆良县麻疹疫苗常规免疫接种情况和掌握人群免疫水平。方法采取分层和整群抽样(PPS)方法抽取调查单位和调查点。全县共确定3个调查单位(中枢镇、召夸镇、马街镇),9个村级接种点为调查点。结果共监测390人,麻疹接种率为94.10%,麻疹血清抗体阳性率为99.23%。中枢镇麻疹疫苗接种率为96.83%,召夸镇麻疹疫苗接种率为93.85%,马街镇麻疹疫苗接种率为91.79%。各年龄组麻疹疫苗接种率分别为<1岁组71.74%、1~2岁组100%、3~4岁组100%、5~6岁组100%、7~10岁组98%、11~14岁组100%、15~19岁组89.58%、≥20岁组91.49%。各年龄组麻疹血清抗体阳性率分别为<1岁组95.65%、1~2岁组100%、3~4岁组100%、5~6岁组100%、7~10岁组98%、11~14岁组100%、15~19岁组100%、≥20岁组100%。结论召夸镇和马街镇应进一步提高麻疹疫苗接种率,使麻疹疫苗接种率达到国家免疫规划要求的以镇为单位>95%以上。各年龄组麻疹血清抗体均在95%以上,说明人群已建立了良好的免疫屏障,为控制乃至消除麻疹奠定了基础。
Objective To objectively evaluate the routine immunization status of measles vaccine in Luliang County of Yunnan Province and to understand the level of population immunity. Methods The stratified and cluster sampling (PPS) methods were used to extract survey units and investigation points. The county identified a total of three investigation units (central town, called boast town, town Ma), nine village-level inoculation points for the investigation point. Results A total of 390 people were monitored. The measles vaccination rate was 94.10%. The measles serum antibody positive rate was 99.23%. The central town of measles vaccine coverage rate was 96.83%, called the town of measles vaccine coverage rate was 93.85%, Ma Jie town measles vaccine coverage rate was 91.79%. The measles vaccination rates in all age groups were 71.74% of patients <1 year old, 100% of 1-2 years old, 100% of 3-4 years old, 100% of 5-6 years old, 98% of 7-10 years old, 100% in the 14-year-old group, 89.58% in the 15-19-year-old group, and 91.49% in the group of ≥20 years old. The positive rates of measles serum antibody in all age groups were 95.65% of <1 year old group, 100% of 1-2 years old group, 100% of 3-4 years old group, 100% of 5-6 years old group, 98% of 11-10 years old group, 11% 100% in the group of ~ 14 years, 100% in the group of 15 ~ 19 years and 100% in the group of ≥20 years. Conclusions Zhaogua Town and Majie Town should further raise the measles vaccination rate so that the measles vaccination rate will reach> 95% of the town required by the national immunization program. Serum antibodies in all age groups were more than 95%, indicating that the population has established a good immune barrier, and control and even eliminate measles laid the foundation.
