目的评价麻疹疫苗强化免疫活动后的效果。方法对江苏省连云港市赣榆县2006年麻疹疫苗强化免疫活动和强化免疫前后同期麻疹疫情进行统计学分析。结果赣榆县2006年麻疹疫苗强化免疫接种率96.55%;流行病学效果分析表明,强化免疫前1年麻疹发病专率为4.83/10万,免疫后1年麻疹发病专率为0.55/10万,下降率88.61%,差异有统计学意义(χ2=12.70,P<0.05)。结论控制和消除麻疹疫情,首先确保麻疹疫苗的高接种成功率,其次加强对流动儿童麻疹免疫接种和管理,再次是加大对麻疹疫情监测工作力度,提高实验室诊断率。
Objective To evaluate the effect of measles vaccine after intensive immunization. Methods The epidemic situation of measles vaccine in 2006 in Ganyu County, Lianyungang City of Jiangsu Province was compared with that before and after the intensive immunization. Results The measles vaccine immunization coverage in Ganyu County in 2006 was 96.55%. The epidemiological analysis showed that the incidence rate of measles in the first year before the intensive immunization was 4.83 per 100 000, and the incidence rate of measles in the first year after immunization was 0.55 per 100 000 , The rate of decline was 88.61%, the difference was statistically significant (χ2 = 12.70, P <0.05). Conclusion To control and eliminate the measles epidemic, we must first ensure the success rate of measles vaccination, and secondly, strengthen the measles immunization and management of migrant children. Thirdly, we should intensify the monitoring of measles epidemics and improve the laboratory diagnostic rate.
