通过对一起麻疹暴发的调查,发现甲、乙两村接种率相同,但甲村的患病率明显高于乙村。通过分析两个行政村的接种率和接种技术对发病率的影响,最终得出结论,甲村防疫医生在接种麻疹疫苗后总是习惯性地用蘸有消毒液的棉签擦试挤压接种部位,导致麻诊疫苗接种免疫失败,引起了麻疹暴发流行。 Through a survey of an outbreak of measles, we found that the vaccination rate was the same in both A and B villages, but the prevalence in A village was significantly higher than that in B village. Through the analysis of the vaccination rates in two administrative villages and the impact of inoculation technology on the incidence rate, we finally concluded that, after the measles vaccine, the village doctor always used the cotton swab dipped in disinfectant to scrape and squeeze the vaccinated site, Immunization led to measles vaccination failed, causing a measles outbreak.
