目的探讨接种流行性腮腺炎疫苗(简称流腮疫苗)与偶合呼吸道感染事件的关系。方法采用现况调查和描述流行病学方法综合分析。结果学湖小学接种流行性腮腺炎疫苗4d后,有46名学生先后出现上呼吸道感染症状,接种流腮疫苗学生罹患率为32.8%,未接种疫苗人群罹患率为18.7%,两组人群间罹患率无明显差异。结论气候变化频繁和当地上呼吸道感染病例增多以及学生密集是导致疫情暴发的主要原因,而接种流腮疫苗后发生暴发疫情纯属偶合,避免在上呼吸道传染病高发季节组织群体性预防接种,以消除偶合呼吸道感染事件对预防接种的负面影响。
Objective To investigate the relationship between vaccination of mumps vaccine (mumps vaccine) and incident respiratory infection. Methods The current status survey and descriptive epidemiological methods were used to analyze the data. Results After 46 days of primary mumps vaccine vaccination, 46 students had symptoms of upper respiratory tract infection. The attack rate was 32.8% in vaccinated mumps vaccine students and 18.7% in unvaccinated patients. There was a significant difference between the two groups No significant difference in rates. Conclusions The frequent causes of climate change and the increase of local upper respiratory tract infections and the concentration of students are the main causes of outbreaks. However, outbreaks after vaccination of gonococcal vaccine are purely coincidental and avoid mass vaccination during the high season of upper respiratory diseases. Eliminate the negative effects of coupled respiratory infections on vaccination.
