我区1971年以来,每年分别对6个月至6周岁儿童实施百日咳、白喉、破防风三联混合制剂(下称PDT)免疫接种。目前全区白喉平均发病率由六十年代25.48/10万降至5/10万左右。但白喉疫情尚不稳定,个别县发病率有持续回升。为查明原因,1982年我们调查了泉州市、永春及惠安PDT十年来免疫接种方案,并分别抽查15个大队的接种质量和人群易感率。以期对不同免疫方案及接种质量与流行病学效果的关系加以评价,现报告如下。
Since 1971 in our district, Pertussis, diphtheria and tamoxifen triple combination (hereinafter referred to as PDT) were immunized separately every year for children from 6 months to 6 years old. At present, the average incidence of diphtheria in the whole region has dropped from 25.48 / 100,000 to about 5 / 100,000 in the 1960s. However, the diphtheria epidemic is not stable, and the incidence of individual counties has continued to rise. In order to find out the reason, in 1982 we investigated the immunization programs of Quanzhou, Yongchun and Hui’an PDT over the past 10 years, and randomly selected 15 batches of vaccinations and crowd susceptibility. With a view to evaluating the relationship between different immunization programs and vaccination quality and epidemiological effects, the report is as follows.
