为了解宁波市人群麻疹免疫屏障形成情况 ,对麻疹的发病情况、麻疹疫苗 (MV)的报告接种率和免疫成功率、人群的免疫水平进行综合分析 ,结果显示 :宁波市麻疹的发病率呈逐年下降趋势 ,至 2 0世纪 90年代以来一直维持在 <5 /10万 ;1986年以来MV的报告接种率均 >95 % ,连续 6年的儿童MV初免成功率 ,除 2 0 0 1年为 94 34% ,其余均为 10 0 % ;人群麻疹血凝抑制 (HI)抗体总阳性率为 97 17%。从目前麻疹的免疫屏障情况分析 ,宁波市近几年不会发生麻疹大规模流行。
In order to understand the formation of measles immune barrier in Ningbo, the incidence of measles, measles vaccine (MV) reported vaccination and immunization success rates, population immune levels were analyzed, the results showed that: the incidence of measles in Ningbo City was year after year The declining trend was maintained at <5/10 million since the 90s of the 20th century. The reporting rate of MV vaccination since 1986 was> 95%, and the success rate of MV for children for six consecutive years except for 2001 was 94 34%, the rest were 10 0%; the total positive rate of measles HI was 97 17%.
