山东省德州市 １９９０～ １９９４年间，对健康人群 １１３７人进行麻疹血凝抑制（ＨＩ）抗体水平的监测。结果表明，麻疹ＨＩ抗体平均阳性率９３．８４％，几何平均滴度（ＧＭＴ）１：２４．４６。通过加强计划免疫管理，麻疹ＨＩ抗体阳性率和ＧＭＴ有增高的趋势。但亟需免疫保护的８～２３月龄儿童麻疹ＨＩ抗体阳性率仪为８２．５０％，ＧＭＴ为１：１５：６３，均极明显地低于其它年龄组人群，应加强麻疹疫苗的基础免疫工作。
During the period from 1990 to 1994 in Dezhou City, Shandong Province, 1137 healthy people were monitored for HI antibody levels. The results showed that the average positive rate of measles HI antibody was 93.84%, and the geometric mean titer (GMT) was 1: 24.46. By strengthening planned immunization management, measles HI antibody positive rate and GMT have an increasing tendency. However, the HI antibody positive rate of measles in children aged 8 ~ 23 months who needed urgent immunization was 82.50% and the GMT was 1:15:63, which were significantly lower than those in other age groups. The basic immunity of measles vaccine should be strengthened jobs.
