为了解四川省健康人群白喉、百日咳、破伤风的免疫状况 ,及时为免疫策略提供依据 ,2 0 0 1年对成都等 6个市897名健康者进行了白喉、百日咳、破伤风抗体水平监测。结果显示 :在监测的 4个年龄组中 ,白喉、破伤风抗毒素保护率均 >80 % ,其中 2～ 4岁、5～ 9岁、10～ 14岁白喉、破伤风抗毒素保护率均 >95 % ;2～ 4岁、5～ 9岁、10～ 14岁百日咳抗体几何平均滴度 (GMT)≥ 1:6 4 2 ,保护率均 >75 % ,≥ 2 5岁的百日咳抗体GMT为 1:80 ,保护率2 8 2 1%。按现行的儿童免疫程序接种百白破联合疫苗和白破联合疫苗已收到良好效果 ,对白喉、破伤风、百日咳已经形成了较好的免疫屏障 。
We had surveyed 897 healthy persons for diphtheria, pertussis and tetanus antibodies in 6 cities (Chengdu, Suining, Dachuan, Yaan, Guangyuan, Yibin) of Sichuan Province in 2001. The results showed that in all the 4 age groups surveyed, diphtheria and tetanus antitoxin protective rates were all >80%, in 2-4, 5-9 and 10-14 year age groups, it was higher than 95%. Pertussis antibody geometric titers(GMT) were≥1:642 and protective rates were >75% in 2-14, 5-9 and 10-14 year age groups respectively, but in ≥25 year age group,GMT and protective rate were 1:80 and 28 21% respectively. According to current child immunization programs of DPT and DT vaccines, a better immune barrier against diphtheria, pertussis and tetanus has been established in our province, however, a further immunization of pertussis is needed for adult group.
