The results of the 2001 serological survey show that the immunity status of 2-year old children has improved (89.7% seropositive) after the modification of the vaccination schedule while the immunity status for one-year-olds remains poor (57.6% seropositive). The highest prevalence of seropositivity was seen in the age categories from 12 to 44 years (90-97%). The increasing values of seropositivity and relatively higher titers of antibodies (in particular against type 1,3 of B. pertussis) in older children and adolescents likely reflect an ongoing infection in this population.
2001年血清学调查结果显示，在调整疫苗接种计划后，2岁儿童的免疫状况有所改善（血清阳性率为89.7%），而1岁儿童的免疫状况仍然较差（血清阳性率为57.6%）。血清阳性率最高的年龄段为12至44岁（90%-97%）。年龄较大的儿童和青少年血清阳性率不断上升，且抗体滴度相对较高（尤其是针对百日咳杆菌1型、3型），这可能反映出该人群中存在持续感染。
