摘要
为了解吸附精制白喉破伤风M联类毒素(DT)减量(0.2ml)加强免疫后的效果,1997年1月和3月,在上默特左旗察素齐镇第七小学,用北京生物制品研究所生产的UT,给154名7岁小学生每人注射0.2ml。结果无一人发热或发生接种部位红肿等临床反应,检测其中53份免疫前和后配对的血清,免疫前白喉抗毒素阳性率为86.79%,免疫后达100%;免疫后有%.23%的儿童抗体滴度有4倍以上增长.同样,检测50份免疫前后配对的血清,免疫前破伤风抗毒素阳性率为88.00%,免疫后达100%;免疫后有96.00%的儿童抗体滴度有4倍以上增长.这说明减量加强免疫是安全的,近期免疫效果是满意的,但其免疫持久性需进一步观察。
Immunization effect was observed in 154 primary school children of 7 years oldwho were revaccinated With an amount-reduced (0.2ml) adsorbent diphtheria-tetanus vaccine(DT) in January and March of 1997.No side effects including fever and swollen in the injectedsite were found and the positive rates for anti-diphtheria toxin in 53 pre-ilnmedzation andpost-immunization paired sera were 86.79% and 100% respeCtively, with a 4-fold, or more,titer increase in 96.23% of the children. Similarly the positive rates for anti-tetanus toxin in50 paired sera were 88% and 100% respectively, the positive rate with a 4-fold titer increasewas found in 96% of the children. The results showed that the injection of 0.2ml amountredueed adsorbent DT is safe and the short period immunization effect is satisfactory, butfllrther, a follow--up observation will be requested to assess the long-term effectiveness.
