  摘要 目的 了解全细胞百白破-重组酵母乙型肝炎四联疫苗(DTPw-YHB)中重组酵母乙型肝炎疫苗的免疫原性。方法 进行DTPw-YHB四联疫苗中重组酵母乙型肝炎疫苗与单价的重组酵母乙型肝炎疫苗免疫原性比较,DTPw-YHB四联疫苗中不同含量的重组酵母乙型肝炎疫苗免疫原性比较,以及比较DTPw-YHB四联疫苗放置2~8 ℃保存18个月后,重组酵母乙型肝炎疫苗的免疫效力和稳定性。结果 经检测DTPw-YHB四联疫苗中重组酵母乙型肝炎疫苗对小鼠的免疫效果较单价重组酵母乙型肝炎疫苗免疫原性明显增强,小鼠ED50平均比值1∶2.0~1∶3.1; DTPw-YHB四联疫苗中不同含量的重组酵母乙型肝炎疫苗免疫效力无明显区别; DTPw-YHB四联疫苗经2~8 ℃保存18个月后,重组酵母乙型肝炎疫苗的稳定性良好。结论 DTPw-YHB四联疫苗中重组酵母乙型肝炎疫苗的免疫原性高于单价的重组酵母乙型肝炎疫苗。未见DTPw对重组酵母乙型肝炎疫苗的免疫原性有干扰抑制现象,表明DTPw与重组酵母乙型肝炎疫苗相容性好。

  Abstract Objective To study immunogenecity of yeast-derived recombinant hepatitis B (YHB) component in diphtheria-pertussis-tetanus-YHB vaccine (DPTw-YHB). Methods Immunogenecity of tetra-valent DTPw-YHB vaccine and mono-valent recombinant YHB vaccine, and that of the tetra-valent vaccine with varied YHB component were compared.The efficiency and stability of recombinant YHB in the tetra-valent vaccine stored at 2~8℃ for 18 months were determined. Results The efficiency of recombinant YHB in the tetra-valent vaccine enhanced significantly in mice,as compared with that of mono-valent recombinant YHB vaccine, with an average mouse ED50 of 1∶2.0~1∶3.1.There was no significant difference in efficiency of the tetra-valent vaccine with varied recombinant YHB component.Recombinant YHBin the DPTw-YHB tetra-valent vaccine still kept good stability stored at 2~8℃ for 18 months. Conclusion Recombinant YHB in the tetra-valent vaccine was more immunogenic than the mono-valent YHB vaccine.No interference and inhibition of DPTw to recombinant YHB was found,indicating good compatibility between DPTw and YHB.
