本文旨在探讨1例由疫苗株病毒引起成人水痘的病例,以提高对水痘疫苗二次传播的认识。从1名23岁女性水痘患者皮肤水疱中采集水疱液,接种至人胚胎成纤维细胞,3d后观察到细胞发生病变效应。用水痘-带状疱疹病毒gE`糖蛋白单克隆抗体间接免疫荧光法鉴定,结果阳性。测序分析显示,分离到的毒株其疫苗相关的单核苷酸多态性位点与Oka疫苗株一致,为疫苗株病毒。回顾性调查显示,患者没有水痘史和疫苗接种史,病毒可能来自1名与患者直接接触的接种疫苗后发生带状疱疹的儿童。

The present paper aims to report a case of adult varicella attributable to the vOka vaccine,and to raise our awareness ofs econdary transmission through vaccination. The fluid of the skin lesions was aspirated and inoculated to human embryonic fibroblasts. The cytopathic effect (CPE) was observed 3 days later and identified by indirect immunofluorescence using monoclonal antibodies against glycoprotein E of varicella-zostervirus (VZV). The gene sequence date further revealed that the vaccine strain-associated single nucleotide polymorphisms of this isolate were the same as those included in the vOka vaccine. Both the woman and her parents denied previously having the varicella vaccine. A retrospective survey showed that the transmission may have come from a child with zoster following vaccination.
