由于诱导中和抗体的抗原表位恰好位于其包膜抗原E2蛋白的高变区1(HVR1),因而容易逃避机体的免疫监视,形成慢性感染,同时造成发展广谱预防性疫苗的困难。
The epitope inducing neutralizing antibody in high variable region 1 ( HVR1 ) is the reason for escape of host immune surveillance , evolution of chronic infection , and also difficulty of producing wide spectrum vaccine .
