重组型戊型肝炎疫苗I期临床试验初见成效戊型肝炎常见于发展中国家,根据血清学异常的情况,有人估计大约1/3的人感染过戊肝病毒,印度人一生中感染戊肝病毒的危险性超过60%。但是戊肝常常是自限性的,病变主要局限于局部,通过血清学检测难以发现,因此,真正的戊肝发病率难以估计。 Phase I clinical trial of recombinant hepatitis E vaccine has shown initial success Hepatitis E is common in developing countries. According to the serological abnormalities, it is estimated that about one third of people have been infected with hepatitis E virus and Indian people have been infected with hepatitis E The danger of the virus is over 60%. However, hepatitis E is often self-limiting. Lesions are mainly localized and difficult to detect by serological tests. Therefore, the true incidence of hepatitis E is difficult to estimate.
