    摘要: Hepatitis A antigen obtained from the livers of non-human primates infected with hepatitis A (infectious hepatitis) virus has been found to be usable in fast, simple assays for hepatitis A antibody and thus usable in diagnosis of hepatitis A disease in humans, and for the preparation of hepatitis A vaccine.

    摘要: Hepatitis A virus is passaged at least once in a susceptible sub-human primate; the infected liver from such passage is used to inoculate an in vitro cell culture, the inoculated cell culture is incubated until hepatitis A antigen is detected in the cell sheet or culture fluid, and at least two serial in vitro passages in cell culture are carried out. The hepatitis A virus so modified can be used to prepare live, attenuated hepatitis A vaccine or an inactivated hepatitis A vaccine.
