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 attenuated by propagation in cell culture in vitro by direct inoculation of the cell cultures with a human clinical specimen containing the virus.
摘要:
Hepatitis A virus is attenuated in virulence by in vitro passage in susceptible cell cultures, without prior passage in a subhuman primate. This process results in a live, attenuated hepatitis A virus vaccine suitable for human disease prevention.
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.

摘要:
Herpes Zoster, or varicella related post herpetic neuralgia is alleviated by immunizing people at risk of developing herpes zoster with varicella zoster virus (VZV) antigen.
摘要:
A live, attenuated varicella zoster virus vaccine is produced with enhanced yield of VZV. The new process makes mass production of a live VZV vaccine more practical. In addition, optimized monoloyer cell culture conditions provide a process for maximizing monolayer cell density which is useful for enhancing viral vaccine production. According to this process, cell densities approaching 500,000 cells/cm.sup.2 are routinely achieved in conventional culture vessels.
