ABSTRACT:
Hepatitis-A virus, suitable for use in human or animal vaccines, is prepared by adapting the virus first to human kidney cells and subsequently adapting the thus-altered virus to human fibroblast strains. In the process the growth rate of Hepatitis-A virus on the noted tissues is materially increased. This HAV is also a useful antigen in diagnostic test procedures.
