Also disclosed are various uses of said antibodies in the prevention and treatment of HBV infection. Peripheral blood lymphocytes obtained from human donors having a high titer of anti HBVsAg antibodies are activated in vitro with pokeweed mitogen and then fused with heteromyeloma cells to generate hybridomas secreting human antibodies having a high affinity and specificity to HBVsAg.
