ABSTRACT:
A humanized antibody of the present invention shows similar antigen-binding affinity to a mouse monoclonal antibody and significantly low immunogenecity. Therefore, the humanized antibody of the present invention can be effectively used for treating chronic hepatitis B and preventing HBV infection of a patient received liver transplantation and vertical transmission from a mother infected with HBV to a fetus.
