Disclosed are the methods of curing HBV infection and providing complete protection against HBV infection in a simplified HBV immunization schedule. The mechanistic basis for curing HBV infection is founded on the understanding that hepatitis B virus infection is established and prolonged by new rounds of infection with continuously produced viruses, which are not fully neutralized because of insufficient endogenous neutralizing antibodies. The methods of curing HBV infection including chronic HBV infection are aimed to block new rounds of HBV infection. The guidelines for establishing treatment regimens for curing HBV infection, include production or administration of sufficient level of HBV neutralizing antibodies in treated patients. Among the many different possibilities contemplated, the sufficient level of HBV neutralizing antibodies is expressed and maintained by the single injection of the HBV therapeutics that comprises non-replicating viruses or vectors encoding HBV neutralizing antibodies or by multi-injection of exogenous HBV neutralizing antibodies.
