The invention discloses HBV pre-c-Fc recombinant protein and a coding nucleotide sequence thereof and discloses a recombinant vector containing a coding sequence of the protein and a host cell. The invention further discloses a recombinant baculovirus, a method of obtaining the recombinant baculovirus, and a method of expressing the HBV pre-c-Fc recombinant protein in an insect baculovirus expression system, and also discloses a recombinant baculovirus containing a HBV pre-c-Fc coding gene and applications of the HBV pre-c-Fc recombinant protein in preparation of vaccines or medicines preventing or treating hepatitis B. After a BALB/c mouse is subjected to injection immunization with the HBV pre-c-Fc recombinant protein, detection shows that the generating amount of a hepatitis B virus core protein antibody in serum of the mouse is far higher than that in a situation that an antigen used for preparing hepatitis B vaccines in traditional methods is used.
