    • A poly-antigenic HBV DNA vaccine is provided to induce excellently an antibody reaction and a cell mediated immunity by comprising genes coding a surface antigen of an HBV as well as a core antigen and a polymerase antigen, thereby capable of preventing and treating chronic B-type hepatitis. An HBV DNA vaccine for treating chronic B-type hepatitis comprises genes coding an HBsAg, an L-protein, a core and a polymerase antigen of an HBV, wherein at least one of the genes codes a codon-optimized antigen, the genes coding the HBsAg and L-protein are introduced simultaneously into one expression vector, and the genes coding the core antigen and polymerase are introduced simultaneously into another expression vector. The vaccine further comprises an immunological adjuvant. A method for preparing the HBV DNA vaccine comprises the steps of: (a) codon-optimizing a gene coding an HBsAg, an L-protein, and a core antigen of an HBV; and (b) introducing the codon-optimized gene coding the HBsAg, L-protein, and core antigen and a gene coding a polymerase of the HBV, which is codon-optimized or not codon-optimized, into at least one expression vector. A method for treating chronic B-type hepatitis comprises a step of administering the vaccine.
    • 提供多抗原性HBV DNA疫苗以通过包含编码HBV表面抗原的基因以及核心抗原和聚合酶抗原来极好地诱导抗体反应和细胞介导的免疫,由此能够预防和治疗慢性B- 型肝炎。 用于治疗慢性B型肝炎的HBV DNA疫苗包括编码HBV的HBsAg,L-蛋白,核心和聚合酶抗原的基因,其中至少一个基因编码密码子优化的抗原,编码 将HBsAg和L-蛋白同时引入一个表达载体中,将编码核心抗原和聚合酶的基因同时引入另一种表达载体。 疫苗还包含免疫佐剂。 制备HBV DNA疫苗的方法包括以下步骤:(a)密码子优化编码HBV的HBsAg,L-蛋白和核心抗原的基因; 和(b)将编码HBsAg,L-蛋白和核心抗原的密码子优化的基因和编码经密码子优化或未经密码子优化的HBV聚合酶的基因导入至少一个表达载体中。 一种治疗慢性B型肝炎的方法包括施用疫苗的步骤。
