基因免疫是指将编码特异抗原的目的基因重组表达载体直接接种到宿主组织内，在体内表达基因产物，进而激发宿主产生特异性免疫反应。自１９９０年首次报道发现基因免疫以来，这一新的免疫技术已经在基础免疫学研究和疫苗研制等许多领域得到广泛应用。对许多疾病（如流感）... Gene immunization is the direct expression of the target gene encoding the specific antigen into the host tissue to express the gene product in vivo to stimulate the host to produce a specific immune response. Since the first report of the discovery of genetic immunity in 1990, this new immunization technology has been widely used in many fields, including basic immunology research and vaccine development. For many diseases (such as flu) ...
