所谓DNA疫苗,是指基因疫苗,也称为核酸疫苗。这种疫苗被认为是第三次疫苗革命。在这种疫苗里,核酸分子是一种细菌的质粒,在克隆了特异性的基因之后,能在真核细胞中表达蛋白质抗原,刺激机体产生特异的体液和细胞免疫反应。但是,有关DNA疫苗的详细免疫机制是什么,现在仍然 The so-called DNA vaccine, refers to the gene vaccine, also known as nucleic acid vaccine. This vaccine is considered the third vaccine revolution. In this vaccine, a nucleic acid molecule is a bacterial plasmid that, after cloning a specific gene, can express a protein antigen in eukaryotic cells to stimulate the body to produce specific humoral and cellular immune responses. However, what is the detailed immunological mechanism of DNA vaccination and is still there
