现代疫苗大都基于所选定的特定单一分子的靶抗原以诱导保护性免疫反应 ,但通常这样的分子疫苗免疫原性都较差 ,急需开发合适的疫苗投递系统投递疫苗抗原以诱导有效的保护性免疫反应 ,因此近十年来开发疫苗投递系统的研究成为疫苗研究领域的研究热点 ,本文就这方面的研究进展作一综述 Modern vaccines are mostly based on the specific single molecule target antigen selected to induce a protective immune response, but generally such molecular vaccines are poorly immunogenic and it is imperative to develop suitable vaccine delivery systems to deliver vaccine antigens to induce effective protection Immune response, so the development of vaccine delivery system in recent ten years has become a research hotspot in the field of vaccine research. This article reviews the research progress in this field
