[Vaccine development based on RNA technology platforms].

mRNA vaccine technology has made significant progress in recent years, especially with the large-scale application driven by the COVID-19 pandemic. Moderna and Pfizer/BioNTech vaccines have become central tools in the global fight against the virus, demonstrating the potential of the mRNA platform for rapid design, production, and strong immune responses. These vaccines showcase the unique advantages of rapid response and effective protection. At the same time, mRNA technology still faces challenges, such as stability and targeted delivery. Future research will focus on improving the stability and safety of mRNA vaccine and expanding its application to more infectious diseases and cancer treatments. This article reviews platforms of mRNA vaccine, vaccine design, development of delivery system, and the application of mRNA vaccines, in order to enhance the understanding of professionals and accelerate the layout of this technology in vaccine research and application in China.
