As the increasingly develepoment of mRNA stability and delivery systems,the mRNA vaccine has made rapid progress in the individualized tumor vaccine in recent years. Due to its simple production process,expression the antigens in cells,and security features is superior to DNA vaccine,mRNA is a new form of vaccine promising alternative to attenuated and inactivated vaccine and protein vaccine. In order to understand the development and research status of global mRNA vaccine,the molecular design,delivery system and clinical research status of mRNA vaccine were analyzed and summarized,providing r...
