  • Publication number: 20230346924
    Abstract: The present invention relates to an mRNA vaccine comprising an adjuvant of which an immune activating function is kinetically controlled and, more specifically, to an mRNA vaccine comprising an adjuvant characterized in that, after mRNA is transcribed into proteins, the activating function of the adjuvant is sequentially active. The present invention relates to a key technology for optimizing the time interval between mRNA antigen expression and immune activation in order to effectively control antigen expression and antigen immunogenicity, which conflict. In order to optimize an mRNA antigen expression amount and the active time of an adjuvant, the present invention provides a key technology, which kinetically controls the action of an immune activating substance to increase the expression amount and immunogenicity of an antigen at the same time, and thus remarkably increases the efficacy of an mRNA vaccine.
