Fig. 1. Mechanism of action of mRNA vaccines.

Fig. 1

mRNA vaccines to prevent COVID-19 were developed by encapsulating chemically modified mRNAs in lipid nanoparticles. After endocytosis, mRNA can be delivered into the cytoplasm, resulting in the induction of antigen expression. The antigens translated by mRNA vaccines can induce both cell-mediated and antibody-mediated immunity. MHC, major histocompatibility complex; TAP, The transporter associated with antigen processing.
