Influenza poses a serious threat to global public health and causes serious economic los-ses. Vaccination is the most effective measure to prevent influenza. However, the mismatch between the vac-cine strain and the epidemic strain, which results from antigenic drift and antigen conversion of influenza vi-rus, often invalidates the conventional vaccine stockpiles. mRNA vaccine is a relatively safe platform com-posed of nucleic acid. Improvements in genetic engineering technology and novel delivery systems have great-ly promoted the research and development of mRNA vaccines against influenza. mRNA vaccines are promis-ing candidates for the rapid and efficient prevention of seasonal influenza epidemics and influenza pandemics.
