PseudoUridine Modified RNA in Vaccine R&D

The introduction of pseudouridine or N1-methyl pseudouridine into mRNA may be effective in reducing the immunogenicity of mRNA vaccines, enhancing the stability of mRNA, and enhancing its protein expression. Two new crown mRNA vaccines currently on the market include mRNA-1273 (Moderna) and BNT162b2 (Pfizer-BioNTech), both of which use N1-methyl pseudouridine triphosphate (m1ψTP) instead of uridine triphosphate (UTP). In contrast, German vaccine giant CureVac's new crown mRNA vaccine CVnCoV has a low efficacy of 48%, which the researchers speculate may be due to the fact that CVnCoV does not use modified nucleosides. The use of pseudouridine or N1-methyl pseudouridine substitution may become a trend in mRNA vaccine production, with potential applications in infectious disease prevention and cancer therapy.
