In recent years, numerous studies have demonstrated the outstanding abilities of mRNA to elicit potent immune, making it a viable new platform for vaccine development
1). Additionally there are reports on incorporation of modified nucleobases into mRNA offering advantages for the generation of potent and long-lived antibody responses. In protein biosynthesis, 1-methylpseudouridine (m
1Ψ) and pseudouridine (Ψ) [
P2939 (synthetic)] [
P2396] are read like uridine (U) and enable comparatively high protein yields. Furthermore, m
1Ψ enhances immune evasion, protein production, and consequently vaccine efficacy.
