Use requires production of modified mRNA containing pseudouridine. Downstream performance in the review context is discussed together with delivery systems such as LNPs.; must be incorporated as a nucleoside modification in the mRNA construct
The supplied payload does not state that pseudouridine alone solves delivery, formulation, or route-of-administration challenges.
