Dec 17, 2020 · Recent technological advancement has largely overcome the main challenges in the development of mRNA vaccines. The Challenges 1. Instability. Protein expression after the vaccine is administered might be insufficient if, for instance, the half-life of the vaccine is too low, or if in vivo mRNA translation is insufficient 11,12. 2. Structural features of the mRNA—the U in the code, its single-stranded shape, ribose sugar and its specific sequence—ensure that the mRNA has a short half-life. These features combine to ...COVID-19 Vaccines Breathe Life into Research Done 20 Years Ago.
