The development of mRNA vaccines against COVID-19 has showcased the potential of RNA-based approaches, generating significant enthusiasm and investment in the field. RNA-based therapeutics offer new potential treatments for a range of diseases, taking advantage of the natural role of RNA in gene expression and allowing for targeted gene regulation and protein synthesis. In this blog, we will explore the types of RNA-based therapeutics, their advantages and limitations, and the current state of research in the field. But first, let’s define what an RNA molecule is.
