The use of mRNA vaccines in the fight against SARS-CoV-2 during the COVID-19 pandemic, has demonstrated their enormous potential as a highly effective therapeutic modality and has led to a revolution in biomedicine. Since then, mRNA has also shown promise in the treatment of cancer, rare diseases, anaphylaxis, CRISPR-Cas9-based therapy and others. There are currently >100 clinical trials registered with mRNA being the drug substance. The technology to produce mRNA therapeutics can still be considered as being in the early stages of development, as multiple academic and industrial laboratories across the world invest significant funding and talent, with the intention to increase productivity and purity in the production of mRNA drug substance and lipid nanoparticles that would deliver affordable mRNA therapeutics. This article aims to present a technological paradigm of harnessing the potential of chromatography as a purification tool with high selectivity and scalability that are unmatched by other purification methods, as well as analytical technology that can provide timely and accurate information on the quality and quantity of the mRNA product, its precursors and side-products.
