ABSTRACT
Current RNA vaccines against severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) are limited by instability of both the RNA and the lipid nanoparticle delivery system, requiring storage at -20°C or -70°C and compromising universally accessible vaccine distribution. This study demonstrates the thermostability and adaptability of a nanostructured lipid carrier (NLC) delivery system for RNA vaccines that has the potential to address these concerns. Liquid NLC alone is stable at refrigerated temperatures for ≥1 year, enabling stockpiling and rapid deployment by point-of-care mixing with any vaccine RNA. Alternatively, NLC complexed with RNA may be readily lyophilized and stored at room temperature for ≥8 months or refrigerated temperature for ≥21 months while still retaining the ability to express protein in vivo. The thermostability of this NLC/RNA vaccine delivery platform could significantly improve distribution of current and future pandemic response vaccines, particularly in low-resource settings.
