Summary: Here, we present a protocol for the development of mRNA-loaded lipid nanoparticle (LNP) vaccines for target antigen sequences of interest. We describe key steps required to design and synthesize mRNA constructs, their LNP encapsulation, and mouse immunization. We then detail quality control assays to determine RNA purity, guidelines to measure RNA immunogenicity using in vitro reporter systems, and a technique to evaluate antigen-specific T cell responses following immunization. : Publisher’s note: Undertaking any experimental protocol requires adherence to local institutional guidelines for laboratory safety and ethics.
