Scientists from The Wistar Institute, the University of Pennsylvania, the Icahn School of Medicine at Mount Sinai, Saint Joseph’s University (Philadelphia, PA), and Inovio Pharmaceuticals (Plymouth Meeting, PA) have described a next-generation vaccination technology that combines plasmid DNA with a lipid nanoparticle delivery system. The team showed that these DNA lipid nanoparticles demonstrate a unique way of priming the immune system compared to mRNA and protein-in-adjuvant formulations and that these DNA lipid nanoparticles induced robust antibody and T-cell responses after a single dose. Importantly, these responses were durable, with memory responses in small animals persisting beyond a year after immunization.
