Researchers at Harvard’s Wyss Institute and Dana-Farber Cancer Institute report that a DNA origami-based vaccine platform called DoriVac generated robust immune responses in mice and in a human lymph node “Organ Chip” model. The team says the approach could be easier to store and manufacture than lipid nanoparticle–delivered mRNA vaccines, though the work remains preclinical. The results were published in Nature Biomedical Engineering.
