Longer retention of the nanoparticle-bound antigens within lymph nodes and better presentation of the antigens to antibody-producing lymphocytes.   This technology is very welcome news.   https://www.biorxiv.org/content/10.1101/2021.03.26.437274v1.full.pdf+html   #CoVid #vaccine #nanotechnology #variants
