Prior infection and vaccination acted in concert to prevent the emergence of SARS-CoV-2 RNAemia and symptomatic infection. RNAemia levels remained consistent across both the Delta and Omicron variant phases. Cell-derived nanosized lipid bilayer structures, often referred to as cellular nanovesicles, are being explored as a potential platform to manage immune responses. Because of their remarkable biocompatibility, robust structural stability, and sub
