摘要： The present disclosure provides, in part, a priming and boosting vector-based platform to develop vaccines against pathogensthat is tailored to elicit a broad T cell response targeting conserved viral epitopes. The universal vaccines are prepared against an immunogen of an infectious pathogenic organism selected from a virus, a bacteria, a fungus or a protozoan comprising at least one ribonucleic acid (RNA) polynucleotide comprising an open reading frame encoding at least one polypeptide antigen or an immunogenic fragment thereof, wherein the polypeptide antigen, or the immunogenic fragment thereof, comprises a conserved internal protein that is enriched in CD8+ T cell recognition antigens. The effectiveness of the priming and boosting platform is tested in a humanized mouse model comprising a fully functional human immune system.
