POLYNUCLEOTIDES AND LENTIVIRAL VECTORS EXPRESSING NON-STRUCTURAL ANTIGENS OF A FLAVIVIRUS SELECTED FROM THE GROUP OF DENV, ZIKV AND YFV, INDUCING PROTECTIVE CD8+ T-CELL IMMUNITY IN A HOST

Abstract

The invention relates to recombinant polynucleotides encoding at least a recombinant polynucleotide expressing at least a first fusion polypeptide that comprises MHC class I T-cell epitopes suitable to elicit a T cell immune response in a host in need thereof, wherein the MHC class I T-cell epitopes originate from a plurality of antigens wherein the antigens comprise at least non-structural antigens and are from at least one flavivirus selected from the group of 10 Dengue virus (DENV), ZIKA virus (ZIKV) and Yellow Fever virus (YFV). The invention also relates to the polypeptides comprising polyepitopes of said antigens encoded by the recombinant polynucleotides.
