mRNA Vaccines Against Hantavirus

Abstract

One solution to the problem of Hantavirus pathology is design, production, and administration of a nucleic acid vaccine (NAV). In certain aspect the NAV is an mRNA vaccine. Certain embodiments are directed to the use of a polyprotein, which is cleaved to produce Gn (N-terminal) and Gc (C-terminal) glycoproteins, the Gn glycoprotein, the Gc glycoprotein, or the Gn and Gc glycoproteins hantaviruses as protective antigen(s) for development of hantavirus vaccines. The Gn/Gc protein, which is cleaved post-translationally to individual Gn and Gc proteins, can be used as an antigen for vaccines. In case of DNA and RNA-based vaccines, the complete M gene, which encodes the complete single open reading frame, which is cleaved post-translationally in the Gn and Gc proteins or individual open reading frames encoding either Gn or Gc, is used.
