CA3170743A1 — Multivalent nucleic acid based coronavirus vaccines

USPTO Abstract

The present invention is inter alia directed to compositions comprising at least one nucleic acid encoding at least one antigenic peptide or protein selected or derived from a Coronavirus membrane protein (M), nucleocapsid protein (N), non-structural protein, and/or accessory protein or an immunogenic fragment or immunogenic variant thereof. The composition may additionally comprise at least one nucleic acid encoding at least one antigenic peptide or protein selected or derived from a Coronavirus spike protein (S). The nucleic acid sequences of the compositions are preferably in association with a polymeric carrier, a polycationic protein or peptide, or a lipid nanoparticle (LNP). The compositions provided herein are for use in treatment or prophylaxis of an infection with at least one Coronavirus, and may therefore be comprised in a vaccine, preferably a multivalent vaccine. The invention is also directed to first and second and further medical uses and to methods of treating or preventing Coronavirus infections.
