Synthetic modified vaccinia Ankara (SMVA) based coronavirus vaccines

Abstract

Synthetic MVA-based vaccine compositions for preventing or treating a virus infection such as a coronavirus infection and methods of producing the vaccines. The vaccine compositions include (i) either a single DNA fragment that includes the entire genome of MVA, or two or more DNA fragments, each including a partial sequence of the genome of the MVA such that the two or more DNA fragments, when expressed in the host cell upon co-transfection, are assembled sequentially and comprise the full-length sequence of the MVA genome, and (ii) one or more DNA sequences encoding one or more human coronavirus antigens, subunits, or fragments thereof inserted in one or more insertion sites of the MVA. The antigens, subunits, or fragments thereof are expressed in the host cell upon transfection of the one or more DNA fragments.
