1. A vaccine composition, comprising a multivalent carrier associated with a plurality of coronavirus antigens, wherein the plurality of coronavirus antigens comprises a first coronavirus antigen of a first coronavirus strain and a second coronavirus antigen of a second coronavirus strain that is different from the first coronavirus strain,
wherein the first coronavirus antigen and the second coronavirus antigen each comprise an amino acid sequence having at least 80% sequence identity to an amino acid sequence selected from the group consisting of SEQ ID NOs: 1-12 and the amino acid sequences of the first and second coronavirus antigens are different from one another, and
wherein the multivalent carrier comprises a self-assembling nanoparticle.
