Genetically-engineered phage particles displaying a defined epitope of SARS-CoV-2 spike protein can elicit a systemic immune response. Candidate epitopes may be assessed through various genetic and structural studies to determine feasibility as a universal epitope for protection against existing and emerging viral variants. In this artistic depiction, created in collaboration with Christopher Markosian and Daniela Staquicini, phage particles (pale blue) display multiple copies of the spike protein-derived C662–C671 epitope (pink), which elicit the generation of antibodies (yellow) immunoreactive against spike protein. SARS-CoV-2 is shown at bottom right in magenta and purple.
