Enhancement of immunogenicity of SARS-CoV-2 spike protein expressed in Escherichia coli by fusion of the CRM197 functional domain

Enhancement of immunogenicity of SARS-CoV-2 spike protein expressed in Escherichia coli by fusion of the CRM197 functional domain

As an immunogenic non-toxic mutant of diphtheria toxin (DT), cross-reacting material 197 (CRM197) exhibits a significant immunogenicity-enhancing effect on various pathogenic vaccines. However, its application in vaccines against highly pathogenic pathogens remains underexplored. In this study, we i...
