Solid-Phase Synthesis and Immunological Evaluation of Peptide Conjugates Containing Stereochemically Defined UPam-Based TLR2 Ligands and Epitopes from SARS-CoV-2 Virus

T and B cell responses, as evidenced by elevated IgG production. These findings underscore the potential of chirally pure UPam-conjugated peptide vaccines to induce balanced, durable immunity against SARS-CoV-2 by combining TLR2-mediated adjuvanticity with precise epitope targeting.
