To address this need, we developed four candidate vaccine antigens based on conserved sequences of the MPXV A35R and M1R proteins utilizing a lipid nanoparticle (LNP) delivery system. All four vaccine candidates elicited varying degrees of humoral and cellular immune responses and conferred differential protection against MPXV and vaccinia virus (VACV) in BALB\/c mice; notably, the dual\u2010antigen vaccines MV1 and MV2 induced more potent immunogenicity, including higher neutralizing antibody titers and cytokine secretion levels. However, among the four candidates, only the dual\u2010antigen vaccines MV1 and MV2 conferred protective efficacy in AGB6 mice and reduced infection\u2010induced pox lesion formation, indicating that antigens containing both intracellular mature virus (IMV) and extracellular enveloped virus (EEV) targets may be key to exerting robust protection. Notably, MV2\u2014which was designed via structural truncation and recombination based on poxvirus\u2010broad\u2010spectrum antibodies using the AlphaFold3 prediction platform and adopts a single\u2010chain \u201cdimer\u2010like\u201d configuration\u2014exhibited not only optimal protective efficacy but also sustained durable immune responses and protection. These findings indicate that MV2 induces favorable immunogenicity and has potential for preventing MPXV and VACV infections, supporting its promise as a clinical vaccine candidate for MPXV.<\/jats:p>","DOI":"10.1002\/mco2.70614","type":"journal-article","created":{"date-parts":[[2026,1,23]],"date-time":"2026-01-23T06:50:32Z","timestamp":1769151032000},"source":"Crossref","is-referenced-by-count":4,"title":["An
