Genomic Insights into Monkeypox Virus: Paving the Way for Targeted Vaccine Development and Therapeutic Targeting
Abstract
Monkeypox virus (MPXV), a zoonotic orthopoxvirus, has emerged as a growing global health concern due to its expanding geographic spread and sustained human-to-human transmission. Advances in whole-genome sequencing have enabled detailed characterization of the MPXV genome, revealing a conserved central region essential for replication and variable terminal regions associated with host adaptation, immune evasion, and virulence. Comparative genomic analyses distinguish the more virulent Congo Basin (Clade I) lineage from the less severe West African (Clade II) lineage, reflecting differences in transmission dynamics and clinical outcomes. Integrating genomic data with structural and immunological insights has facilitated the identification of conserved viral targets for vaccine and therapeutic development, including monoclonal antibodies directed against key antigenic determinants. In parallel, next-generation vaccine platforms such as mRNA, DNA, and recombinant viral vectors are advancing MPXV prevention strategies and complementing existing orthopoxvirus vaccines. These innovations offer improved safety, scalability, and adaptability to emerging variants. This review highlights the interplay between viral genomics, evolution, and host immune responses, underscoring their importance in guiding rational vaccine design and targeted therapeutics. Continuous genomic surveillance and multidisciplinary research efforts remain critical for improving outbreak preparedness and mitigating the public health impact of MPXV.
