We underscore molecular similarities (e.g., NF-κB activation, T-cell exhaustion) and clinical ramifications for high-risk individuals, stressing the necessity for interdisciplinary research to alleviate dual viral risks. EBV, a well-known oncogenic virus, has been linked to numerous malignancies, including lymphomas, nasopharyngeal carcinoma, and gastric cancer. Through the production of viral proteins that interfere with immune evasion, cellular signaling, and genomic integrity, it encourages malignant transformation and ultimately results in unchecked cell proliferation. Because of its capacity to induce tissue damage, immunological dysregulation, and chronic inflammation, COVID-19, which is brought on by the SARS-CoV-2 virus, has become a possible carcinogen. The virus's influence on cellular pathways and its long-term effects on the immune system may raise the chance of malignancy, particularly in people with pre-existing vulnerabilities, even if direct correlations to cancer are still being investigated. When two viruses co-infect a host, the review highlights the possibility of synergistic effects that could hasten the development of cancer. It describes how overlapping mechanisms like inflammation, immune suppression, and viral reactivation may be used by a combined EBV and COVID-19 infection to exacerbate carcinogenic processes.

These features highlight the significant evolution of MPXV in terms of host adaptation, transmission efficiency, and immune escape ability. The aim of this paper is to provide insights into the viral adaptive evolutionary mechanisms driving this global outbreak, with a particular focus on the role of immune escape (e.g., novel mechanisms of M2 proteins targeting the T cell co-stimulatory pathway) in enhancing viral transmission and pathogenicity. At the same time, we systematically evaluate the cross-protective efficacy and limitations of existing vaccines (ACAM2000, JYNNEOS, and LC16), as well as recent advances in novel vaccine platforms, especially mRNA vaccines, in inducing superior immune responses. The study further reveals the constraints to outbreak control posed by grossly unequal global vaccine distribution (e.g., less than 10% coverage in high-burden regions such as Africa) and explores the urgency of optimizing stratified vaccination strategies and facilitating technology transfer to promote equitable access. The core of this paper is to elucidate the dynamic game between viral evolution and prevention and control strategies (especially vaccines). The key to addressing the long-term epidemiological challenges of MPXV in the future lies in continuously strengthening global surveillance of viral evolution (early warning of highly transmissible/pathogenic variants), accelerating the development of next-generation vaccines based on new mechanisms and platforms (e.g., multivalent mRNAs), and resolving the vaccine accessibility gap through global collaboration to build an integrated defense system of \"Surveillance, Research and Development, and Equitable Vaccination,\" through global collaboration to address the vaccine accessibility gap.</p>","PeriodicalId":49328,"journal":{"name":"Viruses-Basel","volume":"17 9","pages":""},"PeriodicalIF":3.5,"publicationDate":"2025-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12474419/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145179968","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
