Double recombinant nOPV2 vaccine

🔗 原文链接

💡 AI 核心解读

通过双重组技术提高nOPV2疫苗的遗传稳定性,降低病毒重组导致疫苗失效的风险,为脊髓灰质炎根除提供更安全的疫苗方案

📝 英文原版摘要

<p>Nature Microbiology, Published online: 19 January 2026; <a href="https://www.nature.com/articles/s41564-025-02228-9">doi:10.1038/s41564-025-02228-9</a></p>The release of a more genetically stable form of a live, attenuated oral polio vaccine, nOPV2, was heralded as a major advance towards global polio eradication. Virus recombination events can undo all the hard work.
