莫德纳(Moderna, Inc.)股价今日盘中大涨5.04%,引发市场广泛关注。这一显著涨幅源于公司宣布其mRNA流感疫苗mRNA-1010在关键3期临床试验中取得重大进展。
根据莫德纳公布的数据,在针对50岁及以上成年人的研究中,mRNA-1010相比传统获批流感疫苗的效力提升了26.6%。这项临床试验涉及11个国家的40,805名受试者,结果显示mRNA-1010对三种主要流感毒株均展现出强效保护。具体而言,对A/H1N1、A/H3N2和B/Victoria系流感病毒的相对疫苗效力分别达到29.6%、22.2%和29.1%。安全性方面,不良反应以轻微为主,与2023年的试验数据保持一致。
这一突破性进展不仅验证了mRNA技术在流感预防领域的潜力,还为莫德纳开发流感/COVID-19联合疫苗铺平了道路。公司首席执行官Stéphane Bancel强调,mRNA流感疫苗的核心优势在于可以更精准地匹配流行毒株,为应对未来可能的流感大流行提供快速响应能力。业内分析指出,这一成果可能重塑疫苗行业格局,为传统疫苗企业带来技术迭代压力。随着监管机构推动疫苗审批体系改革,莫德纳的积极临床数据或将成为突破监管壁垒的关键。这一进展不仅可能加速mRNA流感疫苗的上市进程,还有望推动更多创新型联合疫苗的开发,开启流感防控的新纪元。
