"美国卫生部长小肯尼迪突然砍掉5亿美元mRNA疫苗研究经费，理由竟是'对新冠流感无效'——这波操作让科学家集体炸锅！布里斯托尔大学教授怒斥'愚蠢至极'，牛津疫苗专家甩出数据打脸：'光辉瑞疫苗一年就救了600万人'。最搞笑的是，肯尼迪一边喊着要转向'更安全平台'，一边无视mRNA技术应对变异毒株的闪电研发速度。网友吐槽：'这哪是科学决策，分明是反疫苗教主在卫生部搞政变！'要知道心肌炎副作用发生率比中彩票还低，而传统灭活疫苗效果还不如mRNA，专家哀叹：'政治 pendulum 摆得太狠，医学进步要遭殃了'"

**US Health Secretary Robert F Kennedy Jr has axed 22 federally-funded mRNA vaccine projects worth $500m, claiming they"fail against respiratory viruses". The move - praised by anti-vaccine groups but condemned by scientists - shifts focus to traditional vaccine platforms amid ongoing debates about myocarditis risks and variant protection.**
美国卫生部长小罗伯特·肯尼迪砍掉了22个价值5亿美元的联邦资助mRNA疫苗项目，声称它们"对呼吸道病毒无效"。这一举动受到反疫苗团体赞扬但遭科学家谴责，在持续关于心肌炎风险和变异保护效果的辩论中，将重点转向传统疫苗平台。

**Oxford's Prof Andrew Pollard rebuts Kennedy's claims, noting mRNA vaccines saved ~6 million lives in COVID's first year."Balancing extremely rare side effects against massive benefits is essential," said the outgoing JCVI chair, highlighting mRNA's superior efficacy over inactivated vaccines in trials.**
牛津大学的安德鲁·波拉德教授反驳肯尼迪的说法，指出mRNA疫苗在新冠第一年拯救了约600万生命。"权衡极其罕见的副作用和巨大益处至关重要，"即将离任的疫苗接种与免疫联合委员会(JCVI)主席表示，强调mRNA在试验中优于灭活疫苗的效力。

**While all vaccines struggle with fast-mutating viruses like flu and SARS-CoV-2, experts warn abandoning mRNA's rapid adaptability - crucial during pandemics - would be"catastrophic". Bristol's Prof Adam Finn notes:"Swinging from overhyping to complete rejection is equally unscientific."**
尽管所有疫苗都难以应对流感和SARS-CoV-2等快速变异的病毒，专家警告放弃mRNA的快速适应性——在大流行期间至关重要——将是"灾难性的"。布里斯托尔的亚当·芬恩教授指出："从过度炒作到完全拒绝同样不科学。"

**The decision comes as Moderna's mRNA flu vaccine shows promise in trials, potentially cutting development time from 6 months to 30 days."Speed matters when viruses evolve," stressed Prof Pollard, noting traditional flu shots also require annual updates.**
这一决定出台之际，Moderna的mRNA流感疫苗在试验中显示出前景，可能将开发时间从6个月缩短至30天。"当病毒进化时，速度很重要，"波拉德教授强调，指出传统流感疫苗也需要每年更新。
