科技日报北京 7 月 30 日电 (记者付丽丽)“建立严格的法律责任制度,对违反《疫苗管理法》规定构成犯罪的,依法从重追究刑事责任,货款不足 50 万元的按 50 万元计算。”30 日,在国家药监局主办的 “《疫苗管理法》颁布法规解读宣贯研讨会上”,该局政策法规司副司长吴丽雅说。《疫苗管理法》是全球首部综合性疫苗管理法律。具体来讲,吴丽雅介绍,生产、销售的疫苗属于假药的,没收违法所得和违法生产、销售的疫苗以及专门用于违法生产疫苗的原料、辅料、包装材料、设备等物品,责令停产停业整顿,吊销药品注册证书,直至吊销药品生产许可证等,并处违法生产、销售疫苗货值金额 15 倍以上 50 倍以下的罚款。生产、销售的疫苗属于劣药的,处违法生产、销售疫苗货款金额 10 倍以上 30 倍以下罚款。吴丽雅为读者算了一笔账。生产、销售的疫苗属于假药的,最低罚款:50 万元 ×(15 倍至 50 倍)=750 万元至 2500 万元;生产、销售的疫苗属于劣药的,最低罚款: 50 万元 ×(10 倍至 30 倍)=500 万元至 1500 万元。疫苗是特殊的药品,事关公共安全。吴丽雅表示,长春长生问题疫苗事件暴露出我国在疫苗监管方面存在主体责任不落实、质量安全管理不到位、职业化专业化监管力量薄弱等问题。鉴于此,《疫苗管理法》明确提出国家对疫苗实行最严格的管理制度,对疫苗的研制、生产、流通、...

近日,来自 9 个国家的 33 名微生物学家在《自然综述:微生物学》上发文表示,应该进一步将微生物融入主流气候变化研究和气候变化框架中,以应对人为造成的气候变化问题。他们警告说,“提醒人类注意,气候变化的影响将严重依赖微生物的反应,它们对于实现一个环境可持续发展的未来至关重要”。已知人类活动及其对气候和环境的影响关系到动植物灭绝和生物多样性损失,并且危及地球上的动植物生命。微生物也会对温室气体排放产生重要影响。尽管微生物丰富多样,但它们维护生态系统健康的作用,以及如何影响气候变化或被气候变化影响,却鲜为人知。澳大利亚新南威尔士大学的 Ricardo Cavicchioli 等人认为,微生物在气候变化生物学中扮演的核心角色及其全局重要性不应被低估,他们并且呼吁研究人员、机构和政府对微生物加剧或缓解人为气候变化影响的作用进行评估。研究人员在文中探讨了气候变化对微生物作用以及全球海陆生物群落的影响。他们还指出,从农业和传染病的角度出发,需要更深入地理解气候变化对微生物的影响,比如气候变化预计将提高部分人类病原体的抗生素耐药性。相关论文信息:https://doi.org/10.1038/s41579-019-0222-5

据新华社电 美国疾病控制和预防中心研究团队发现,正在刚果(金)使用的两种试验性疗法对抗击当前的埃博拉疫情有效。7 月 9 日发表在英国《柳叶刀—传染病》杂志上的研究显示,在实验室中,抗病毒药物 Remdesivir,以及由三种抗体组成的抗埃博拉药物 ZMapp 可阻断新一轮埃博拉疫情的致病毒株在人类细胞中增长。确认抗病毒药物有效的关键之一在于找到此次疫情的致病毒株。论文第一作者、美疾控中心微生物学家劳拉 · 麦克马伦说,目前在刚果(金)试用的疗法均针对以前疫情中获取的埃博拉毒株,而埃博拉是一种核糖核酸(RNA)病毒,会不断变异,因此确定现有疗法是否对新毒株奏效至关重要。美疾控中心研究人员没有当前在刚果(金)传播的 “伊图里” 毒株样本,但他们从开源基因库中获得病毒序列数据,使用 “反向遗传学” 技术重组了毒株。这项技术有助于研究人员更多了解新毒株在埃博拉家族树中的位置,从而寻找更多潜在疗法,并测试各类新疗法的有效性,还可与未来的新毒株进行比对。研究中还发现,2014 年到 2016 年西非多国爆发埃博拉疫情期间开发的一种实验室病毒诊断方法可用于诊断 “伊图里” 毒株。(周舟)文章摘自:生物360
