疫苗之痛:缺失的监管,谁该担责?

背景材料:2018年7月15日,国家药品监督管理局发布通告指出,长春长生生物冻干人用狂犬病疫苗生产存在记录造假等行为;同时,该公司生产的批号为201605014-01的\"吸附无细胞百白破联合疫苗\"经中国食品药品检定研究院检验,其疫苗有效性不符合规定。此外,武汉生物制品研究所有限责任公司生产的批号为201607050-2的百白破疫苗因分装设备短时间故障,导致待分装产品混悬液不

监管与重罚:如何挽回被失信的民心?

主持人:从处罚结果来看,此次长春长生生物疫苗案件,吉林药监局收回其狂犬病疫苗药品GMP证书,停止该企业狂犬病疫苗生产及销售,暂停该企业所有产品批签发,并处以罚没款总计344.29万元。而对比美国一个疫苗产品出问题,企业会被罚得倾家荡产,同时受到监禁处罚。我国的处罚制度是否偏轻?将会带来什么后果

缺位与错位:“失灵的手”该伸向何方?

主持人:结合背景材料,请谈谈此次疫苗事件暴露了我国药品监管中存在着哪些问题?造成以上问题的根本原因是什么?朱为群:虽然外界对此次疫苗事件背后的具体监管情况缺乏信息,但有一点是肯定的,那就是监管机构是存在的,但是没有发挥作用。疫苗监管缺失的根本原因在于相关监管责任者缺乏对生命的起码敬畏,以及由此导致的监管机制的缺失和监管方式

JUNO Sensitivity on Proton Decay p→νˉK+p\to \bar\nu K^+ Searches

The Jiangmen Underground Neutrino Observatory (JUNO) is a large liquid scintillator detector designed to explore many topics in fundamental physics. In this paper, the potential on searching for proton decay in $p\to \bar\nu K^+$ mode with JUNO is investigated.The kaon and its decay particles feature a clear three-fold coincidence signature that results in a high efficiency for identification. Moreover, the excellent energy resolution of JUNO permits to suppress the sizable background caused by other delayed signals. Based on these advantages, the detection efficiency for the proton decay via $p\to \bar\nu K^+$ is 36.9% with a background level of 0.2 events after 10 years of data taking. The estimated sensitivity based on 200 kton-years exposure is $9.6 \times 10^{33}$ years, competitive with the current best limits on the proton lifetime in this channel

JUNO sensitivity on proton decay p → ν K + searches*

The Jiangmen Underground Neutrino Observatory (JUNO) is a large liquid scintillator detector designed to explore many topics in fundamental physics. In this study, the potential of searching for proton decay in the $p\to \bar{\nu} K^+$ mode with JUNO is investigated. The kaon and its decay particles feature a clear three-fold coincidence signature that results in a high efficiency for identification. Moreover, the excellent energy resolution of JUNO permits suppression of the sizable background caused by other delayed signals. Based on these advantages, the detection efficiency for the proton decay via $p\to \bar{\nu} K^+$ is 36.9% ± 4.9% with a background level of $0.2\pm 0.05({\rm syst})\pm$$0.2({\rm stat})$ events after 10 years of data collection. The estimated sensitivity based on 200 kton-years of exposure is $9.6 \times 10^{33}$ years, which is competitive with the current best limits on the proton lifetime in this channel and complements the use of different detection technologies
