美媒：巴西公布中国的”科兴疫苗”实验有效性

美国彭博新闻社官网1月7日报道：在巴西进行的后期试验中，中国科兴生物科技有限公司(China’s Sinovac Biotech Ltd.)开发的实验疫苗，对新冠病毒的有效率为78%。这是迄今为止疫苗效力最明确的结果，此前的数据引发了”混淆和怀疑”(the most definitive result so far on the shot’s efficacy after previous data sparked confusion and doubt)。

报道称，巴西圣保罗州官员证实，这一保护率来源于中科国际在巴西进行的”最近最后阶段试验”(most advanced final-stage trials)，约有13000名参与者参与了实验。这一有效比率低于辉瑞公司(Pfizer Inc.)和摩德纳公司(Moderna Inc.)研发的mRNA疫苗约95%的有效性。

报道说，与中科国际合作在当地生产疫苗的Butantan研究所所长迪马斯·科瓦斯(Dimas Covas，图2右)表示，该疫苗在”预防轻度新冠病毒病例”(preventing mild cases of Covid-19)方面的有效率为78%，对”对抗重度和中度感染的有效率为100%”(and 100% effective against severe and moderate infections)。他说，该研究所计划在本周五向巴西监管机构申请紧急使用许可。监管机构，即Anvisa，有大约10天的时间来分析相关请求。

报道说，科瓦斯瓦表示，”试验中约有220名受试者受到感染，其中安慰剂组(注：没有药物成份)有160人，接种疫苗的受试者中有近60人”(The trial saw about 220 participants infected -- 160 in the placebo group and almost 60 among those who received the vaccine)。官员们拒绝提供更详细的研究细目，包括年龄组和注射副作用的信息，也没有具体说明完整的文件何时公布。

报道说，像其他一些疫苗一样，这种疫苗也要分两次注射，间隔14天。科瓦斯说，Butantan研究所”正在考虑将疫苗间隔28天，以便让更多的人尽快进行首期接种。”

报道说，由于巴西病毒死灰复燃，圣保罗州州长若奥·多里亚(Joao Doria，图2左)正试图加快疫苗接种速度，而中央政府推迟提出具体的疫苗接种日期。近1100万剂科兴冠狀病毒疫苗(CoronaVac)已经运抵巴西。

报道称，从上个月的实验中得到的”相互矛盾和不完整的信息”(Conflicting and incomplete information)，使人们对科兴疫苗在保护人民方面究竟有多有效产生了困惑。巴西的研究人员在12月下旬推迟了兴疫苗的完整数据的发布，只说它的有效性超过了50%。但圣保罗州卫生部长让·戈林施泰恩(Jean Gorinchteyn，图2中)随后表示，”疫苗没有达到90%的疗效”。更让人困惑的是，土耳其表示，其试验显示，估计有效率为91.25%，尽管这是基于只有29例实验。

这篇报道的标题是《Sinovac’s Covid Shot Proves 78% Effective in Brazil Trial》(在巴西试验中，科兴疫苗注射剂验证有效性为78%)。

只有少数几个当代的计算机科学家，例如麻省理工的JoshTenenbaum教授在认真尝试将这类自组织纳入人工智能。JoshTenenbaum和他的同事们正在研究“虚拟宝贝项目”---这个项目是能在现实世界中自动产生数百万想法和形象的能力。然后呐，这些内生的数据充当着系统其余部分学习的基础，无须提供任何额外的外部数据。根据这一根本观点，甚至出生前，我们大脑的核心回路就是通过自组织的建立，通过从产生于系统内部的数据库中自我提取而形成的。大部分原始的基础工作 是发生在内部的，没有任何外部世界的参与；只剩下最终的判断需要学习，需要我们从环境中接收到的额外的数据来塑造。

Homework today:

Material:

A middle-aged woman approached memory specialist for help with a problem .She claimed she was able to recount every day of her life since her teenage years with perfect clarity. If asked when she had first driving lesson, she would be able to recite back exactly what day it happened on, what she was wearing, what she did leading to the event, and everything else happened on that day.

The specialist was far away convinced that she actually had such super memory powers with a considerable number of tests, including brain scan and quizzing about historical data, they had to admit she could do exactly what she said she could.

My opinion:

This is kind of mental disease comes with some drawbacks. One of the biggest drawbacks for those with hyperthymesia is that they can remember the worst days of their lives in sharp detail. The expression “time heals all wounds” can not apply to them. They relive traumatic events, like losing a loved one as if they are happening again for the first time. Come to the woman, she has started that she still feels bad about things that happened to her over 30 years ago, and although her husband passed away about a decade ago, she often relives the day he died even though she would prefer not do.

Actually, this kind of people have no special abilities for remembering facts that are un related to their own lives. For example, some like this woman would be able to tell you the exact day on which an episode of a television show first time aired as long as she watched. But if asked to memorize a list of words, would be unable to recall the information any better than someone without the condition.

At the final of the class, I was asked “ if you could learn a super mental ability, what would you like to be able to do?”

I think I would like to have power of the “selective recall”, I hope I can filter some traumatic events automatically.
