Chinese vaccine doesn't look that hot https://www.sciencemag.org/news/2021/01/brazil-announces-fantastic-results-china-made-covid-19-vaccine-details-remain-sketchy In a formal presentation of the data at Butantan today, Covas made no mention of case numbers, saying the data will be reported in a scientific publication and to Brazilian regulators. But when pressed by journalists, he allowed that there were 218 cases of mild disease. “The exact number is 160-something in the placebo group and less than 60 in the vaccinated group,” he said. (This would equal 63%, not 78%, efficacy.) CoronaVac appeared to work as well in the elderly as in other age groups, the researchers added. The lack of data—let alone the efficacy discrepancy—predictably led to immediate skepticism. “Until they show us these numbers, it is nothing more than an empty announcement,” tweeted epidemiologist Denise Garrett, a vice president of the nonprofit Sabin Vaccine Institute. Details have been in short supply in the initial efficacy trial announcements by other COVID-19 vaccinemakers as well. But a researcher who runs one of the 16 sites conducting the CoronaVac trial in Brazil, Esper Kallas at the University of São Paulo’s main campus, says even study investigators still don’t know all the data. Kallas, who spoke with Science after the press conference, is “happy” about the results. “We know the 78% is true,” he says. But he is frustrated that “we don’t have the granularity of it.” As for the case numbers Covas mentioned, Kallas says, “I couldn’t understand those figures.” 他们的数据为什么这么讳莫如深？连study investigator都不知道？

他们的数据为什么这么讳莫如深？连study investigator都不知道？
应该是106%。
哈哈哈哈 二楼总是神回复🤓
真幽默
这个病毒的传染性，63%有效即使100%覆盖都没法阻断传播。
1、疫苗和安慰剂的人数比例不是1：1，不过这个很奇怪，clinicaltrials.gov上面明确说的是1：1 2、把土耳其和印尼的数据拿过来合并之后的有效性 3、78%是某一个cut off date分析数据的时候得到的有效性，在这之后又出了一些新的确诊
先别急着下结论，耐心等待完整的数据吧，没有数据大家都是瞎猜
科兴不公布数据呀。
等正式发表，起码几个月吧
mm 知道为什么不给老人用吗？我前两天看了你的帖子给我爸妈说 要打就打科兴的，结果他们给我说60以上老人不给打。为什么？以前也觉得他们不用打，可是现在情况好像有严峻了。哎。
醫藥資料不比晶片
可以 磨皮
路透社在两天前报道78%有效率时最初也有要报道一半一半的迹象，谷歌搜索结果现在还有但点进链接已经把“一半”这个数字删掉了。
两天前宣布78%时香港媒体也有提到疫苗组和安慰剂组的人数比例是一半一半。
如果用一半人数来计算就是63%，为什么调整了人数比例到目前为止巴西方面没有解释。
直接去问巴西卫生部啊。他们的总统号称巴西川普，大川粉，反正连同总统儿子一起反华的厉害。再说，你又不打科兴的疫苗，63%还是78%有什么可在乎的。反正都不如辉瑞95%。
你爸妈说的60岁以上不给打可能是国药的疫苗。科兴的疫苗3期刚有几个国家出来结果中国还没有正式批准对大众使用吧？
什么叫不知道正常？
都公布结果了还不知道内情？独一家
俄罗斯的都公布了
巴西總統也確診 應作何反思
别混淆，国内喜欢把巴西总统贴标签成川粉。
不过这个是卫生部的，巴西总统倒是说过数据不好
亲戚里国内当医生的已经打了
那是内部打，对普罗大众打国家应该有正式批文吧？
党说有效就有效，请相信党和国家，凡事都是为你好。
这个有点猫腻
巴西也是联邦制呀，管不到各州，你没有亲友在国内吗？
估计老实公布了各期数字，怕63都没有
学了牛津疫苗
嗯，有这几种可能，等数据看看吧
其实都一样……
这种计算方式很容易有操作空间，比如土耳其的数据就很可疑
不要拿批文當藉口
七大中常委要不要打
還不是一句話
我信任传统苗，但在海外我也打不着啊，所以科兴苗到底是63还是78%对我也没区别。而对我国内的家人，一直喊他们尽快去打国产苗，但也还轮不上，况且国内也没有其他选择。
要是灭活疫苗保护率只有63%，免疫期只有几个月，你怎么选？几个月再打一次吗？
日本的 小兒麻痺 減活疫苗
沙賓疫苗則可能引起疫苗相關麻痺型小兒麻痺症，大約每一百萬人中會出現三位這種症狀。
也就是說 十四億人打下去 會有 四千兩百人得病
牛！
大哥/姐，您先研究一下传统疫苗的副作用再“信任”呗！
喔对了，FYI，针对冠状病毒没有“传统”疫苗喔～
国内疫苗躲过了老人和高危人群，比如有各种慢性病的。欧美疫苗是老人和高危人群优先，但是国内是老人和高危人群不能打。
这个比较靠谱 国内目前注册网站，根本查不到科兴疫苗，只有一个国药，还是中期数据的。。 这些国内疫苗真的恐怖，注册都没有。。
好多人无条件的相信传统疫苗有问题🤨 也不知道为什么
那么多年打下来了
大家不是怀疑灭活疫苗，是怀疑国产疫苗，毕竟名声不大好，再说冠状病毒的灭活疫苗效果一直不大好，到了新冠怎么突然就好了呢？
