最新发现是,打了疫苗染病的携带同等量的病毒,和没打疫苗的相当 说明打了疫苗染了病毒,照样传染他人,疫苗只能有限的保护自己,减轻病重程度 Study: Vaccines don''t lower viral load in Delta breakthrough cases Tucker Reals Thu, August 19, 2021, 6:06 AM·3 min read A study by University of Oxford scientists has found that people who contract the Delta variant of COVID-19 after being fully vaccinated carry a similar amount of the coronavirus as those who catch the disease and have not been inoculated. Oxford''s lead researcher, Dr. Sarah Walker, told The Telegraph that the study shows two doses of the Pfizer/BioNTech, Moderna or AstraZeneca vaccines "are still protective. You are still less likely to get infected - but if you do, you will have similar levels of virus as someone who hasn''t been vaccinated at all." The data used for the study do not show how likely it is that a fully vaccinated person with the Delta variant can pass on the infection to another individual, compared to an unvaccinated individual with the virus. But the high viral loads found in the study are a strong indicator that the risks of transmission from both vaccinated and unvaccinated people with the Delta variant could be similar. https://news.yahoo.com/study-vaccines-dont-lower-viral-100625606.html
以色列最新实地报道,假以时日,防重症也是镜花水月: What is clear is that “breakthrough” cases are not the rare events the term implies. As of 15 August, 514 Israelis were hospitalized with severe or critical COVID-19, a 31% increase from just 4 days earlier. Of the 514, 59% were fully vaccinated. Of the vaccinated, 87% were 60 or older. “There are so many breakthrough infections that they dominate and most of the hospitalized patients are actually vaccinated,” says Uri Shalit, a bioinformatician at the Israel Institute of Technology (Technion) who has consulted on COVID-19 for the government. “One of the big stories from Israel [is]: ‘Vaccines work, but not well enough.’”

Preprint from a Lancet journal on delta breakthrough cases. Breakthrough cases 带毒时间是8-33天,median21天,你觉得短么? https://papers.ssrn.com/sol3/papers.cfm?abstract_id=3897733 Copied from the abstract: "Viral loads of breakthrough Delta variant infection cases were 251 times higher than those of cases infected with old strains detected between March-April 2020. Time from diagnosis to PCR negative was 8–33 days (median: 21)." "Interpretation: Breakthrough Delta variant infections are associated with high viral loads, prolonged PCR positivity, and low levels of vaccine-induced neutralizing antibodies, explaining the transmission between the vaccinated people. Physical distancing measures remain critical to reduce SARS-CoV-2 Delta variant transmission."
You are still less likely to get infected - but if you do, you will have similar levels of virus as someone who hasn''t been vaccinated at all." 我看这段的意思也是打了疫苗更不容易被感染上,但是如果被传染上,会有类似水平的病毒量。这可不是显然吗,都已经被传染发病了,疫苗又不是抗体。疫苗只是减少了被感染的几率。 我看也是有意思,各种说法来证明疫苗不好,之前是睿大妈转打了疫苗感染更高,现在是打了疫苗传染性一样

老人是以色列最早完成2针的群体,体内抗体浓度下降,达到可以发生ADE的抗体程度了,所以要打boost
这就是这个疫苗的问题 终身依赖
和流感疫苗一样,基本就剩生意了
这不是秃子头上的虱子吗?我儿子去年底上课的时候,他们生物老师就这么说的呀!要你现在当大新闻普大喜奔?
现在证明保护不了,其实打了疫苗染病更容易无症状到处浪不隔离,反而传染更多人 能防传染的还是口罩,口罩应该mandate,疫苗既然不防传染,副作用又这么多,还是归个人选择吧
什么叫“达到可以发生ADE抗体程度了”,是说抗体下降比完全不打疫苗更糟糕吗?另外不是说新冠不会有ADE吗?有懂的妹子来科普一下吗
ADE是在抗体浓度低的时候发生的
比如革登热,打疫苗出现ADE不是马上的,是很长一段时间之后才发生的
这也是为啥疫苗实验需要比较长时间的原因,冠状病毒是ADE现象最多的病毒
那国内全民灭活的岂不是打完一个月就衰减到这个level了?
这种只定性, 不定量的标题, 是用来忽悠谁的?
这个不是严格的viral load,还是用的ct,国内最近把广州那波做了同样的分析,ct值前五天确实差别不大,但是实际viral load打了疫苗还是好不少。当然你要是说相信灭活是这样的我只能送你两个字了
另外就算是ct值,新加坡做过类似研究发现打了疫苗5天开始还是有非常大的区别,有人说是细胞免疫需要时间激发
打了疫苗可以保护自己,戴了口罩可以保护别人。
这不挺好的,如果每个人两样都做好,这个瘟疫也不会搞成这样。
打了疫苗的人感染病毒后,病毒仍然会在鼻腔等黏膜复制,会成为长期无症状带毒者,不但会传染他人, 自身免疫igG一旦下降,自己也会发病
你这就是扯淡了,要这样国内早把南京打了疫苗感染的人终身隔离了
减轻病重程度,还真没有什么双盲实验,知道的说一声,这更多是“理论共识”吧,提前准备抗体,抵抗力当然强,但对delta有多少作用,也不清楚
文章呢?证据呢?
疫苗防重症与死亡,这个基本已经是所有学界医学界公认的了。
不会最后就是生意吧? 所以口罩一定要脱, 疫苗一定要打?
看到这个一惊,这得时不时补?
戴口罩保护他人 打疫苗防止重症以防医疗资源挤兑 两个都要 并不需要二选一
你这说的。。。难道口罩一定要戴,疫苗一定不打就不是生意了?生意不生意的,能够帮助缓解疫情就是好事,更何况mRNA疫苗大多数是在美国境内生产的,跟着分一杯羹的企业其实一点都不少。当然如果你在中国的话,就另当别论了
感染后发作了的免疫系统启动,病毒就被消灭了。
无症状的免疫系统并未启动,或者未全启动,病毒消灭的慢
我们当初打的时候怎么不告诉需要booster? 现在打完了才告诉我们要一直打下去。
带口罩即可保护他人,也是自我最有效的防护手段
当初打的时候又没有delta的数据 你这个要求也太不合理了 你不打疫苗怎么下去? 你愿意躲在家里一辈子 也可以啊 美国能有最有效的mRNA 疫苗随便打 已经很幸福了, 好多国家想打还没有呢 病毒又不是美国制造的 你有怒气去质问病毒产生国啊
疫苗能防多少%“得新冠”也是众说纷纭,从95%到40%,而且可以无症状传染已经是定论,所以并不是打了疫苗没症状的(被认为没被“传染”)就不会传染他人了
一直有人说不打疫苗就是不保护不能打疫苗的儿童。
什么叫做终身隔离?
你流感疫苗打一次管一辈子了?

看看我总结的 real world 数据:康州的Covid数据证明疫苗保护率很好 https://forums.huaren.us/showtopic.html?topicid=2720239&fid=398
说说疫苗在现实中的例子吧。我们一位朋友在covid病房, 现在的病人, 几乎都是没有打过疫苗的, 只有一例是刚刚结束化疗的打过疫苗病例
觉得CDC应该给这类统计数据,医院里病人有多少%打过疫苗的,多少没有,每天更新,这很容易,为什么不做 美国各种奇葩操作,主要是医疗有利益,屁股太歪,结果反而失去credibility,现在更相信欧洲以色列的study和数据
你自己去医院看看或者打听一下不就得了?楼上说是医生朋友所见,你不还是不信吗?周围总有在医院工作的人吧?
感觉也没多久啊。这么折腾的话,一年就得2针?
这种打听不就是道听途说盲人摸象,恰巧一个地区的医院重症的打过疫苗比不打疫苗的多或者反过来,难道就可以推测出全美的情况了?怎么还会有受过大学教育的这种思维??
现在这种形势,CDC怎么就不该给出官方统计数据了?整天给混乱的CDC洗地,我发现一些皈依狂热者早就失去了最起码的理性思维
你这么小心,还去餐馆吃饭?
你别在这里带节奏了 95% 是原始毒株 40% 是六个月左右针对delta 这些数据都是实打实的研究 谁给你众说纷纭, 所有数据都说明打疫苗很有用, 应该都打。 反而你家土工的疫苗啥数据都没有 全靠编 你还是替土工担心一下吧 要封锁到那一年啊
现在没有数据支持 ade,以后有没有不知道,先不要自己吓自己!
明明有 CDC也统计住院的break through case 你自己和总的比较一下不就行了吗 你搜集疫苗无效的小道消息这么上心 还能篡改文章的本意 现在装傻没有数据了 别在这里装了 有任务不希望美国都打疫苗就直说了
她不是看不懂 是有意的 你看看她其他的帖子就知道了 华人上几个ID 每天恐吓疫苗有害无用 其实可以举报FBI 的 他们要是有土工背景的话FBI可能会有兴趣查下去的
是的,早不跟他们争了,别人都是带节奏,只有他们是science,lol,他们愿咋咋,打成刺猬也是他们的自由~
You are still less likely to get infected - but if you do, you will have similar levels of virus as someone who hasn''t been vaccinated at all."
我看这段的意思也是打了疫苗更不容易被感染上,但是如果被传染上,会有类似水平的病毒量。这可不是显然吗,都已经被传染发病了,疫苗又不是抗体。疫苗只是减少了被感染的几率。
我看也是有意思,各种说法来证明疫苗不好,之前是睿大妈转打了疫苗感染更高,现在是打了疫苗传染性一样
我希望他们言行一致,能够坚持自己一直不打疫苗,不要反了半天最后又打疫苗了,跟本版某位似的,但是最起码那位还坦率承认。这几位天天反疫苗的回头自己蔫不出溜儿偷偷打了,那就没劲了
你有更好的选择吗?
我什么时候说疫苗不好啦,首帖也说了,疫苗可以保护自己,减轻病重程度
这里谈的是,打了疫苗的人,传染他人的能力,而这个能力是直接和其带病毒量决定的,现在发现,打不打疫苗,病毒量类似,所以文章推论他们传染他人的能力类似,这也不是我说的,是文章说的,也很合逻辑
至于有人说打了疫苗的人“得病”少,所以传染他人少?我前面也回应了,打了疫苗的更不容易出症状(疫苗的好处),但并不等于他们不带病毒,无症状可传染早就是定论
打了疫苗被病毒感染但没症状的人在上呼吸道的viral load有多高目前是个unknown。 这个research没法做。因为breakthrough的人可以知道此人肯定接触病毒了。但是那些打了疫苗受感染没breakthrough的人毫无症状没法identify。大街上随便拉打个打过疫苗的人,测上呼吸道的viral load没有意义。因为如果zero的话,可能根本就完全没被感染过,而并不能归结为疫苗suppress了viral load。 所以说打了疫苗感染病毒但没breakthrough的人,上呼吸道的viral load量到底是多少全靠脑补。 不过真有可能在上呼吸道打没打疫苗区别不大。因为那块的生理结构导致即便有抗体,量也不咋地。只有病毒travel到deep lung才会受到有效阻击
我觉得她就是没看懂。
我还是希望他们去打疫苗,哪怕实际打了,嘴上还不承认。
认为口罩和疫苗mutually exclusive,或者说用口罩来反疫苗的人应该有两种可能,一种是纯粹反疫苗,一种是没怎么用过口罩的.大家自行对号入座吧.
➕1
成人疫苗率达到7%%以上就可以保护小孩子了。 纽约私校规定12岁以上开学前必须两针打完20天以上。
这和我观点是一致的啊,就是打了疫苗,无论有没有“得病”(show症状),传染他人的能力并没减少
对啊这个道理竟然很多人不知道! 只保护其他人这个说法竟然!那么多人认为是对的! 生气
是的 搞得我有点shocked 心里很排斥 想到以后担心这个不能出去堂吃打击太大了
cdc是这个世界上对新冠最无知的一个存在,天天跟在新闻后面跑。。
Mm厉害👍
这俩没区别,都是政治挂帅
看到这个就想起CDC的口罩令 真的是害人!
这位楼主确实特别执着😂
呃。。。你反疫苗的立场大家都有目共睹吧?
她自己猜的
只要你传染了保证不去医院。你别管人家就行,天天发些自己都看不懂的新闻justify 自己的行为。
就当打疫苗是提前吃药了……
晕 抗体降到什么程度容易发生ADE?
这是传染病,谁都不可能独善其身。
是啊,口罩太有用了
你说呢? 你是在墙里看不到新闻吗? 你不知道原始毒株和delta 的区别吗? 别装傻了 土工都不敢提对delta的有效率了。 你自己泰国在美领馆门口要求辉瑞打医护 在中国使馆门口横幅不要科兴了嘛?赶快回去发动粉红反泰国吧 又辱华了
总之就是放不了delta了呗
