这例子举得也太离奇了

动不动就否定有用吗？

WASHINGTON (AFP) - The Pfizer and Moderna Covid-19 vaccines should remain highly effective against two coronavirus variants first identified in India, according to new research carried out by US scientists.

The lab-based study was carried out by the NYU Grossman School of Medicine and NYU Langone Center and is considered preliminary because it has not yet been published in a peer-reviewed journal.

"What we found is that the vaccine's antibodies are a little bit weaker against the variants, but not enough that we think it would have much of an effect on the protective ability of the vaccines," senior author Nathaniel "Ned" Landau told AFP on Monday (May 17).

The researchers first took blood from people who were vaccinated with either of the two shots, which are predominant in the United States and have been given to more than 150 million Americans.

They then exposed these samples in a lab to engineered pseudovirus particles that contained mutations in the "spike" region of the coronavirus, which were particular to either the B1617 or B1618 variants, first found in India.

Finally, that mixture was exposed to lab-grown cells, to see how many would become infected.

Finally, that mixture was exposed to lab-grown cells, to see how many would become infected.

The coronavirus is known to latch on to a particular receptor on human cells called ACE2, which it uses to force its entry.

Landau's team showed the Indian variants were able to bind more tightly to this receptor, like other variants of concern. This might be linked to its increased transmissibility compared to the original strain.

"Our results lend confidence that current vaccines will provide protection against variants identified to date," the team concluded.

However, they do not preclude the possibility that newer variants that are more resistant to vaccines will emerge - highlighting the importance of widespread vaccination at the global level.

新加坡政府有钱有能力，应该自己试验，样本小也没关系，关键是更加贴近实际。
而且要多用几种疫苗，try and error。
这件事去年就应该干了。

没有peer review急吼吼的发出来是不是早了点

没当论文看还行！

科技进步了那么多年，还是被个病毒折腾得欲仙欲死，整出来的疫苗都不知道有没有用。

再也不信专家了。都是吹牛皮的。

有啥qub

靠伟大的制药，疫苗设备等公司。
互联网公司没办法救命了，最多通过技术帮要救命的人发送消息。

我看最后还是得靠土法：强制隔离。

中国新加坡这种上面说下面老实听的，靠隔离可能还顶得住。

新加坡要是疫苗打了个百分之七八十也就没这么慌了。听说最近疫苗紧张，有批准科兴的压力。没批大概是想等WHO批先。

（早报讯）印度一项研究指，阿斯利康疫苗对抗B1617变异毒株的有效率超过97%。

新德里的因德拉普拉斯塔阿波罗医院此前对3235名已接种阿斯利康疫苗的印度医护人员进行研究。结果显示只有85名医护人员接种疫苗后仍确诊冠病，而住院率仅为0.06%。

医院医学总监西巴尔指出，研究表明疫苗对抗B1617变异毒株的有效率达97.38%，指变异病毒突破疫苗导致感染仅属极少数情况。

西巴尔更表示研究中没有患者需到深切治疗部留医或死亡，强调阿斯利康疫苗十分有效，接种者即使染疫也只会出现轻微症状。

应该大面积撒网疫苗，在新加坡土地上找人试验。
也许疫苗到了新加坡也不灵了。
只有自己试验才知道。
找各种外劳试验，给点好处不可能找不到足够愿意当小白鼠的。

直接贴paper的链接啊。

这叫不见棺材不落泪。

这就是个研究的update吧，没到发paper的程度b

除非自己被病毒搞惨了，不然该示威抗议的还是会去。
要是严重的不可收拾出动军队戒严，估计整个国家缓过来要好几年。
要是那样习大大开心死了。立马两岸统一。

美国zhiqian最多的时候一天死了5000多人好像，人家可谈定了
