(引用 hongmeng:来来来，懂科研的熊猫来秀一下你的知道面有多广动不动就否定有用吗？)目测是纽约大学医学院的结论https://www.straitstimes.com/world/united-states/pfizer-moderna-vaccines-effective-against-indian-coronavirus-variants-study
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.[hongmeng (5-18 17:47, Long ago)]

在美国有用不见得在新加坡有用，比如气候，人种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。

关键时刻还要靠实体技术靠伟大的制药，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。

研究：阿斯利康疫苗对抗B1617变异毒株有效率超过97%（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。

要真是这样，新加坡没阿斯利康咋办？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。

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。
