「群体免疫」莫斯科副市长:20%居民已有抗体 \⊙△⊙_

群免进度上,要问谁能胜过莫斯科,估计得看武汉。

来自莫斯科的消息
One in five healthy Moscow residents has coronavirus antibodies, suggesting they have been infected and could be immune for a period of time, the Russian capital’s deputy mayor said Friday.

Anastasia Rakova said that more than 90,000 Muscovites had been tested from June 5-18 as part of the citywide testing program’s third stage.

“We can say that herd immunity continues to form and about 20% of Muscovites currently have such immunity,” Rakova said.

She noted a 2.5% increase in the presence of antibodies from the city's previous studies.

City officials say they plan to test 6 million people, or around half of Moscow’s total population, for antibodies.

National health officials said earlier in June that one in seven Russians, or around 14%, tested for Covid-19 have developed immunity to the virus. The percentage of immune cases among minors under 17 years old totaled almost 20%.

Moscow’s mayor has previously suggested that up to 2.5% of the city’s residents, or nearly 300,000 people, may have been infected with Covid-19.

A recent study conducted in China has said that the antibodies may fade within two months of infection and suggested that asymptomatic people have weaker immune responses to infection.

Experts also warn that the presence of antibodies doesn't necessarily confer total immunity to the coronavirus.

Russia has confirmed more than 620,000 coronavirus infections as of Friday, the world’s third-highest caseload. Moscow, which accounts for more than one-third of Russia's cases, began to gradually emerge from lockdown this month.

Almost 8,800 people have died nationwide, the lowest death toll among countries with similarly high numbers of Covid-19 cases.


没什么复杂内容,所以只挑重点来说。

-----------------------------------------------
6月26日,莫斯科副市长Anastasia Rakova说,从6月5日到6月18日对90000居民做了测试,结果显示五分之一的人有抗体。

按照她的说法:群体免疫正在继续形成,20%的人有了免疫力

而据6月10日的报道,这一数字是七分之一,即大约14%。

先假设这是真的,那么我们可以放心期待三个星期后,莫斯科将有三分之一的人免疫(认真脸

------------------------------------------------
这种“群体免疫”数字,拿出来的目的当然首先是安定人心,让大家放心复工。

目前,全世界的统计数字显示死亡率是5%。重症率不超过20%,就算这些人全死了,对独裁者而言只是解脱许多负担。所以不难理解,为什么一天新增7000例,普京也照样要解封,要阅兵,要复工。

但是,群体免疫不等于没有免疫力的人免疫,比如普京。所以他仅有的安全选项还是疫苗。

拖时间,估计不止是普京,也是习近平的心思,当然还有几乎全部地球人。

但我只能说声对不起,冷水来了。

这一报道中引用了一份“中国的研究”,说抗体(免疫)的持续时间大约是2个月,而无症状的感染者,其形成的免疫能力也比较弱。

虽然中国的一切都要打问号,但这2个月的时间,和一季有效的流感疫苗相差不远,有参考的意义。

所以,还是早就说过的,但很多人想忽略的那句话:不要指望疫苗,指望不上的。至于免疫有效期是不是那么短,我倾向于相信西班牙流感的历史经验。

福奇也才说了一句“可能要几十年”
疫苗最快年底前就可供使用,但是他说,研制出安全有效的疫苗并不容易。证明疫苗安全有效有时候需要几十年时间。


这表明了专家没有把握拿得出疫苗。严峻,但那是现实。

最安全的做法,是从现在开始做好被感染的准备。无视的这一现实的,今年秋冬恐收获意外

------------------------------------------------
现在感觉更强烈了:第一个说出群体免疫的,真的是勇士。
