疫苗可能只防止重症，而不防止感染，德国一个养老院17人感染，其中14人1月份就打了疫苗。

You were vaccinated months ago: 14 residents and carers of a nursing home tested positive for Corona

As it is, an outbreak in Germany has turned into a real-world acid test for COVID-19 vaccines.
就是说因为有一个人感染所以给其他人做测试，才发现17个感染的，其中14个full-vaccined. 要是不做测试可能都不知道有感染的。

What the outbreak appears to show is that coronavirus vaccines do not necessarily stop a person becoming infected with COVID-19, but that they do prevent the most severe symptoms. Germany's vaccine authority, the Robert Koch Institute, says that would be true for the Pfizer-BioNTech vaccine in about 95% of cases.

COVID vaccines tested on real-world variants in Israel

The bizarre: 14 of the residents and carers who tested positive have been fully vaccinated since January. Previously, it was assumed that vaccinated people would be far less contagious after infection.

At time of writing, those who had tested positive for the virus reported mild symptoms or no symptoms at all.
无症状感染，说明没有防止传染，只不过没有症状吧了。以前三期实验没有检查无症状感染。

看来目前疫苗只是预防重症或者疫苗只有3个月有效性 （1月份接种的）。大家对疫苗的期望太高了，打了疫苗也不能放松，特别是有家庭其他成员没有打疫苗的。

这个要是中国疫苗，不是笑翻天了。

为什么要笑翻天 中国疫苗不是官方说有效率50.7%吗

这可不是新闻，我就贴过不止5次了，2月以色列的对比试验显示602000打过2针的人中，608人感染，大于千分之一，其中21人住院，7人重症，都有基础病。

而且608人测试感染，35%是因为有症状，65%是因为与感染人有过密切接触。所以如果普测，实际感染人数会更高。

对比试验表明，比未接种对照组95%的感染保护率。

Maccabi looked at data from about 602,000 of its members who were at least one week past their second dose of the vaccine. Among them, 7 were hospitalized with severe symptoms, 3 with moderate symptoms, and 11 with mild symptoms.

All of the hospitalized members were over age 50, and half of them had a chronic health condition, such as morbid obesity, according to Ido Hadari, a Maccabi spokesman.

Among the 602,000 vaccinated members, tests showed that 608 became infected with COVID-19. Maccabi did not routinely test members, but of the 608, 35% chose to get tested because they had symptoms of COVID-19 and 65% chose to get tested because they had been exposed to someone with the virus.

Pfizer vaccine is about 95% effective against COVID-19, Israeli data shows

Data from more than 600,000 vaccinated Israelis show the Pfizer vaccine is 95% effective, with only 21 vaccinated people ending up in the hospital with COVID-19.

以色列跟这个根本不是一回事。德国这个是同一个养老院14个人感染。这个如果按照有效率计算可能百分之十都不到，而以色列的符合二期临床实验的结果，感染人数608跟总接种数有关

前几天中国西安一个医生打了疫苗感染，这里很多人笑，你没有笑？这个可是同一个养老院14个人感染

德国这养老院突破的比例是够高了，会不会以前就有感染，没有测出？美国那个大数据比例比以色列的低多了，5800/77million.

与周围的病毒密度有关。
养老院里相对封闭，一旦有人感染，很容易扩散到其他人。

有人笑中国是因为不相信中国几乎0感染，谁知这位医生接触到了哪位感染者。

有些人即使隔离了14天还是传染别人。
这个医生可能接触了类似的人。


这里是最新的例子。

疫苗的作用是两方面的，一是减低感染，一是减低重症。
能避免感染当然好，即使感染了，能避免重症同样重要。

有人对比美国的三种疫苗，强生的防感染率不如另外两个品种，但三种疫苗减低重症的作用都是100%，至少报道是这样说的
打了疫苗即使感染了，无症状或只是个（重）感冒，也算是有效了吧。

 

[向问天]

但三种疫苗减低重症的作用都是100%，

这个肯定不是。
美国有很多人接种后再感染死亡的。

这个德国情况特别有意义，对于那些打了疫苗的，可能生活也回不去过去，不能随便浪，特别是家里还有其他成员没有打疫苗的，接种的人可能避免重症，但是带病毒回家也不行

 

[lindamy]

各种疫苗如果能起到减轻症状，增加抗体，就算很成功有效。

 

[RareEarth]

实际上接触病毒都会感染。所谓不会感染，只是感染之后，在体内病毒浓度达到检测水平前，就被身体免疫机制自行克服了

如果身体免疫机制不够强，就可能出现症状。如果能防止重症死亡，最大的目的就达到了。

这种情况下还是有可能传染他人。所以即便都打过疫苗，降低了重症率和死亡率，口罩等隔离病毒的措施仍然是必要的
