Approximately three quarters (346; 74%) of cases occurred in fully vaccinated persons (those who had completed a 2-dose course of mRNA vaccine [Pfizer-BioNTech or Moderna] or had received a single dose of Janssen [Johnson & Johnson] vaccine ≥14 days before exposure).

结论是: 打疫苗也不能不带口罩浪 Jurisdictions might consider expanded prevention strategies, including universal masking in indoor public settings, particularly for large public gatherings that include travelers from many areas with differing levels of SARS-CoV-2 transmission.

Jerusalem (CNN) Israel's Prime Minister has announced a program to roll out a third dose of the coronavirus vaccine to people over the age of 60, becoming one of the first countries in the world to make such a move. People over 60 will need to show they received their second dose of the vaccine at least five months ago.
Several studies, including ones referenced in the C.D.C.’s presentation, have shown that vaccines remain effective against the Delta variant, particularly against hospitalization and death. That has held true in the real world: About 97 percent of those recently hospitalized by the virus were unvaccinated, the C.D.C. said. But in counties where vaccination rates are low, cases are rising fast, and deaths are also on the rise.

CDC also said: No mask needed; Mask mandatory; No mask for vaccinated; Mask regardless of vaccination status. The list can go on.

这疫苗最大的作用是防重症了？前几天新闻说几个月后疫苗有效性大幅降低，所以需要每半年打一次吗...... 如此看来是不是没完没了了，频繁打疫苗也不行吧，研发速度未必跟得上变异速度(可能同时几种变异毒株...)，最好的办法是不是还是全国自觉居家隔离一阵，所以绕了一大圈最后可能还是得用最原始的方式？

事情很难说的，预测未来的人，都会失败的很惨。现在只能做最坏的准备and hope for the best.
你难道真以为covid病毒会绝迹？冠状病毒进化快，以后就是流感的一部分。每年打疫苗是正事。潘多拉的盒子打开了，就再也回不去了。
对防传染的有效率很重要吧 否则全世界一直互相传染，然后病毒一直变种，继续传染，啥时候能恢复正常生活
那么重症率呢，死亡率呢？疫苗有效率不看这两个数据啦？
你说得没错，样本稀少，得不出有三位有效数字的有效率，不过可以得出的结论就是有效率很大几率<50%和以色列的数据一样。
🛋️ 沙发板凳
你是奴才出身吧，张口就主子主子的 cdc今天发的数据，你不识字还是眼睛有问题 难道cdc发布的东西还不能说了
如果全部打过疫苗后，那得病的肯定100%的打过疫苗啊，那应该看的病的和没得病的比例，光看这几个得病的有什用啊
RE
随着接种的人口比例增加，接种的感染比例当然也会增加。
数学！
别人有没有主子看不出来，你有主子却是秃子头上的虱子－明摆的事嘛。谁看个CDC消息就能得出美国要完的结论啊？哈哈哈，不好意思，你太心急了。
果然。看见自己露了马脚，赶紧改帖子。
这架势，不来一针booster算你没打过
Barnstable County 是富州里的富县， 大兰州里的纯白县。 这种地方的接种率一定极高。
美国接近49.3%的人口完全接种疫苗，57.2%接种一针，仍然每天新增几万，最近更是八九万，你还想要啥数据
一个破口罩，开始死活说不需要带，好不容易带上了，又开始让拿下.

只有一半人完全接种，再加上 Delta 的强烈传染性，你觉得会全部归零？？？
俺说的是数据，不是奇迹！！！
什么时候说归零了？另外零和八九万一个概念？ 按照你这种逻辑，什么数据也满足不了你，另外，需要数据请自己手动查 随意吧，就是分享下最新的新闻，自行判断吧
看来vaccine passport势在必行。
隔壁贴看到口黑心毒， 你拿着送给那个人吧
这个在美国不难实施，但是中国就不行了。毕竟翠平到现在一事无成，一定要搞一个0感染来彰显自己的功绩
这该怎么理解，从统计上。69%的居民接种了疫苗。74%的中招的是打过疫苗的。五人住院，四人打过疫苗。 那case总数有下降吗？比起没打疫苗前？
Barnstable County 打过两针的今天 64% 不到，打过一针的73%不到。能推出什么结论？
那位所谓的教授，还整天说自己多少人点赞，洋洋得意。 你快出来走两步，看看给你点赞的人的智商吧，哈哈
这些都看不出来，只能大概看出形式不容乐观
case总数现在不是爆了吗，你可以把麻省最近的跟去年同期的比比
结论是: 打疫苗也不能不带口罩浪

每个帖都会看到这种高赞扯淡回帖。接种率数字网上都能查，但偏偏要莫名其妙的假设个100%出来。
是啊 都疯癫了
不会，病毒不会与人类长期共存，明年完成任务他们就会离开，这里会清零。但不是所有人都能看到，接下来的目标是青壮年和上班族
绝对不乐观 疫苗根本没啥用 白受罪
说打了就不戴口罩的那些真的有罪
呵呵，mm还好吧，什么时候打第二针
看这次受罪程度多猛了……
逼迫整个社会做一件未必安全的事 也是活久见
我在股票群也看到了
当时不是说打了就可以不带嘛。。。。现在又慌忙改回去了
有啥办法中国人命值钱。躺平死几十万相比自由也没什么，不要死到自己就好了。
我看了每个州的本月数据，几乎没有几个例外都是国庆前后几天感染数目开始大幅攀升的，但是死亡数字大体稳中有升，所以国庆是个折点，大家完全放松了。
所以马萨诸塞这个county的疫苗注射率是88.1%。 如果疫苗保护率是95%，那这个county的疫苗注射率应该是93.7%
有谁可以fact check一下这个county的注射率是不是这样？
不对吧，应该是 0.1x/(1-x)=0.74/0.26
刚刚查了一下，这个镇官方的接种率是114%。。。。因为在这里打疫苗的不一定是本地人
https://www.masslive.com/capecod/2021/07/how-provincetown-achieved-a-114-vaccination-rate.html
这tm是什么统计方式。 那之前说的，富人区接种率高，是不是也可能是因为接种站点更多设在富人区？所以穷人区的人都到富人区打疫苗。
这里面说的都是Massachusetts residents
我猜都不带，裸着鼻孔逛
非 delta 防传染，当然不要解释成 100% 。
6、28-7、27: 1157 感染是fully vaxxed （7 hospitalized 3 death), 10234是unvaxxed (236 hospitalized 3 death. 这个county 70% eligible population for vax has been fully vaxxed
https://www.sandiegocounty.gov/content/dam/sdc/hhsa/programs/phs/Epidemiology/COVID-19%20Case%20Summary%20by%20Vaccination%20Status.pdf
回错
现在说只防死亡了 连住院都不防了
那是现在病毒给的假象，等到1月，你会看到完全相反的现象
只有4个住院的而且都是pre condition。近期不回国不需要双阴检测的，根本都不是个事
google说这个barnstable county女的不男的多啊
没变啊。。。疫苗打的人越多，感染的人里面打过疫苗就会越高啊。极端的例子就如上面有人说的，全部人打过疫苗以后，那么不管有几个人感染也是100%打过疫苗的了啊。何况的确疫苗在对付delta variant效果的确减弱了一些，但是还是很不错的。
因为没接种过的也都出来浪了。
重症率和死亡率的变化更说明问题
你把100个打过疫苗的人关一起再放点病毒，出来看看被感染的是不是100%打过疫苗的？
vaccination coverage among eligible Massachusetts residents was 69%
不是100%
就算80%的成年人打了疫苗，74%感染的是打过疫苗的=疫苗几乎无效。
问题麻州接种率不是100%啊，只有70%。
只要74%接近接种率，疫苗就是几乎无效。
如果不是74%，而是20%感染的是打过疫苗的，哪疫苗就有效了。
那要看出来浪的里面有多少比例是打过疫苗的才行。
有人打疫苗然后出来浪，有人不打疫苗戴口罩也不出来浪。那凭什么打疫苗浪的人指责不打疫苗戴口罩又不浪的人？只是方法上的差异，实际的结果说不定后者更好。
没完没了的烦死了。 该咋咋，照吃照喝，我也没见周围大家都倒地不起，遍地死尸。
说的对，还记得之前有人抱怨打疫苗就是为了不戴口罩出去浪，现在这趋势是各方面防护都要做好才是保护好自己的最佳方式
哦，你就是那位退党保平安的nickname。
CDC还活着啊。早就不听它叨叨，疫苗口罩少出门，三宝保命，不能靠 CDC。
我们这边好像只有70%的人打了第1针或者一针以上。
开始的时候是说防自己感染，防传播病毒给他人. 所以为了保护别人，更应该打, 这我记得很清楚。
因为此事，和同事conference的时候还有过争论，我提醒他们，根据ＲＮＡ病毒的特性打了疫苗也不见得就阻断感染，或者防止携带病毒pass on给别人， 不能因为打了疫苗就无所顾忌。他们觉得我被misinformed, 疫苗就是为这两样设计的。 当时没有更多数据支持，最后我们组的头信誓旦旦一锤定音说打了疫苗，传播病毒的可能性下降９０％， 他看了某paper，period,所以大家都该去尽早打。
我们这个小公司的ceo前两天还全员发信说打疫苗保护自己、保护community呢
如果不防传播，白等为啥还拼了命的推疫苗
合理的问题， 没有人知道答案
我看Twitter上有当地人说这个super spreading event是所谓的bear week，搜了一下啥叫bear week，相当的辣眼睛，怪不得能弄出这么多breakthrough case来
欧美文明的前进方向
有数据也不给我们看
大家看看上面三篇文章合在一起什么意思： 第一疫苗不减少的病的几率， 麻省74%得新冠的人是打了疫苗的。 第二打了疫苗的人Viral Load不比没打疫苗的少， 非说打疫苗的人是保护了别人的人可以休息了。 第三在打疫苗的了新冠的5000多个人里有329个重症住院的，80人死亡， 所以疫苗也不减少重症。 这疫苗除了打出个副作用以外还干了什么？
CDC also said: No mask needed; Mask mandatory; No mask for vaccinated; Mask regardless of vaccination status. The list can go on.
还有人看不清， 大家都是实验室小白鼠。
stop following CDC 和电视新闻, 用自己的common sense。 觉得需要带口罩的继续带口罩。增强免疫的VC, VD,槲皮素＋锌片吃起来，学习一下洗鼻，清理nasal airway 的病毒。相信印度南美经验的屯点硫酸羟氯喹， 阿奇霉素和伊维菌素。 不信的，注意观察，有症状积极早期治疗，不要拖。
非必要少去近距离密切接触的地方，比如酒吧人挨人跳舞，和不同的人频繁夜生活。其他一般的自驾旅游，下餐馆， 住旅馆都没什么，恢复正常生活， 该上班上班， 该上学上学。惶惶不可终日，不敢出门，导致免疫下降， 才是得不偿失。
这么说那些打了疫苗的科学捍卫者情何以堪？他们捍卫是哪门子科学？也就是有点牺牲精神，无脑勇当实验的小白鼠罢了。
你看看97%这个数是从哪天开始算得。
智商有问题。
那不简单，做个数学呗…每天新增多少vaccinated VS unvaccinated除以打过疫苗population和没打过的population呗。 现在打过疫苗的人数有50%了吗？有的话就不用除了。就看新增人数比好了。
请专业的解释一下FIG2的意思。
re
赞同，这才是正确的态度
麻省那个例子不能只看分子， 不看分母。
如果是打了疫苗的75%都感染了才能说明疫苗对变种基本没有抵抗力。75%的感染者都打了疫苗只能说明打疫苗不能100% 防感染。
如果人群中100%打了疫苗，那就是100%感染者都打了疫苗。疫苗没有用不是这么表达的。比如1000个人，900个打了疫苗，100个没打。总共100个人感染了，75个打了疫苗，25个没打。打疫苗的感染率是75/900=8.3%， 没打疫苗的感染率是25/100=25%。 8.3% VS 25%， 能说明疫苗基本没有用吗？
你这算法也不科学，例子里的接种率严重影响最后的结果 比如那个小镇大概20万人，10万打了疫苗，10万没打。总共500个感染，其中75%（375）打了疫苗，125个没打。打疫苗的感染率是375/100,000=0.375%， 没打疫苗的感染率是125//100,000=0.125%，这么看是不是打了疫苗的反而更容易感染？ 实际上目前全美完全接种率大概50%，而7月时那个小镇的接种率不太可能是90%
大家的心都清楚得很。
90%打了疫苗。。。。。哪里来的自信哦，你以为是中国吗？
