Washington Post has an article on this topic based on Israel data. And the answer is YES. It's a long article that worth reading. Here are some paragraphs and data. https://www.washingtonpost.com/outlook/2021/08/31/covid-israel-hospitalization-rates-simpsons-paradox/ Something very similar is happening in Israel. Vaccinated Israelis, like White Americans, are older as a group than unvaccinated Israelis. And that’s why they’re going to the hospital at a rate higher than you might naively hope. Among Israeli adults under 50, as of Aug. 15, 3.5 million were vaccinated and 1.1 million were not. That’s still a considerable number of vaccine holdouts. Among those 3.5 million vaccinated younger people, just 11 were hospitalized — about three per million. Meanwhile, of the unvaccinated in this age range, 43 were in the hospital, or 39 per million. Note that hospitalizations of young people for both the vaccinated and unvaccinated are low, because younger people rarely suffer the severest illness from covid-19. Still, vaccination reduced the rate of hospitalization more than 10-fold in the population under 50. Now look at the population 50 and older. There are 2.1 million vaccinated Israelis over 50, and 290 were in the hospital Aug. 15. That’s 136 per million, a rate that dwarfs anything younger people are experiencing. And unvaccinated older Israelis? There are very few people in that category: just 186,000. But of that group, 171 were hospitalized — a grievously higher rate of 919 per million.In the older population, vaccinated people were less than one-sixth as likely to be hospitalized as the unvaccinated.
“CNN”报导，截至8月30日，美国疾病控制与预防中心（CDC）已收到1万2908例完整接种疫苗后仍染疫住院或死亡的报告。同时全美有超过1.73亿人已完整接种疫苗，意味著突破性感染的机率“不到13000分之1”。CDC数据显示，大约70%导致住院的、以及约87%导致死亡的突破性感染发生在65岁及以上的成年人中。根据研究，美国未接种疫苗的成年人因感染新冠住院的可能性是完全接种疫苗的成年人的17倍，此外，因突破性感染住院的患者往往年龄较大，并且更有可能至少患有3种潜在慢性病。
研究还发现，因突破性感染被送入医院且接种疫苗的成年人中，年龄中位数为73岁，约71%的人患有包括糖尿病、心脏病、自体免疫疾病等。未接种疫苗的新冠住院患者年龄中位数则是59岁，约56%罹患3种以上慢性病。
自6月底至7月底，Delta病毒株占所有确诊患者至少半数期间，未接种疫苗成人住院的机率是完全接种疫苗成年人的10倍。整体而言，由于Delta病毒株成为疫情主流，因此所有年龄层中未接种疫苗的成年人住院风险都更高，但50岁以下成人的风险差距特别大。
不过由于美国CDC的数据是基于各州的“自愿通报”，因此可能尚不完整，但多项研究仍表明类似趋势。
不过估计这些人里面90%的都打了疫苗，没有对照组了。
经济不行了
“突破性感染”之前就是按照重症和死亡的人数算的么？？我一直以为是按照感染人数算。还是CDC又重新定义了？
long covid 是 副作用吗？
我周围知道得过的，就有一个 还未完全恢复，是个医生，其它的，包括进过ICU 都已经完全恢复，那个医生也在慢慢好转，但上个月听说，还有气喘。。
感觉不是很普遍，有后遗症基本都发生在哪 ～5% 重症住过院的人群中，没听说过，轻症和无症状的 有啥副作用的，
您穿越来的？美国现在哪里没开放来着？
新定义又出现了
这么热的天，这么多感染，一天几千人死
你戴口罩了吗？还是得疫苗+口罩吧

这要看你在哪个州 接种率如何吧
如果真管用，那么接种率对你个人来说就没什么关系，只有你自己接种没有才有关系
不信的人只会相信他们认为对的数据。
