Surviving a previous infection provided better protection than vaccination against Covid-19 during the Delta wave, federal health authorities said, citing research showing that both the shots and recovery from the virus provided significant defense. The Centers for Disease Control and Prevention said Wednesday that data from 1.1 million Covid-19 cases in California and New York last year showed people who were unvaccinated and hadn’t previously contracted Covid-19 faced a far greater risk than both people who had gotten the shots and people who had been infected. The data on testing, cases and immunization was collected between May and November, as the Delta variant emerged and became dominant in the U.S., before the more-infectious Omicron variant began to spread widely. The hospitalization data came from more than 50,000 people in just California. https://www.wsj.com/articles/prior-covid-19-infection-offered-better-protection-than-vaccination-during-delta-wave-11642619009
"both the shots and recovery from the virus provided significant defense" vaccine mandate是建立在shots有提供足够保护的前提下，和recovery from the virus 是不是也提供保护没有任何关系。 当然，您要说这个研究结果（如果有效），可以说明感染过的应该与打过疫苗的同样对待，那是完全合理的推论。

Based on personal experiences of COVID twice, I agree. This 3rd time came and gone like it never came - only that same weird old man smell in my throat gave it up.
你是怎么得出疫苗不防重症的结论的？自己读一下这段： COVID-19 hospitalization rates in California were always highest among unvaccinated persons without a previous COVID-19 diagnosis (Table 2) (Figure). In the pre-Delta period during June 13–June 26, for example, compared with hospitalization rates among unvaccinated persons without a previous COVID-19 diagnosis, hospitalization rates were 27.7-fold lower (95% CI = 22.4–33.0) among vaccinated persons without a previous COVID-19 diagnosis, 6.0-fold lower (95% CI = 3.3–8.7) among unvaccinated persons with a previous COVID-19 diagnosis, and 7.1-fold lower (95% CI = 4.0–10.3) among vaccinated persons with a previous COVID-19 diagnosis. However, this pattern also shifted as the Delta variant became predominant. During October 3–16, compared with hospitalization rates among unvaccinated persons without a previous COVID-19 diagnosis, hospitalization rates were 19.8-fold lower (95% CI = 18.2–21.4) among vaccinated persons without a previous COVID-19 diagnosis, 55.3-fold lower (95% CI = 27.3–83.3) among unvaccinated persons with a previous COVID-19 diagnosis, and 57.5-fold lower (95% CI = 29.2–85.8) among vaccinated persons with a previous COVID-19 diagnosis.

疫苗是根据最早的武汉病毒株研发的，在Delta之前疫苗的保护确实要比自然感染保护更强更好，这在这次CDC的研究数据中得到了证明： During the week beginning May 30, 2021, compared with COVID-19 case rates among unvaccinated persons without a previous COVID-19 diagnosis, COVID-19 case rates were 19.9-fold (California) and 18.4-fold (New York) lower among vaccinated persons without a previous diagnosis; rates were 7.2-fold (California) and 9.9-fold (New York) lower among unvaccinated persons with a previous COVID-19 diagnosis and 9.6-fold (California) and 8.5-fold (New York) lower among vaccinated persons with a previous COVID-19 diagnosis (Table 2). In the pre-Delta period during June 13–June 26, for example, compared with hospitalization rates among unvaccinated persons without a previous COVID-19 diagnosis, hospitalization rates were 27.7-fold lower (95% CI = 22.4–33.0) among vaccinated persons without a previous COVID-19 diagnosis, 6.0-fold lower (95% CI = 3.3–8.7) among unvaccinated persons with a previous COVID-19 diagnosis, and 7.1-fold lower (95% CI = 4.0–10.3) among vaccinated persons with a previous COVID-19 diagnosis.

这个疫苗也奇怪，专门对美国人有效，别的国家就没这么有效
而且这个疫苗的副作用也没有完全研究好吧，长期的不说了都没数据，短期的就我知道的我身边的，有高烧好几周不退的，有出疹子的，还有打了第三针心跳过快好几天的，也不知道有没有被统计到疫苗副作用里
mrna疫苗一年来打死的人数超过过去二十年所有其他疫苗的总和，这还是在官方统计很不完全的情况下 用mrna疫苗类比其他疫苗，不合适
而且covid高危人群，和疫苗副作用高危人群，并不重合。本来得covid不会死的人，强制疫苗打死了打残了要怎么说呢？
天花这种死亡率不是一个数量级上的疾病根本无从比较
数据 不统计就没有。这些”数据”说不定那天就发生在你身边，发生在你头上。不要怕，反正都是网友胡编的，不存在的
🛋️ 沙发板凳
hahhahaha
LOL!
LMAO 或者另一种survival bias 的说法？
小心鸡汤有毒
在英国和口罩mandate一样， 已经完蛋了
美国的盎格鲁撒克逊纯度低得多， 不过历史上也一直是跟着学地。
没完没了了
嗯。以后必须证明得过才能出国
不太可能 这个事儿结束了
关键词抓得太准了！ 笑死。
事情总要理性看待吧。癌症也死人啊，是不是就天天把自己锁家里，吃最健康的有机食品，喝矿泉水过日子算了？

关键论点是反驳了以前所谓的疫苗比得过的抗体更有效的说法。 你要反驳就拿出数据来。 疫苗教的那句经典台词怎么说来着： 要相信科学。
是啊，这是我们顶锅盖早就得出的观点，虽然被围攻但事实证明是对的，现在终于风向转了，不提疫苗了，转推自然感染和口罩了。。。
"both the shots and recovery from the virus provided significant defense"
vaccine mandate是建立在shots有提供足够保护的前提下，和recovery from the virus 是不是也提供保护没有任何关系。
当然，您要说这个研究结果（如果有效），可以说明感染过的应该与打过疫苗的同样对待，那是完全合理的推论。
肥胖导致各种疾病，那政府能不能下令体脂超过某数据的人不被允许吃不利于健康的食物，然后规定所有买食物的人必须出事1个月内的体脂数据，你认为怎么样？
疫苗不保护感染，更不防止传播。要不要打疫苗保护重症应该是个人选择，而不是政府强制。
乙肝是终身带毒吧。那就谈不上保护持久了。 Covid现在没这么说吧
主要是得了的人也有轻重之说，有paper说，无症状感染的人产生的抗体要低不少，reinfect的可能性高些，病了一场的人倒的确一段时间内不需要打了。
没听过这个说法
What doesn't kill you, makes you stronger. 已经被kill的，当然不可能强。
这个研究说的是一个人感染了covid康复后获得的protection比疫苗好，是纵向比较
乙肝一旦感染终身携带，哪有保护作用？
疫苗是用原始病毒做的，在早期的确更有效，抗体浓度更高，95%的有效率都是实打实的数据。这里说的是Delta, Delta让疫苗产生的有效抗体降了四倍，所以自然感染Delta产生的有效抗体可能会高一些也没错啊。
那问题不是有很多例子反复的感染么 每一波都中招 他们免疫了啥 一变种就不免疫了啊 到底这个时间有多长呢 问了家庭医生半天也没说出来个啥 主要是这一波很多孩子上学得了O的话 那他们还需要打疫苗吗？
我觉得不同年龄组要分别来看，比如老年人死亡率这么高，那对大部分老年人来说肯定打疫苗的好处更大
32岁的健康人死于Covid的概率， 只有产妇死于难产概率的两百分之一。
这么小的概率让你碰上了哈， 真够倒霉的。
我也得了，booster也是照样打。
LOL
问题是没打疫苗重症了咋办？不像其他癌症慢性病，这个突发起来乌央乌央的医院满的快，就跟洪水一样。
国家强制已无效， 可是我们公司说还是强制 除了几个州政府不许强制的 我看了眼 只记得田纳西的 员工可以不再强制疫苗
讨论这个问题就是个无底洞，两方都会有道理支持自己观点。如果一个人打了疫苗有严重反应，政府能负责不？要是能的话，强制起来也不会那么费劲。
问题是感染有很多种 -- 有的很轻基本没症状，有的死去活来进了ICU。 就像疫苗，你不能说我打两针，但都是1/2的剂量就算fully vaccinated了吧。自然免疫很难定量地去规范。
星巴克美国店（雇员）已经不要求了。。。
肥胖不会传染人
但是现在支持强制疫苗的论据也不是防止传染
COVID 谁知道呢. 也许20年后科学发达了, 发现终身带病毒潜伏在目前测不到的地方,只是没发作
那要完整活下来才算
疫苗不防传染啊。想打可以打，选择不打的，就不打啊。艾滋患者都不被强制不可以和人有性行为了。艾滋不可怕？
是啊，那个什么熊的出来走几圈，还是被关在了那个cell 不出来了。
她其实写孩子那一篇 人就是这么个意思 但是业内人士不好说鼓励你们不打 我一个素人 发了两次帖子 都心里觉得担不起这个责任要求版主删帖了
那个是最好笑的，但是for some reason，华人上被捧成专家。。。她的qualification是啥？
Delta 时期也是说疫苗比自然感染效果好， 版上也看到过。
居然看笑了，哈哈哈哈
重什么磅啊？ 这不是很合理吗？ 一个是真的打了一场战， 一边是预演，你说过后， 哪边会强一点？

在英国口罩也不强制执行了，以后其他国家也会仿效和跟随的。
应用到个体都不准。
这什么脑子啊。癌症病人会几十万的一起发病同时住院吗？怕的不就是冲击医疗系统吗？
没错。我也是因为这个掉了下巴，觉得哪里都是靠宣传愚民啊。
Biden政府被Pfizer/Moderna糊弄了booster的钱，现在才醒悟过来。 Pfizer/Moderna不推出针对omicron变种的疫苗是不行的，老是用原始配方忽悠钱，吃相难看。
是这个意思 哪有重磅

要不要问问打了疫苗死了的人和残废的？
这个口罩mandate我还是希望能再继续的也不耽误啥事儿啊
这个数据中，with previous covid diagnosis组，不管是不是vaccinated，结果都差不多，难道这说明，得过一次covid的人的更容易得第二次，不管是不是vaccinated?
32岁covid死亡率0.2%，产妇难产概率40%吗？ 张口就瞎说
我觉得大多数在Delta和Omicron问世以前再感染的人无论打不打疫苗可能在习惯上比较不重视自我保护。
