The new analysis relies on the database of Maccabi Healthcare Services, which enrolls about 2.5 million Israelis. The study, led by Tal Patalon and Sivan Gazit at KSM, the system’s research and innovation arm, found in two analyses that people who were vaccinated in January and February were, in June, July, and the first half of August, six to 13 times more likely to get infected than unvaccinated people who were previously infected with the coronavirus. In one analysis, comparing more than 32,000 people in the health system, the risk of developing symptomatic COVID-19 was 27 times higher among the vaccinated, and the risk of hospitalization eight times higher.
强制得过新冠的人打疫苗实在没有必要。

得过再来一针简直金钟附体。

这里涉及到的假设和前提太多了。多用脑子想一想,用一个研究的单一结论得出一个大结论是多么的武断。下面是写给有基本科学思维的人,反疫苗的请自动滚开。
在讨论数据的时候,不同疫苗,对于不同的变种,都不能一概而论。最近的数据是,辉瑞疫苗刚接种完两针两周后对delta的防护率大概是85%,三个月之后降到75%。可以想象6个月之后的效果会进一步变差,这个也是加强针的原因之一。另外辉瑞的疫苗抗体衰减速度大于AZ。我看过几乎所有的研究,包括不同种类疫苗混打先打灭活疫苗,加强针能显著提高抗体水平。所以有理由可以相信,得过新冠的人再打疫苗可以得到类似加强针的效果。当然这个结论需要更多的数据支持。再就是得过新冠的人,比打辉瑞6个月以上的人有更好的免疫能力,但是这个数据和打完疫苗三个月以内的人相比,差距是多少?同时,得过新冠且打过疫苗的人,他们的免疫能力衰减速度又是多少,会不会有所改善?

请教哪篇paper说辉瑞降的比az快?
