很遗憾,这是美国CDC昨天的报告,疫苗的效果也是差强人意。图中那些浅色是打两针疫苗14天以后的感染者,在这份报告中调查的469位感染患者中占74%。
疫苗的效果不够强大,不仅是中国等国的灭活疫苗,西方的mRNA疫苗以前的效果好,恐怕也只是因为delta还没到。面对Delta,各种疫苗:防感染,重症,死亡等各项数据重新检验比较一下吧。
我不反对疫苗,但是无论哪种疫苗的数据,应当实事求是,而不是到处cherry picking.
In July 2021, following multiple large public events in a Barnstable County, Massachusetts, town, 469 COVID-19 cases were identified among Massachusetts residents who had traveled to the town during July 3–17; 346 (74%) occurred in fully vaccinated persons. Testing identified the Delta variant in 90% of specimens from 133 patients. Cycle threshold values were similar among specimens from patients who were fully vaccinated and those who were not.
