Between January 1 and April 30, 46 US states and territories had reported to the Centers for Disease Control and Prevention that a total of 10,262 individuals had tested positive for coronavirus despite being fully vaccinated, in what is known as a breakthrough infection. The agency said in a report on Tuesday that 63 per cent of such cases occurred in females and that the median age of all patients was 58, which “reflects” the age and sex distribution of the fully vaccinated US population. Of the reported breakthrough cases, 27 per cent of individuals were asymptomatic, 10 per cent were known to be hospitalised and 160 people, or 2 per cent, died. Among the 995 hospitalised patients, 289 were asymptomatic or admitted to hospital for a reason unrelated to coronavirus, the CDC said. The median age of patients who died was 82, and 28 of these patients were asymptomatic or died from a cause unrelated to Covid-19. Genomic sequencing data were available for 555, or 5 per cent, of all reported breakthrough infections during the January 1 to April 30 period and showed that 64 per cent of infections stemmed from so-called variants of concern. More than half of these cases were related to the strain of Covid-19 that was first identified in the UK last year and is now the predominant variant in the US. The CDC said breakthrough cases are to be expected “especially before population immunity reaches sufficient levels to further decrease transmission” and that these occur in “only a small fraction” of all inoculated individuals, accounting for a “small percentage” of all Covid-19 cases. As of April 30, about 101m Americans have been fully vaccinated, which is defined as two weeks since an individual has received their final jab. That total has risen to almost 131m, or 39.3 per cent of the US population, according to CDC data as of Monday morning. The report’s findings were subject to at least two limitations, the CDC acknowledged. First, the number of reported breakthrough infections was probably a “substantial undercount” because the national surveillance system relies on passive and voluntary reporting — individuals who are asymptomatic or only have a mild illness may not seek testing. Second, genomic sequencing data are only available for a small proportion of reported Covid-19 cases.

首先，疫苗肯定是有效的。 然而，这篇文章的数据并不能得出任何关于有效性的结论。因为10000个疫苗后病例不代表另外的9999万人没得病。“the number of reported breakthrough infections was probably a “substantial undercount” because the national surveillance system relies on passive and voluntary reporting” 至于这个undercount到底是1倍还是10倍还是100倍，没人知道。所以这些数据没法的出任何关于有效性的结论。

看上去很吓人，Vaccine Adverse Event Reporting System (VAERS)里的数据吧？ 基数是什么，怎么才几千人？ 如果是VAERS， 要知道VAERS里面有disclaimer： “The reports may contain information that is incomplete, inaccurate, coincidental, or unverifiable。 也就是说， VAERS里面哪怕有报告说打了疫苗以后死亡的，不等于疫苗是死亡诱因。 这个需要调查。

对比这四个月的感染人数，疫苗效果应该不难判断。

“Breakthrough” Covid cases relatively rare in the US, says CDC report Peter Wells in New York
More than 10,000 “breakthrough” cases of coronavirus in the US were reported to the country’s top public health agency by the end of April, at which time about 100m Americans had been fully vaccinated. Between January 1 and April 30, 46 US states and territories had reported to the Centers for Disease Control and Prevention that a total of 10,262 individuals had tested positive for coronavirus despite being fully vaccinated, in what is known as a breakthrough infection.

CDC暗改了PCR test guideline，原来最多跑40-50个cycle，今年3月开始规定<28。
这种图连个出处都没有，而且0-17岁不是搞笑么？0-12岁疫苗都没有打。 按照0.8%，30这个数字看，总人数也就3000-4000. 这个基数代表什么意思呢？

反正严重到要进医院的case那肯定得测新冠，所以住院人数995人统计中包含了289人住院原因不是因为新冠的。 1亿人打了疫苗，只有700人需要因为新冠住院，而且死的中位年龄 > 80岁，这个数字不是很牛逼么？

是<28不要求提交样品做全基因测序，你不懂不要胡说。
PCR的规则没有改。
