我搞统计的,感觉倒是相反。 CDC常年出的几个数据库,都还算权威,我接触过的有the Behavioral Risk Factor Surveillance System (BRFSS), the National Health Interview Survey (NHIS)。从 他们的采样来看,大人的结论应该比较准,小孩的反而难说,不过即使不准,也差不了 很多,不至于5个百分点。 啊呀,怎么歪成学术帖了,其实本意是单纯地觉得这个文章标题起的很吓人而已。
The flu virus is different every year. You may get it again. But you are right about one thing, the old, young, pregnant need the vaccine more than young and healthy people like you.
