这是我对雪梅《FDA从来没有批准Pfizer新冠疫苗在美国使用？》一文的评论：

Comirnaty是Pfizer-BioNTech疫苗将使用的商品名称，这在FDA的新闻发布中写得很清楚（Today, the U.S. Food and Drug Administration approved the first COVID-19 vaccine. The vaccine has been known as the Pfizer-BioNTech COVID-19 Vaccine, and will now be marketed as Comirnaty (koe-mir’-na-tee), for the prevention of COVID-19 disease in individuals 16 years of age and older. The vaccine also continues to be available under emergency use authorization (EUA), including for individuals 12 through 15 years of age and for the administration of a third dose in certain immunocompromised individuals）。该新闻还指出：Since Dec. 11, 2020, the Pfizer-BioNTech COVID-19 Vaccine has been available under EUA in individuals 16 years of age and older, and the authorization was expanded to include those 12 through 15 years of age on May 10, 2021.

可见，FDA批准的就是已在美国经紧急授权（EUA）使用的Pfizer-BioNTech疫苗（即华人所称的“辉瑞疫苗”）。

关于这款疫苗并未被FDA批准的说法，USAToday在去年十月有专文辟谣，链接如下：

这本是很简单的事实，为什么还有人听信谣言呢？
