The Moderna trial had a control group infection rate of 0.6% vs. Pfizer's 0.79%. It doesn't really change the story, but if we are going to split hairs over effectiveness ratings, I wonder how sensitive are they to random variance in the control group outcomes, assuming both drugs are exactly the same (they're not), and both tested populations are exactly the same (they're not).
