Unless the approved vaccines are very ineffective, there are actually ethical problems with that. I think there’s like a 4-5 month window to start and complete any further phase 3 trials on new vaccines - after that, need to do them in some other country that lacks access to approved vaccines. Or, run their trials against an approved vaccine instead of against placebo. Now you’re trying to prove superiority of your vaccine against the approved one, if the approved one is 50% effective and you think yours is 70% effective, you might need a trial even larger than 30,000 for enough statistical power. But if the rate of new infections is coming down due to vaccination or other, how long will it take and how much will it cost to enroll 50,000 subjects . . . and if someone is out there selling vaccine at cost (as Astrazeneca has committed to do for the first year I think) and has ramped up supply to many billions of doses/yr, how much money can you make when your vaccine finally gets approved in (maybe) 2H2021? Your vaccine will need to be really, clearly superior. Tough bar to clear.

Yep. But to get people, they will pay them...and some people need the money.
I think the Moderna will get approved first, but as you said, they don't have the capacity. Most people will probably end up with the J&J vaccine.
