There's still a ways to go in the study itself. They want to achieve 50 more infection and extrapolate out but the early data is very promising. Also, it's not political. Pfizer is not part of Warp Speed and took no government aide.
In a perfect world where everything works, production and distribution ramp up in early 2021, medical staff and the vulnerable get it first in the Spring and its available to the general populace in the Summer. If all goes well, the world starts to return to normal in Fall 2021.
God's speed to all.
