Not even Pfizer or Moderna. It is in fact coming from my hometown Tübingen. PFE didn`t develop the vaccine, it was Biontech
You are correct Biontech did the "R" in R&D.
It's more than just a couple of months. A Biontech just doesn't find $2B laying around. The experience Pfizer has interfacing with the FDA, chopped off months. Probably even more important, the ability of a Pfizer to ramp up GMP manufacturing quickly.
What is the split for Biontech on the profits for the vaccine... 50%, 20%, 10%?
Assuming they don't run into any off target problems.
Drumpf never caught onto the idea it's a global economy. No one country has a monopoly on science.
