Moderna has the same setup. They just happened to be able and willing to raise huge amounts of money (and play ball with the .gov) to produce it themselves. It's also why Pfizer is claiming they can produce a billion vaccines over the next year while Moderna is only saying they can do 100 million.
From the linked article: "Moderna said it could potentially manufacture 1bn doses by the end of 2021, adding to a further 1.3bn from Pfizer/BioNTech in the same timeframe."
Given the timelines and uncertainty, I don't think 1B and 1.3B are materially different. Both require 2 doses per vaccination.
Oh great, capitalism at it's best: there's an acute crisis, we might have the solution, but if we don't solve it vertically integrated we would have to share the spoils with a cooperation partner. This can't happen, quick! Bring in the investors!
Take a step back. Why did Moderna founders invest in research and technology? Are they selfless idealists? Probably not, at least that is not the only driving motivator. And even if they are, they still want the company to earn money in order to invest it into more research.
Bottom line is they want the company to be successful, so their long-term plan is to profit from making drugs. If they lived in a socialist economy where no such profit was possible, they would not have bothered, and then there would be no cure. If that is the world you prefer to live in, you have options (North Korea, Cuba and Venezuela currently, the rest having collapsed or transitioned to free market some time ago).
