Pfizer expects to cut Covid-19 vaccine production time by close to 50%

I wonder if we are anywhere close to the economically efficient production rate for vaccines (where the direct economic benefits more than offset the direct costs).

There is a pretty clear case that it is the minimum rate we should be aiming for.

I guess it is hard to tell when they are still improving the process so dramatically.
