A tech comparison would be 4 or maybe 3 nm chips. Imagine everybody in the world would fork over 200B and order 7 billion chips this year... your constraint in that case is the manufacturing equipment and there are only so many experts in that area. The vaccine technologies we are using are scaled for the first time so you don’t have a big pool of experts or companies. The Chinese vaccine is probably the one best suited for scaling up and they are doing that rapidly.
