Is it zero sum? People keep saying that but if you give the suppliers more money, that allows them to scale up more and faster. It's not a given that they're just at 100 percent of their production capacity.
Actually, they do seem to be at their limit. There have been articles about this (which I merely glanced over). Scaling up manufacturing for vaccines, especially new RNA based ones, isn't something that scales infinitely with money. Not in the short or medium term, at least. In some cases, scaling up required downscaling of current production.
Searched for the well written article I've seen, to link it here, but I'm only getting SEO bullshit.
