There's a separate element of Warp Speed that nobody is discussing. It's not about funding the development, but about allowing use on humans with reduced trials beforehand. That part was enormously successful.

That's not operation Warp speed. That's pandemic 101 from the WHO.

And it's not reduced trials, it's doing them simultaneously.

I mentioned it before in another comment 3 hours ago: https://news.ycombinator.com/item?id=30141967

BioNTech did receive significant funding from the German government, however.

That's not related to Warp speed.

Those are subsidies for eg. doing simultaneous clinical trials and to compensate it's additional costs.
