Given the USA's total failure at the presumably easier task of wide-scale testing, the notion that we could manufacture and distribute a novel vaccine in this time frame seems completely impossible. Maybe other countries could have success.
How much of that failure was manufacturing capacity, vs. bureaucracy? IIRC there was a California lab doing some testing that was shut down by the CDC... so manufacturing wasn't the bottleneck (maybe it's now? I don't know)
The federal government has already sent billions to vaccine manufacturers to get the ball rolling. It's named "Operation Warp Speed" and the goal is to have 300 million doses of a vaccine by January.
