This flow chart is not quite accurate, or at least is misleading. There is more to a distinction between EUA and full FDA approval than where manufacturing happens. The FDA's own website[0] says:

> The EUA process is different than an FDA approval or clearance. Under an EUA, in an emergency, the FDA makes a product available to the public based on the best available evidence, without waiting for all the evidence that would be needed for FDA approval or clearance.

I don't post this to spread doubt about the EUA and am fully confident in the safety and efficacy of these vaccines. But as written, this website would seem to suggest that the only difference is when production happens - which is not accurate.
