RadVac in the Boston area had an intranasal vaccine out by June of 2020. Not FDA approved/authorized, but quite a few people took it early on with little adverse consequences. About 6 months earlier than the first FDA authorized vaccines became available.

This even happened to big corporations like Sanofi-GSK. The hard part is not to produce some vaccine candidates, but to test the safety and efficacy.

It's just they had to prove safety and efficacy (which to be clear, are paramount for a new medicine), along with scaling up production, before worldwide distribution. https://impfung.biontech.de/en/impfung/project-lightspeed.html https://impfung.biontech.de/en/impfung/project-lightspeed.ht...
