Is There a FDA Forbidding Stanford From Using Its Own Tesks?

The strand that i've been reading has a lot of fda and c d c bungling in it. I mean, you know, everything is either forbidden or mandatory. If we had been, if you'd been allowed to try it on experimental basis, think how many people could have we invented this vaccine overnight. And going forward, why do we not have a vaccine for the delta variant? Are we really going to have to have a full year of three stage clinical trials for every single variant that comes along?
