I don't think the FDAs approval process before was some kind of ideal, so why should I regard deviation from it as that horrible? At this point the original vaccine has been used safely on billions of people, so there isn't much more to be said about it's relative safety.
But on the FDA, it is much slower to approve drugs than in say Europe. And this is NOT a net benefit IMO. It's too bureaucratic. Do we need an agency regulating drugs? Absolutely. Is the present FDA ideal? I don't think so, it is too slow. But then is the U.S. as it currently is capable of reforming institutions, not dismantling or bulldozing them in a fit, sure we can do that, but reforming? I don't think so really. So we'll probably just have to live with the FDA as it is. There are exceptions to it being too slow to approve drugs, like it approving an Alzheimer's drug that likely doesn't even work, but I don't even know what corruption that was.
