Do you think there were a bunch of experimental vaccines just floating around on the . . . dark web? ... That's not how it works. The vaccine makers themselves have no interest in distributing unproven vaccines. I myself was highly confident (and posted such on HN) that we would have a successful coronavirus vaccine, based on the scientific information available early in the pandemic. But it wasn't a surety. You must have a randomized trial or you risk very very bad outcomes. Some experimental vaccines (e.g., dengue) actually make the viral infection worse. Some don't work at all (e.g., Sanofi's covid vaccine). Heck Sanofi's vaccine is likely the easiest to manufacture and distribute. If we followed your "plan", it would likely be that most got the ineffective Sanofi vaccine and we would be moving dead bodies around with bull dozers as "vaccinated" people failed to practice social distancing.
