My mistake. Recruitment was completed in July 2020. That would mean 394 days later is probably November 22, 2022, when the Phase 1 would be completed, then vetted and accepted prior to commencing Phase 2. Which needs completion before Phase 3, and then labelling agreement with FDA, etc. all prior to commercial release.
The simpler point is that they simply skipped any semblance of normal drug development, passing over the Phase 1 safety and Phase 2 efficacy studies. Otherwise, many other drugs would get fast tracked like this. The takeaway is that they cannot actually comment on safety in any historical context or legal framework, because it isn't done yet, and they cannot comment on efficacy for the same reason.
I get "pandemic" and all that. What I do not get is how the authorities can fastrack this and not say, in LARGE CAPS, that they are unsure of results over time. And that is the point. Pfizer's legal would not have let the drug be marketed unless it was called a vaccine so there was no liability, because the company simply had no safety data, or efficacy data to rely on. That means they guestimated, just like they do with the flu "vaccine".
