If I have to take a guess, by the time either of you even can have access to it, it will already had been tried out on hundreds of thousands of people for weeks or months: doctors, nurses, seniors and people with chronic illness. I doubt either of you can pre-order or get day-one access to it even if you wanted to.
I know right? It's almost like there's this thing...called medical trials or something, and they do it in stages to test the efficacy and lethality of a medication before they send it out.
Now, to be fair, this one IS being accelerated a lot, so there is always a chance of long term, unforeseen complications down the road. But, similar to the cocktail of drugs they gave US military being deployed to the middle east, to protect them against things like anthrax and the like, they weren't really sure what it might do to someone say, 10+ years later. But they weren't worried about that, as they needed it NOW, to give to troops NOW. That's why most regular trials take years, to try and account for long term complications, that don't manifest right away.
But, they have to weigh the pros and cons of "give a drug with the potential for long term complications (but also with the potential to NOT have any) to stop a plague now? Or hold off and do more long term studies to insure no long term problems...and let people die now." It's not an easy question to answer, or at least, it's not one with a great answer either way.
We could end up with something similar to agent orange in 20+ years, where people start having widespread, long term problems, that nobody knows about until decades later. Or, we might not.
