The long and the short of it always boils down to, it's not worth the risk to sell to individuals. Because if something goes wrong and someone is injured or killed, the regulatory agencies are going to come down on you like a ton of bricks
I would assume similar practices exist for pharmaceuticals.
But does anyone actually know what these pre-sale contracts look like? They must have some wiggle room in case production doesn't go as well as planned... are there just penalties for late delivery to specific customers, or explicitly tied to total production, or did they literally sell places in the queue, or what?
The hospitals treating Saudi princes are real hospitals. So they can win auctions if it comes down to that, because they are invited to them while the rest of the black market isn't. I don't think real vaccines will come to auction though.
There is one thing left: vaccines that have approval issues. Any vaccine that is somewhat effective by not enough (The Oxford vaccine at 65% efficiency is questionable). The Russian vaccine. Any of many that haven't started phase 3 trails yet. Any vaccine that has safety issues. All are candidates for someone to "leak" to the underground. You will have to consider the risks, but it might be worth it to get it now and then in a year when the better vaccines come to you get that too.
If not from the main production... they had 43538 phase III participants, there must be leftovers, which won't appear in the books as real production... maybe you can route those to important donors of your philanthropic arm, or something? Run some "further trials" in a variety of small clinics, including those catering to visiting Saudis?
Plus actual black market stuff of course, I wonder if any of their refrigerated shipping boxes have gone missing? And, as you say, things like the Russian vaccine are probably already available at a price.
There are 13555k millionaires outside of Europe and US. The 1.9 billion paid by the US government for 100million viles pales in front of what pfizer could earn by catering to the rich.
So, again, my question stands, why wouldn’t pfizer sell directly to customers? What binds them to just deal with governments alone? I ask this as a humble non-millionaire (just to clarify that I wouldn’t benefit from such a scheme in any way) :)
