It's easily conceivable that billionaires have been pushing to be 'in the loop' on the meds from the start, and will have gained access long ago to whatever was used in the most promising trials. They can take it as soon as the insider doctors flag that it's ok, likely many weeks before any public announcement, and certainly before any governmental validation.

The value of said vaccines are considerable, there's massive money involved, I wonder if the R&D institutions themselves may have been able to find a loophole to allow for it.

With the sheer number of doctors and patients involved in the trial, and vials worth possibly $100-500K on the black market ... it's bound to get out.

And frankly, who cares? A couple thousand early vaccines is basically meaningless from a public health standpoint. It might even be moral to have publicly auctioned off the first mini batch and put the money into production. It's rational because the 'willingness to pay' of some billionaires for the almost arbitrary early access to a vaccine which will soon be cheap and plentiful ... works well as a 'win win' both for the buyer, and society.
