Probably those people in the tech industry and are anxious to have the vaccine as early as possible. If it's free then there is a possibility that it will somehow run supplies. Some people will probably wait for a lot longer than others.
But 1000usd for a vaccine is too much. I had news that 1 Moderna vaccine sells at 75usd only.
$75 is the price for which Moderna sells the vaccine to the governments around the world. That doesn't mean that it will be available privately for that much. As far as I know, none of the markets have been made available for private purchase. If that was the case, then we don't be reading about these ridiculous stories and people won't be getting scammed in the name of COVID 19 vaccines.
