Anyone with insurance. If they're charging your insurance provider $1,400, then you'll either see that cost passed directly on to you when you get COVID, or see it as an increase in everyone's monthly insurance cost as they spread out what they're paying across their whole customer base. The money's got to come from somewhere. Granted, insurance companies will likely negotiate on the price and not pay that full amount, but it's not exactly a good-faith negotiation if their starting offer is a 10,000% markup.

Also, 2028 is less than 5 years away and COVID is set to be a persistent staple of society like the yearly flu indefinitely. They're basically saying that anyone who gets it while committing the heinous crime of being poor is SOL, even though it costs them almost nothing to produce and was developed using our tax dollars to start with.
