Regardless of their motives they're all subject to the same regulatory system so they can only stray so far for so long from the net effect of the incentives and remain not bankrupt and being auctioned to pay back creditors.
I mean different countries have different regulatory systems....

It seems to me that the leading vaccine manufacturers, who spend billions of dollars yearly in order to lobby US lawmakers that establish the bureaucracy the article is complaining about, are interested in just that (maximizing profits).
It doesn't really matter much if there are individuals or other organizations interested in curing disease, when we have a system that allows for legal bribery of lawmakers, and other individuals / organizations with more money that value profits over anything else.
Vaccine companies are very interested in preventing disease not the kind of extended treatment people so often expect the healthcare industry to be looking for. They have an endless stream of new people being born every year so have no interest in people getting sick.
> If people aren't getting sick
People also get sick outside the US.
People still get vaccinated in the US for diseases with effectively zero new US cases because they haven’t been eradicated worldwide and would come back as soon as we stop vaccinating people.
