From what I know a pandemic such as this one cannot be monetize by pharmaceutical businesses if they find an antidote. That would violate a lot of international laws which a lot of countries already agreed and the company's CEO might be charged such as crimes against humanity. If they found a cure the best thing the company will get is either a subsidy for their research as well as some compensation for their efforts, they might profit a little but they won't be billionaires because of it as they cannot make this antidote/cure exclusive to the rich, this cure will be everyone's right to receive.
