While I agree with most of this comment (the covid vaccine is the result of the world working for the betterment of society, succeeding where the "profit" motivation has utterly failed), the idea that HIV, malaria, and cancer such have not been treated because they're not "profitable" to cure has always struck me as verging on conspiracy. The first company to produce a definitive cure would no doubt make billions in profit. The problem is specifically with mRNA vaccines: the cost of research into it was so high with little guaranteed payoff. The problem was that the risk-reward calculation was showing that none of the money invested into mRNA vaccines had turned a profit yet, so despite the promise of the technology and the fact that medicine at large would greatly benefit from a single breakthrough vaccine, no single company was willing to put in the investment since they wouldn't reap the full rewards.
