This is what snake oil scams are. They make you think that it's a cure, when in reality it doesn't matter to the salesman whether it is or isn't. If the scammer happens upon the cure for COVID, that's lucky for them, but that isn't their goal. That's why we have regulatory agencies (who theoretically don't have a profit incentive to push false narratives) that control the trial periods. The unfortunate reality is that people who are affected by the (very real!) fear of becoming infected, disabled, or killed by the virus might make decisions about risks which they haven't been informed. In this case, for example, there may be a risk that there are downsides and absolutely no upside. That's what the testing periods are for. Please keep in mind I'm not talking about this specific instance. Here is looks like it's mostly political puffery and the vaccine is going through trials as it should.
