Moderna's vaccine is promising, but before phase II, the probability that it will pass all the hurdles is still pretty low, and that's why there are over 60 vaccine developments ongoing in parallel.
The BCG vaccine is indeed no COVID-specific. However, like the other vaccine initiatives, it may yet prove to be effective, and since its safety is already well understood, it can move through the process more quickly. We'll likely know its effectiveness well before any of the other vaccine candidates make it to phase III (Moderna is saying "early summer" for phase III but that really seems extremely unlikely unless your last name rhymes with "rump").
