An honest perusal of this study will more than likely lead you to one conclusion: That there's never actually going to be a vaccine released for the Wuhan coronavirus (COVID-19) because making a truly effective one would never work. Of course, one could still be released that's claimed to be effective, but any genuine look at it by regulators would surely reveal that it's bogus, resulting in its rejection.
What this all means for the release of Americans from lockdown remains to be seen, and certainly doesn't look promising. But the more we can get the following information out to the general public, the better our chances of blowing the lid on the vaccine charade that's now quite literally keeping people as prisoners inside their own homes.
If you read through this paper, which was actually published in a journal called Coronaviruses, you'll notice that one of the stated requirements for an effective coronavirus vaccine is to make it live attenuated, meaning it would have to contain live, yet weakened, bits of the actual virus.
