Assuming they know what the vaccine does and they want to give this to billions of people, why would all human governments want to give AIDS to billions of people?
Well we know what spiritual forces are behind human government thrones. The god of this world, and his minions.
His goal is to kill , steal, and destroy. He is a murderer. He has put it on the hearts of the insanely wealthy and powerful to cull mankind.
They TRULY want to kill BILLIONS of human beings. And what's left, they want to utterly enslave.
We have all of human history as proof that governments are evil, and they kill their citizens without remorse.
