I don't buy it. I think this COVID is a double-edged sword. On one side you have the left that is using it to push their agenda, so their operatives all get sick from it to reinforce the fear. On the other side you have people like DJT, Rudy, Kayleigh, etc…, using it for their own purpose - a purpose we're not aware of. It gets them out of the public though, and gives a convenient reason why they have to vanish for a while. And of course, the left can't call them out because they're using it too.
As for the vaccine, I think it'll eventually be used to expose the evil intent of big pharma. Unfortunately, people are going to die and suffer horribly from taking it. In war their are casualties though, and in this case, it's probably the lowest denominator of society - the gullible, fearful sheep. Other than them, who the hell would take it? After enough of them die or become horribly ill, a more thorough, independent investigation into the vaccine will take place. At least this is my theory as to why Trump is currently endorsing it.
