They know this vax protects some people, but it also kills some and makes some others die ... Soon?
So they secretly vaccinated their population in early 2019. (Their citizens are already accustomed to obediently doing whatever government requires.)
At that point they were ready to let the virus out to run through the locals (with minimal impact) and then to the world. In fact they may have only vaxd Wuhan, and planned to lock them down and trap them unless they were headed out to other countries.
Then all they had to do was sit back and control their puppets.
But that would mean they would have died at a faster rate, since the vaxx is seemingly more dangerous than COVID.
COVID = Make believe cases and deaths
Vaxx = Suppressed death/reaction data
I'm just theorizing from a position where the Vax does actually provide some degree of protection. (Not even my belief). But I was thinking that They seem to believe it has some degree of covid protection. (Like they know it'll ultimately kill 30% but that's a number they are happy to extinguish. )
