Only the ones at the top. The medical profession is simply doing what it is told to by the WHO, there is no need to for them to know about the scam in order for them to be complicit in it.
That's the sheer genius of this scam, the Globalists spent the past century putting all the pieces in place, so that when it was go-time, they simply had to use those pieces accordingly.
The world leaders are too scared not to comply with the program in case they receive the Trump treatment, and get labelled responsible for the deaths of thousands.
The perfect crime, on so many levels.
