The virus is man made.
I was designed to be not too dangerous but just worse than regular flu.
If it were too dangerous then they could wipe themselves out.
Also, I expect they developed an antidote as well - for their use only, of course.
The idea was to hype the virus which they did with billions of media stories far exceeding any other epidemic e.g. Ebola, Zika.
The vaccine is part of the threat. That is why they are working so hard to give it to everyone asap before we find out what is happening.
I imagine that there will be another virus along later that will combine with the vaccine and cause devastation. Of course, "they" will not have been vaccinated so will be unaffected.
My take - based on guesswork:
