There are three elements to this story now, first of course, the fact that vaccines are not safe actually goes viral across many platforms across the world.
Since vaccines are an international level political subject, the system goes into overdrive to shut it down, this can be deleting posts or putting out propaganda with so called experts views to counter the story in a damage limiting way. However this time Blockchain social media was used to prevent the story from being wiped off the internet which just makes the whole cover up attempt look worse that it could have been, if they only did the right thing. Stories such as this or for example Police corruption scandals, where the action taken is never about fixing the problem, but giving the appearance by pretending to, is for one reason only, to get confidence back by the people. Getting the confidence back and fixing the problem are not the same thing, so an eye has to be kept to see what actually happens as the story goes quiet, rather than what is said will happen at its peak.
This lesson is one which serves bockchain social media platforms and gives the governments something else to focus on, as no doubt they will become more of a target over time..
