I understand the definition of the word, but it is ceases to be the definition of the word you chose when they no longer fully predict what the results of their "practicing", or experimenting if you prefer, will reasonably be. They decided to inject a modified version of the vaccine into millions of people in the name of efficiency (and doubtlessly I would guess there is a corporate profit somewhere in there) with no way of knowing or predicting that 12 years down the line that it would cause this.
Most doctors these days unfortunately don't and only blindly follow what the latest salespeople tell them to do (based on profit margins) or what the government prescribes based on short term studies (that have no way of predicting the long term ramifications of their decisions). How many medical class-action suits have there been over bad medication (and vaccines) prescribed before we wake up and realize that the system we blindly believe is protecting us is failing in it's mission (or that's it's mission has changed without our knowledge)?
Where we used to have conversations with doctor's and had a say in our actual care we instead are treated to a factory style healthcare that operates and treats people like a machine.
