Liability is a concept. If the vaccines cause you harm, then the vaccine company is liable. And as with all concepts, yes - they are defined by laws and statues so that society can function and the rules of the game can be determined. Vaccine companies changed their rules so they don't play the liability game like everyone else. Maybe fast food restaurants shouldn't be liable when they poison people too?
