I think, (or hope rather) that the mandates are well meaning, no I don't think this is dictatorship, rather I'm addressing your more "meta" point about social responsibility and the perils of one group being able to dictate to others without input.

As in, we can't just say "We have some social responsibilities so you must XX per the authorities" when XX is self serving, counterproductive, useless or harmful. We have an individual right, and responsibility, to weigh the dictates we are given at some point, perhaps not on all issues, but on some.

Other vaccines were not taken in to market in this manner. It is a novel vaccine.
