we have a related case in halakha of “almost” forcing someone to do the right thing despite the explicit autonomy – beat up the husband until he says “I _want_ to give a get”. Is this because another person is affected?
If you hold by the above analogy, presuming there are some consequences of non-vaccination for other people (taxing hospitals, reducing transmission even somewhat – and more for Delta that was out there at least as of last week), then nudging them – require for jobs, flying, eating out – is ok and is not the same as vaccinating by force.
