I don’t think that the state should have the right to vaccinate people against their will
There are lots of areas in life where the state mandates that people do or don't do a certain thing. If it didn't there would be no need for prisons. And I certainly wouldn't pay taxes if they weren't obligatory.
I think there are two issues. One, to what extent should the state interfere with individual freedom. You might say the freedom to go drink-driving should be curtailed because it can harm the person doing it and those around them too. But that's the same with vaccine-refusers - they're more likely to die of Covid than of the vaccine, and unvaccinated people are more likely to spread the disease. In both examples the state would be interfering in people's lives, stopping them doing what they chose with their bodies.
Two, if you accept the state should have the power to prohibit or mandate things, is the vaccination an example where it should be used? I don't know where the line should be drawn - my drink driving example will be accepted as legitimate state interference by many, so why not interfere on something else that will save lives?
Do people who voluntarily have the vaccine really care if reluctant people are "forced" to? (I'm not sure they will actually be forced into it, Austria(?) for example just fine people who refuse but don't strap them down and inject them.) Personally, I'm double-jabbed, and I'd happily have the booster if they fucking open a vaccination centre in my town rather than expecting me to get on a packed bus for an hour to head to the main SHOPPING CENTRE of a nearby city when it's THE BUSIEST SHOPPING PERIOD OF THE YEAR AND COVID IS SPREADING WIDELY. It doesn't matter to me very much whether others are forced to be vaccinated, just as I don't object when someone I know is prosecuted for driving over the limit. The rules don't affect me because I didn't break them, in fact it is better for me if they are enforced.
