What will it take?

I know a lot of vaccinated people who are strongly anti-mandate.

The thing is, the mandates have no legitimate logical basis as vaccines provide, at best, minimal protection against the spread of Omicron.  There is even evidence to suggest mandates increase the spread as a lot of vaccinated passport carrying people (particularly younger people) take the view that "I'm vaccinated so can't spread Covid" and are therefore more likely to mix & mingle to a far greater extent.

well yes the mandates are legitimate, and yes it is logical.  Whatever protection vaccines provide is better than not, but I leave that one to those who know the science.  
Young (and other) people ignoring rules, thinking they're bullet proof etc is nothing new and is evidence of nothing more than what most recognise as 'young and dumb'.    Doesn't excuse the behaviour or refute the evidence that vaccines and mandates work and are required

Your "whatever protection vaccines provide is better than not" argument in favour of mandates shows incredibly limited powers of reason and logic.  By that same logic, we should reduce the speed limit to zero, as that would reduce the road toll to zero.

The thing is the vaccine does clearly reduce hospitalisation but it also clearly causes harm to some people.  Therefore, it needs to be a personal choice like medical treatment has generally been in free open societies.  My point re. the limited benefit to others of a person being vaccinated is relevant as that determines whether or not it is reasonable for society to impose its collective will on the individual.  In this case, there is just no clear scientific evidence that you're at greater risk of catching Covid from someone choosing to remain unvaccinated (and soon even those who choose not to get the third dose will also be classified as "not fully vaccinated") than you are from a fully vaccinated person.  Therefore, it is immoral to limit peoples freedoms based on their personal choice in this matter.

And to the "it's just a little jab, what are you afraid of" comments: it is equally valid to say "it's just a cold, what are you afraid of", particularly with regard to Omicron.
