> missing the point, that there is no risk for the individual to denying COVID or vaccinations
I would argue that there is no subjectively felt risk.
It isn't that we as society decided to care for these people when they fall ill. They nonetheless have a higher risk of dying from an infection with Sars-CoV-2. The risk is there - they just do not feel it, because the felt risk of some wonky chip implant or other imagined side effects feels bigger.
These people have over time constructed a world view for themselves (with lots of help from YouTube, Facebook and other places to find "inspiration" for said world view) that is not only constructed around this one fear.
To me esp. these COVID deniers feel (and I have no data to back that up) like they are grasping for straws of (felt) control in a world they feel is out of their control. They say: I do not let the state vax me. Because now they are in control of at least something. Then they need to make the fact go away that they just handed the control over to a virus. So the nearly logical next step is to either not believe the virus is real, or to believe it doesn't hit you or believe, if it hits you your immune system is fit enough to deal with it, because it isn't as dangerous as the big bad state wants you to believe.
It is a rabbit hole to go down - one fear/believe/feeling out of control leading to the next piece of the puzzle in your new world view were you are in control.
And the politicians doing the exact opposite thing that scientists recommend as well as science (by definition) not being able to provide 100% certainty and easy answers (because well life isn't made up of easy answers) are not equipped to make these people feel in control (because they are not - nobody is).
So I feel (as said - I have no data) the problem lies deeper. Either (some) humans just want/need easy answers or we as a society have not learned to teach ourselves from early on, that there are no certainties and control is a myth and how to deal with greys and uncertainty.
On the other hand - if one actually looks at the numbers, these people may seem loud and a big mass on said (social) platforms (probably amplified by the algorithms) but are a very tiny minority in reality.
