I think most European countries do. I know for certain that the UK does[1] as well as Germany[2] and Austria[3].

But I see no problem with mandating vaccination or some other, equally strong, way of reducing transmission risk for participation in public events. In this case the individual is given a choice in how they help protect others.
Some people call also the second instance "mandatory vaccination" and object to it on the basis of body autonomy, which honestly doesn't make much sense since the discussion is about how the right to participate can be restricted. And "you are more likely than others to make everyone else sick" is a pretty legitimate reason to restricts someone's right to attend.
Since the vaccination doesn't help against spread, the argument is not true in my opinion.
Can you provide a source for this statement? As far as I know, even though not 100% effective against infections and virus shedding, the vaccines do help against spread so I'd like to know if I'm misinformed.
I don't agree with this statement. However, I certainly think there should be an exception to vaccines for people who have aquired natural immunity. In Hungary, if you have a documented recovery from infection, you are also granted an immunity card that can be used to exempt you from pandemic restrictions. I don't know how many other countries are using this approach.
While I don't like the idea of any kind of mandatory medical treatment, there IS public health value in ensuring that everyone partaking in potential super spreading events is immune.
