In my country you need to show that your kid is vaccinated against e.g. Polio before you can let him/her go to daycare. To me, it makes perfect sense, that somebody who wants to go to e.g. a music festival in 2022 without a face mask, should be able to prove that he is vaccinated (assuming vaccinated people are not infectious, which still needs to be shown, but this is quite likely). Keeping a record of those who refused vaccination might not be necessary for this. In fact, somebody who refused vaccination is as much as a health risk as somebody who has not (yet) the possibility to get vaccinated. But vaccinated people should have the possibility to prove that they are vaccinated and current social distancing rules should no longer apply to these people.
