According to the Catholic Church, should 'vaccine passports' be contrary to Natural Moral Law?

I've read a lot of shocking stories lately [from Lifesitenews](https://www.lifesitenews.com/news/sweden-vaccine-passports-will-probably-be-required-for-shopping-eating-out-travel-meeting-loved-ones) and the like about the age of vaccine passports. I think they just assume that the reader will have an innate revulsion to them and don't go into whether or not a thing is morally justifiable. So for that purpose, I'm asking here. According to the constant tradition of the Catholic Church, the interpreter of the [Natural Moral Law](https://www.vatican.va/archive/ccc_css/archive/catechism/p3s1c3a1.htm) (which is written on the hearts of all men and women and "expresses the dignity of the person and determines the basis for his fundamental rights and duties"), does a "vaccine passport" comport with human dignity?
