If it helps to put some of you more at ease about vaccine passports, back in the day I travelled quite a bit in Africa and some in south-east Asia and we all had these little booklets with a record of all our shots in them. They weren't a big deal, nothing nefarious about them. It was mostly to show you had your yellow fever shot and I used mine to stash US $10 bills which sometimes helped border guards see their way clear to an entry stamp.
On a side note someone mentioned that heart disease and obesity are also pandemics, could be but I don't think those are contagious, except maybe at Golden Corral.
