Re: Will vaccine passports lead to the demise of vaccines?
Ah, that reminded me of good old days of working in Africa and having one of these (well they were different those days, no QR codes etc LOL) for my travels. If I go through piles of my old papers I might find it, blow the dust off and use it for brand new Covid stamp 
My first booklet is a pale pink colour because the ((as it turns out) unregistered) nurse in the first aid room at my work place thought it'd be a great idea for the booklets to be pink when she was ordering them... It wasn't until I went to a travel doctor that I was given a correct colour booklet. Now I've got three mostly full booklets and have turned up at pharmacies here in Oz and a GP's and a pharmacy in NZ and gotten various jabs (pneumonia, flu, tetanus etc) and none blink when I hand over the booklet, they just add the relevant information and sign.
Like the jabs themselves, very quick, very easy and very convenient to carry with you when traveling.
