Certain businesses (i.e. cruises/travel) are requiring the cards for COVID-19 vaccinations. Worth holding on to the card, if they give you one.

During my vaccine, they very specifically said not to lose the card, and keep it somewhere safe. Although our cards were different, they're just as flimsy. I wonder if people are forging these cards already? It really wouldn't surprise me.

I'd imagine forgery wouldn't jeopardize anyone (except the person doing it), given most of these businesses are only allowing card-carriers - who are pretty much immune.
