Showing the "V"

Hidden deep within a wide-ranging news roundup post, is this interesting tidbit:

The boss of Australia's Qantas airline, Alan Joyce, on Tuesday said proof of vaccination will likely become the only way people will be allowed to fly.

Coincidentally, I was thinking about the new world the other day, and I found myself imagining little stickers, round, maybe an inch across, with a gold "V" on a red background.  Just like the "I voted" stickers.  

Somehow, we'll need to be able to prove, quickly and easily, that we have, in fact, been vaccinated.

Mr. Joyce won't let us on his airplanes if we can't do this.  What else will depend on the "V"?  And how will we prove it?

Let's assume for a moment that vaccination will ensure that we won't get the virus and that we won't give the virus to anyone else.  For a start, that means we won't need to wear a mask.  Which means that the "V", whatever it is, should not be something we have to dig out of our wallet, or look up on our phone.  It will mean that we can eat or drink in a restaurant or bar, and we can go to the movies as long as everyone we pack into the theater with also has a "V".  We can go to work, and go to school.  If 70% of us have our "V", we have herd immunity, which sounds great but won't work out so simply in the real world.

Will the elderly or medically fragile among us be allowed to check for the "V" before entering a class, or a meeting, or an office, or a restaurant?  Will there emerge cultural distinctions, or even prejudices, regarding "V"s and non-"V"s?  

For a brief moment I thought about a tattoo, maybe on the palm.  The forehead?  Probably not.  What else?  How will prove we're "V"-ed?  

And for how long?  How long will it be important to distinguish between those of us who have been vaccinated, and those of us who haven't?   

The new world just got a little more interesting.
