I’m not sure why all the protests are going on these days against creating vaccine passports. The CDC vaccination card is now being used as exactly that — even though it’s not a verifiable document and if I recall correctly from last year, the CDC and other sources said that they had no plans for a vaccine passport.
I had to show mine Wednesday to see a Portland Thorns soccer match – required as the first step to even be able to enter the stadium, or you had to show a negative PCR test.
And I checked with Ukraine – it’s acceptable as proof of vaccination for a border crossing.
I sent a photo of my vaccination card, with my hand-written name, to visitukraine.today to check, and received the response
Yes, this type of certificate is acceptable
So that little card, just handwritten and maybe stamped, officially created as a reminder for your second shot, is now acceptable nationally and internationally as a vaccine passport.
