Here's a suggestion for those out there who have now received both doses, or the single dose J & J vaccine. Photograph your 'COVID-19 Vaccination Record Card' to your cell phone rather than carrying the card around with you so you'll have a back-up. This may come in handy for future travel, especially if the development of a COVID Vaccination Passport never comes to fruition. As Scubaman noted in a recent post vaccination passports may be forthcoming later this year, but I'm not going to hold my breath waiting for this. Hopefully, proof of COVID vaccination will be an acceptable alternative to a negative COVID test around the world.
