The I.A.T.A. (International Air Transport Association) is currently lobbying governments to adopt a digital vaccine passport that can be presented at the border to prove you have the appropriate vaccines, and yes, that includes the COVID-19 vaccine. The hope is to get air travel moving again, especially international travel, not only for the sagging airline industry but the tourism industries of many countries that rely on tourism for a big part of their economy. The concept is a bit complicated so it’s best to have the I.A.T.A. explain it. I hope the idea catches on soon and we, once we are vaccinated, can take to the sky and cross those boarders once again.
