When COVID-19 vaccines are widely available, countries could require travelers be vaccinated before they visit.
The technology for ‘vaccine passports’ has already been created.
The Common Project Foundation has developed one of the apps available, the CommonPass app The nonprofit has partnered with multiple airlines and healthcare providers.
Instead of paperwork that could be faked, the app links to electronic data from a medical provider to verify information. Then it generates a QR code that can be scanned at airports or other venues. The app is already being used as a way to verify COVID-19 test results.
