Vaccination certificates expected to play key role
With COVID-19 vaccination programs gaining pace worldwide, governments are considering options to reopen borders and resume international travel－an industry that lost income of almost $4.5 trillion globally last year due to the pandemic.
In March, China announced the release of an international travel health certificate, which could potentially allow people who have been vaccinated to sidestep quarantine rules.
The European Union has proposed a Digital Green Certificate to allow free movement between member states and other countries, hoping for a launch sometime in June.
