Greece and Austria are encouraging the European Union to implement vaccination ‘passports’ to support the struggling tourist industry.
Austrian Chancellor Sebastian Kurz tweeted out "we're advocating a digital Green Pass, like Israel's".
"That should allow you to prove, on your mobile phone, that you've been tested, inoculated or have recovered. Our goal: to avoid a lengthy lockdown and finally enable freedom to travel again in the EU, and freedom to enjoy events and cuisine."
The proposition faces opposition from other nation-states, including France and Germany who are concerned it’s too early to implement vaccine passports while vaccine efficiency data is still being collected.
