Vaccine Passports

US rules out vaccine passports

Schemes to introduce such passports have been touted around the world as a way to enable safe circulation of people while fighting the pandemic.

America has lost more than half a million lives to the virus.

Nearly 31 million cases have been registered, making the US the country worst affected by the pandemic, figures from Johns Hopkins University indicate.
