Governments around the world are testing citizens for coronavirus antibodies, to work out whether people have had the deadly Covid-19 disease.
Some countries are setting up so-called “immunity passports” and others may follow suit.
The idea is that a passport would certify that you have had coronavirus and will not carry or contract the disease again, opening up a way out of lockdown restrictions for the holder.
But is this theory correct? And will it create a group of antibody-carrying elite who can date, travel and work as they wish, while others are still limited by health precautions?

The idea behind immunity passports, is that of a certificate confirming that you have had Covid-19. It could be used to enter places that those people without one are barred from.
To get one, you’d have to test positive for antibodies created after exposure to the virus.
