Immunity passports could help end lockdown, but risk class divides and intentional infections

If you’ve already recovered from the coronavirus, can you go back to the workplace carefree? This is the question governments including in the UK, Chile, Germany and Italy are trying to answer by considering immunity passports. These would be physical or digital documents given to people who’ve recovered from COVID-19 and are immune from the disease for a period of time. This would enable them to return to the workplace or even travel. But there are serious concerns that immunity passports could create two classes of citizen and provide a perverse incentive to contract the virus deliberately.
