There has been plenty of talk about the ethics and practicality of Covid-19 immunity and vaccine passports over the last couple of months, and experts are divided about their introduction.
An immunity passport is an official document for people who previously had Covid-19, which enables them to move around more freely – such as return to work and travel – because they have antibodies. A vaccine passport certifies that a person has been vaccinated against Covid-19.
The introduction of these may reopen the economy and offer a path back to normality. But, proof of immunity may cause people to be less careful about following Covid-19 guidelines, such as physical distancing and mask-wearing.
