Given the incredible harm caused by COVID-19 over the last year or so, increasing evidence for the tremendous success of vaccines in preventing deaths and mitigating the severest effects of the disease, the safety of vaccines, and the equal opportunity to receive a vaccine (certainly in the UK), it would be very hard to argue against the vaccine passport concept from a veil of ignorance position.
Of course, the devil is almost always in the detail. A poorly implemented vaccine passport system could still be very unfair and cause tremendous unforeseen and undesirable circumstances. Currently, there are a number of concerns relating to the recognition of different types, and even different batches, of COVID-19 vaccines. But overall it is important to distinguish between arguments about fair implementation and arguments that concern the fairness of the concept as a whole.
