Abstract

Several countries have implemented COVID passports or health certificates to promote a safer return to in-person social activities. These certificates have been proposed as a way for people to prove that they have been vaccinated, that they have recovered from the disease, or that they have negative results on a diagnostic test. However, many people have questioned its ethical justification. This article presents some practical and ethical problems to consider if we want to implement these passports. Among the former, it is discussed how accurate diagnostic tests are to ensure that a person is not contagious; whether vaccination guarantees immunity; what are the levels of immunity after infection, vaccination and protection against variants; the fact that passports can be forged; if they encourage vaccination and the problem that there is no universally recognized passport. Among the ethical issues it is discussed whether passports promote discrimination and inequality, and whether they violate the rights to privacy and freedom. It is concluded that passports have enough ethical justification to be implemented.
