Despite the availability of safe vaccines against SARS-CoV-2, some people will remain vulnerable because they will not be vaccinated. Who are these non-vaccinated people? We can distinguish two groups: (i) persons who cannot be vaccinated for clinical reasons and who, despite having been vaccinated, have not achieved immunity; (ii) persons who voluntarily refuse to get vaccinated. These groups have in common an immune system that will make them vulnerable to COVID-19. The reasons for their vulnerability and the ethical judgment they (...) deserve are different; the solutions offered to them are also different. In the case of those who voluntarily avoid vaccination, States are not compromised to introduce new protective policies. In the case of people who remain involuntarily vulnerable, instead, the response should be articulated on the same rules and principles that inform the social model of disability because they will live with an organic disability.
