Vulnerability has been extensively discussed in medical research, but less so in health care. Thus, who the vulnerable in this domain are still remains an open question. One difficulty in their identification is due to the general criticism that vulnerability is not a property of only some, but rather of everyone. By presenting a philosophical analysis of the conditions of vulnerability ascription, we show that these seemingly irreconcilable understandings of vulnerability are not contradictory. Rather, they are interdependent: they refer to the same concept with different likelihoods of manifestation. We argue that the general vulnerability of living beings relies on their having certain types of interests. In health care, those individuals are particularly vulnerable who are more likely to have these interests unjustly considered. They should be afforded special protection in order to receive what is due to everyone, but which they are likely to fail to receive.

In the literature on medical ethics, it is generally admitted that vulnerable persons or groups deserve special attention, care or protection. One can define vulnerable persons as those having a greater likelihood of being wronged – that is, of being denied adequate satisfaction of certain legitimate claims. The conjunction of these two points entails what we call the Special Protection Thesis. It asserts that persons with a greater likelihood of being denied adequate satisfaction of their legitimate claims deserve special attention, care or protection. Such a thesis remains vague, however, as long as we do not know what legitimate claims are. This article aims at dispelling this vagueness by exploring what claims we have in relation to health care – thus fleshing out a claim-based conception of vulnerability. We argue that the Special Protection Thesis must be enriched as follows: If individual or group X has a greater likelihood of being denied adequate satisfaction of some of their legitimate claims to physical integrity, autonomy, freedom, social provision, impartial quality of government, social bases of self-respect or communal belonging, then X deserves special attention, care or protection. With this improved understanding of vulnerability, vulnerability talk in healthcare ethics can escape vagueness and serve as an adequate basis for practice
