The approaches regarding the vulnerability of the people involved in the medical act are centered, predominantly, on the patient. The healthcare worker is usually interpreted as a powerful person who has the duty to care and treat. Of course, the patient's illness, his mental sensitivities, the information received from the doctor regarding the state of health can generate various forms of vulnerability. But we cannot overlook the fact that overcoming the vulnerable circumstances of the patient through professional, moral and communication skills of the doctor involved overwork, extended work schedule, obsession with perfection, low resistance to stress, etc., which generates the appearance of Burnout syndrome and affects the person of the doctor, becoming physically, emotionally and cognitively vulnerable. This fact cannot be admitted, because the doctor's vulnerability also influences the quality of medical services. The present communication is focused on two issues: the first involves a synthesis of typologies of human vulnerability to identify particularities in the healthcare worker; the second assumes an ethical approach to these particularities, providing moral conditions for preventing the various contexts that present the doctor as vulnerable.
