In this paper, I discuss the bioethical principle of justice and the bioethical key concept of vulnerability, in a queer feminist posthuman framework. I situate these contemplations, philosophical by nature, in the context of antimicrobial resistance (AMR), one the most vicious moral problems of our time. Further, I discuss how gender and sexual variance, vulnerability and justice manifest in AMR. I conclude by considering my queer feminist posthuman framework for vulnerability and justice in relation to the notion of antibiotic vulnerabilities, (...) suggesting a lacuna for further AMR research.
