This study aimed to discuss the morality of public funding for highly expensive orphan drugs for treatment of rare genetic diseases, using tools from bioethics, especially the principle of protection, applicable to vulnerable individuals and populations. Based on this principle, and considering the provisions of the Unified National Health System (SUS), the article argues for the state's moral obligation to provide public policies to ensure care for individuals with genetic diseases like lysosomal storage disorders, who can thus be viewed as "injured", besides suggesting measures to implement and ensure the sustainability of policies with an emphasis on resource allocation, targeting, and equity.
