In the face of healthcare emergency and the linked problems, the purpose of the work is to identify an economic and organizational tool for the improvement of the person's health condition and, consequently, for the prevention of the spread of future contingent pandemics. Due to the lack of public resources, this system would contemplate private investments balancing social and speculative objectives. It analysed the social impact bond (SIB), the typical form of impact investing that provides for public and private partnership. After examining the structure with its positive and negative aspects, the disintermediation through blockchain technology and smart contracts is prospected. According to the horizontal subsidiarity, stated in the article 118, paragraph 4, Cost., the suggested intervention would represent an operation aimed at realizing the right to health through a negotial tool (the SIB agreement) subject to the control of merit.
