In light of recent efforts by the UN to more firmly embed SSC and TrC in all its institutions, this paper examines the challenges that lie ahead by first tracing the emergence of the terms SSC and TrC on a discursive level in the UN system. Second, it reflects theoretically on the concepts of solidarity and development to show that voices from the Global South are suggesting alternative understandings that may do more justice to the poor and disadvantaged. Third, it explores what can be learned from various interlinked health crises and the recent COVID-19 pandemic regarding the flaws of SSC and TrC. Fourth, it sketches a way forward by looking at ways in  which a more human rights based democratization of global health can be achieved.
