This policy perspective highlights how the 2025 BRICS chairship, under Brazil’s leadership, advanced a collective health agenda rooted in equity, innovation, and solidarity among Global South nations. Through the XV BRICS Health Ministers’ Meeting (Brasília, 17 June 2025), members prioritized cooperation on tuberculosis, regulatory convergence, digital health, and the elimination of socially determined diseases. These efforts reaffirmed health as a strategic pillar for multilateral renewal. Among the major outcomes, the bloc launched the Partnership for the Elimination of Socially Determined Diseases, the Network of National Public Health Institutes, and progress on regulatory harmonization and artificial intelligence and health data governance. Together, these initiatives created operational frameworks to expand access, strengthen research collaboration, and build technological sovereignty. Brazil’s domestic achievements – such as World Health Organization’s 2024 certification of lymphatic filariasis elimination and the nationwide digital transformation through the SUS Digital Program and the National Health Data Network – reflect how national progress can reinforce collective goals. By translating shared political will into practical cooperation, BRICS demonstrates that South–South collaboration can deliver measurable results. These advances position the bloc as a driving force for inclusive global health governance and a model for how emerging economies can advance universal health coverage and health for all on a planetary scale
