Context: The right to health in Brazil, enshrined in Article 196 of the Federal Constitution, requires the integration of scientific knowledge with distributive justice. Epidemiology and the social determinants of health (SDH) show that illness results from structural inequalities rather than merely individual biological risks. However, the design and assessment of public policies still rely on fragmented rationalities in which empirical evidence and legal norms operate separately. Problem: The dissociation between the empirical rationality of epidemiology and the deductive rationality of Law has limited the effectiveness of health policies and the realization of equity. A method capable of translating social evidence into measurable legal obligations is lacking, rendering SDH invisible in decision-making processes. Objectives: To analyze how the integration between epidemiological evidence and legal normativity can serve as a criterion for health justice and for assessing the effectiveness of the right to health, based on the Federal Constitution, Law No. 8.080/1990, and key WHO and CNDSS documents. Methods: A qualitative and descriptive approach was adopted, with bibliographic and documentary analysis of legal norms, technical reports, and national and international scientific literature produced between 1990 and 2025, including works by Krieger, Marmot, and Nunes. Results: A persistent gap between evidence and juridicity was identified. Epidemiology is legally recognized as a principle of the Brazilian Unified Health System (SUS) but rarely informs administrative or judicial decisions. SDH remain marginalized, even though they constitute indicators of non-compliance with constitutional duties. Conclusions: The effectiveness of the right to health depends on the convergence between empirical and normative reasoning. Integrating epidemiology into the legal framework of public policies is essential to transform data on inequality into parameters of equity, allowing scientific evidence to regain its ethical and political role as the foundation of health justice.
