Covid-19 research with humans in Brazil

Abstract The Covid-19 pandemic challenges research institutions with the urgent need of responding to the morbidity and mortality caused by the virus. This study aimed to overview studies with humans on this disease in the first three months of 2020, in Brazil. Official data of the population and research protocols on Covid-19, distributed by Brazilian states, supported this temporal analysis. The incidence of the virus has grown exponentially, especially in the North and Northeast regions. Despite the discrete, slow, and asymmetric diffusion of studies, they are concentrated in the Southeast, and few clinical trials have entered Phase II. The geographical distribution of research ethics committees, higher education institutions, investments in science and technology, health centers and hospitals generate state vulnerabilities when addressing the disease. Close longitudinal follow-up should be carried out in the face of regional inequities, to defend bioethical principles and human life.
