The Lemann Graduate Fellowship allowed me to focus on my M.A. thesis and graduate courses for my entire academic year. My project started with a curiosity about the effects of health emergencies on our society and how politics can impact the health field. In the summer of 2022, I visited the Brazilian Ministry of Health archives. I found advertising material for HIV/AIDS public health campaigns. The posters were intriguing, and the differences among them helped me to choose them as the primary source of my research. I saw those pieces as a message from their creators and a result of the domestic and international political context. My mission was then to organize the timeline to understand who were the poster children of each period, the persons depicted, and the main target of the campaigns. I focused on three decades when Brazil had six presidents from different points on the political spectrum. By visualizing health campaign posters, I could understand which groups were prioritized, who was concerned about them, and what sort of diversity they contained. I observed how groups were incorporated into the posters according to the political will of their creators. These posters are representative of the intersectionality of their period because, through them, it is possible to visualize race, gender, age, and class. The construction of the public changes and the agency of civil society organizations. This work highlights the impacts of political will in the health field and the significant role of NGOs and civil society movements. In November 2022, I presented my early findings with a poster at the Lemann Center for Brazilian Studies Graduate Forum. Currently, I am finishing my master’s thesis, hoping that my work will contribute to a better understanding of Brazilian society.
