Dissertação (Mestrado Profissional em Desenvolvimento Regional) - Centro Universitário Alves Faria, 2026.http://repositorio.unialfa.com.br/handle/123456789/831This research investigates the role of the Government of Goiás' institutional communication as a key element in the success of the dengue vaccination campaign in the Metropolitan Region of Goiânia between 2024 and 2025. Through a qualitative and documentary approach, the study analyzes how the clarity and transparency of official messages not only informed but also mobilized society during a critical public health moment. Based on theories of public communication and regional development, the work introduces the concept of "social vaccine": the idea that well-transmitted information can immunize the population against misinformation and strengthen trust in institutions. The results indicate that the multichannel strategy and active listening on social media were decisive in achieving 78.6% vaccination coverage, generating benefits that transcend health, such as strengthening social capital and integration among the municipalities of Greater Goiânia.ptComunicação institucional governamentalDengueVacina socialPolíticas públicas de saúde
