Overview of dengue vaccination in children and adolescents in the state of Mato Grosso

Abstract

Objective: Describe the panorama of dengue vaccination in children and adolescents in the state of Mato Grosso. Methods: This is an ecological, descriptive, and cross-sectional study that used data from the Ministry of Health, through the Localiza SUS platform, and other sources from the federal government and health institutions, in the year 2024, using the following variables: sex, age, ethnicity, and municipalities of application. Results: Since the beginning of the state vaccination campaign against dengue in 2024, using the Qdenga vaccine, 17,112 doses have been applied to the target audience, represented by individuals aged 10 to 14 years, up to the 35th epidemiological week. However, in the period analyzed, this group's adherence to the complete vaccination schedule was low, with only 17.5% of those vaccinated returning to receive the second dose of the vaccine. Conclusion: The increase in the incidence of the disease, especially in 2024, highlights the need to reinforce control measures. The study reaffirms the use of the vaccine as an important preventive measure available in the SUS, and highlights that it should be widely disseminated in conjunction with health education actions.
