This study evaluates the temporal distribution of viral respiratory infections and vaccination coverage against influenza and COVID-19 among individuals under 19 years of age in the Federal District, Brazil, during 2024 and 2025. Secondary data were obtained from the Notifiable Diseases Information System (SINAN), the National Immunization Program Information System (SI-PNI), and official epidemiological reports. Reported cases of viral respiratory infections were analyzed and stratified by age group, epidemiological week, and etiological agent, as well as influenza and COVID-19 vaccination coverage by age group. The results indicate distinct seasonal patterns for influenza and COVID-19, with higher incidence among children aged 0 to 4 years. Vaccination coverage showed a decline compared to previous years, particularly among individuals aged 5 to 14 years, suggesting the need to strengthen vaccination campaigns and targeted communication strategies. This study contributes to the understanding of the dynamics of viral respiratory diseases in the post-pandemic context and reinforces the importance of public health policies for prevention.
