Despite a months-long vaccination campaign, the Federal District in Brazil has fallen significantly short of its target to immunize 90% of children and adolescents aged 10 to 14 against dengue. Current statistics reveal that only 41.9% of the target group has received their first dose, while a mere 16% are fully vaccinated with both doses required for comprehensive protection. This shortfall raises concerns about the region's preparedness against potential outbreaks in the future.

The dengue vaccine, Qdenga, has been approved by Brazil's health regulatory agency for individuals aged 4 to 60. However, in the Federal District, free vaccination is available only for young people aged 10 to 14, forcing those outside this age range to rely on private healthcare systems to receive the vaccine. This limited access could exacerbate public health issues and complicate efforts to mitigate dengue infection rates across wider demographics.

Juliane Malta, the director of Epidemiological Surveillance at the Health Department, emphasized that even with a decrease in dengue cases, the threat of new epidemics looms large. The significance of reaching vaccination targets cannot be understated, as public health leaders strive to contain the mosquito-borne virus while ensuring that the population is adequately protected against future outbreaks.
