Sao Paulo Seeks Under-Vaccinated Children to Reduce Dengue Outbreak

Throughout the Region of the Americas, the Federative Republic of Brazi has been the unfortunate leader in the multi-year Dengue fever outbreak.

In Brazil, the Municipal Health Department of São Paulo reported the most Dengue cases in 2024, about 2.1 million. 

To reduce the number of pediatric Dengue cases in 2025, the Municipal Health Department of the capital advised parents and guardians on February 7, 2025, to take children aged 10 to 14 for Dengue vaccination, which occurs at Basic Health Units (UBSs).

UBSs also actively searched the territories in 2024 and 2025 to ensure that Dengue immunization reached this population. The government has estimated 600,000 children in Sao Paulo, and 259,000 first doses (38%) and 134,000 second doses (20%) have been administered to date.

As of February 12, 2025, Takeda's QDENGA® two-dose vaccine is available in Brazil and the Americas but not in the United States.
