Brazil has implemented various immunization efforts to address diverse public health needs. On National Vaccination Day, the Ministry of Health and the Unified Health System (SUS) coordinated multivacination campaigns across several states to update immunization records for diseases such as measles, polio, and meningitis. Regional efforts included targeted doses for military schools in Aparecida de Goiânia and the deployment of numerous vaccination points in Campina Grande.

Following these broad campaigns, health authorities issued specific calls for the second dose of the dengue vaccine for individuals aged 4 to 59. This targeted mobilization aims to ensure a complete immune response against all four virus serotypes, amid projections from InfoDengue/Fiocruz suggesting Brazil could reach approximately 1.7 million dengue cases by 2027.
