Throughout the biennium, Brazil maintained a trajectory of recovery in childhood vaccination coverage, with progressive increases and greater homogeneity between states and municipalities. In 2024, the country ceased to be listed among the 20 countries with the highest number of unvaccinated children worldwide.

In addition to pursuing its National Vaccination Movement, in 2024 Brazil introduced a recommendation for a single‑dose HPV vaccination schedule for boys, girls, and adolescents aged 9–14 years, and in 2025 implemented a catch‑up HPV vaccination campaign targeting individuals aged 9–19 years with significant progress. In addition, HPV vaccination in schools was strengthened, achieving coverage levels of 86.04% among girls and 74.40% among boys (2025 data, accessed on 23 March 2026).

PAHO cooperation, in collaboration with the Brazil’s 27 federative units, facilitated the implementation of a microplanning methodology alongside technical and financial coordination. The ImunizaSUS project, led by the National Council of Municipal Health Secretariats, was successfully completed and support was provided through subnational technical cooperation to expand the national information system, ensuring nominal registration of vaccination coverage.

PAHO made a further noteworthy contribution by supporting the self‑assessment and voluntary external evaluation of the 13 management components of the National Immunization Program at the federal level, conducted in 2024 within the framework of the International Health Regulations. The recommendations from this process served as the basis for the development and implementation in 2025 of the plan for strengthening the National Immunization Program. In addition, the process for modernizing the cold-chain network of the Special Indigenous Health Districts in the Northern Region was strengthened in collaboration with the Special Secretariat for Indigenous Health.

PAHO’s contributions to improving vaccination coverage in Brazil were recognized through the award of the Oswaldo Cruz Medal of Merit, Gold Category, in recognition of its contributions to public health in Brazil.
