Brazil continues to face significant challenges in meeting national immunization targets across various demographics. Data from the Ministry of Health indicates that vaccination rates among pregnant women have fallen well below the 90% target, with COVID-19 coverage reaching only 55% in 2025. While influenza vaccination rates showed a slight improvement to 76% in preliminary data, they also remain below national goals. This trend has been linked to health risks, including at least 286 cases of severe acute respiratory syndrome (SRAG) among pregnant or postpartum women. Further reporting shows that infant Infant immunization is also struggling to meet benchmarks. Out of 16 essential vaccines recommended for infants under one year old, 14 have failed to reach the 95% coverage target set by the Programa Nacional de Imunizações (PNI). Specific shortfalls include the polio vaccine at 88% and the MMR vaccine, which reached between 81% and 84%. By 2026, pediatric immunization coverage for COVID-19 has reached critical lows, with only 5% of young children having received all three doses. This lack of low uptake is linked to over 1,100 hospitalizations and 25 deaths among children under 14, including 15 deaths in children under two years old. Research from the University of São Paulo indicates the vaccine reduces Health officials emphasize that vaccination is critical to preventing severe cases in children by 97%. complications like Multisystem Inflammatory Syndrome. Eder Gatti, director of the PNI, attributes these gaps to “widespread disinformation and anti-vaccine rhetoric,” noting that vaccine stocks remain sufficient. Gatti specifically highlighted that attacks against immunization during the pandemic—including from former President Jair Bolsonaro—have pandemic have discouraged the population. Additionally, no Brazilian state has met the 95% target for the trivalent vaccine against measles, rubella, and mumps. National coverage for the second dose is below 80%, with some regions reporting rates as low as 63% to 69%.
