# Brazil vaccination coverage challenges > Live situation record from CLSTR: https://clstr.news/situations/brazil-vaccination-coverage-challenges > Updated: 2026-10-26T18:40:00.000Z. Sources: 65. Developments: 5. 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. 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%. Despite these gaps, the Sistema Único de Saúde (SUS) distributed over 222 million doses in 2026, and health professionals have launched mobilization campaigns to encourage families to update records. By 2026, pediatric immunization coverage for COVID-19 has reached critical lows, with only 5% of young children having received all three doses. This low uptake is linked to over 1,100 hospitalizations and 25 deaths among children under 14. Eder Gatti, director of the PNI, attributes these gaps to “widespread disinformation and anti-vaccine rhetoric,” noting that vaccine stocks remain sufficient. Additionally, dengue vaccination efforts face hurdles, with more than 3 million adolescents having received only the first dose of a two-dose schedule. While officials state supply is guaranteed, the application of the Butantan Institute’s dengue vaccine remains suspended following reports of severe cases among vaccinated individuals. ## Claims - More than 3 million adolescents have incomplete dengue vaccination schedules.
