WHO and UNICEF's 2021 revision of immunization coverage estimates for Brazil spans from 2010 to 2021, based on data submitted by national authorities and other sources. Key vaccines include BCG, DTP1/DTP3, Pol3, IPV1, MCV1/2, Rubella-containing vaccine (RCV1), HepB birth dose (HepBB) and third dose (HepB3), Hib3, RotaC, Pneumococcal conjugate vaccine (PcV3), and Yellow Fever vaccine (YFV). Estimates rely on reported data, administrative records, surveys, and calibration methods, with grades of confidence (GoC) indicating data support. The COVID-19 pandemic in 2020 correlated with a 20% decline in childhood vaccinations, though some recoveries were noted, and records show vaccine stockouts affecting coverage. All estimates carry uncertainties due to potential biases and lack of granular data, such as survey availability or subnational coverage details. These figures should be used cautiously and assessed per use case. Further details and earlier data are available at specified WHO and UNICEF websites, with the next revision due July 15, 2023.
