Summary of WHO and UNICEF Immunization Coverage Estimates for Australia (2021 Revision)

Background: WHO and UNICEF estimate national immunization coverage based on country-specific data, considering various sources like administrative records, surveys, and empirical data with potential biases. No data borrowing from other countries occurs.
Methodology: Estimates are derived from reported data, and grades of confidence (GoC—•••, ••, or •) reflect empirical support, not data quality. GoC••• indicates strong support with independent denominators and supporting surveys, GoC•• indicates at least one supporting source, and GoC• suggests limited or challenged data. Classical uncertainty measures (e.g., confidence intervals) are not provided.
Australia-Specific Context: Data includes coverage estimates from 2010 to 2021 for vaccines such as BCG, DTP1, DTP3, Pol3, IPV1, MCV1, MCV2, RCV1, HepBB, HepB3, Hib3, RotaC, and PcV3. Coverage is primarily based on national government reports and, for many years, the Australian Immunization Register (which may slightly underestimates coverage in some cases). High coverage levels are observed across most vaccines in recent years, with averages ranging from 91% to 98%. Changes in some estimates (e.g., RCV1, HepB3) reflect data interpolation or adjustments.
Grades of Confidence: Most estimates show a •• or ••• GoC due to reported data support and calculations with UN Population Division denominators. For instance, DTP3 estimates in 2018-2021 have GoC••, indicating support from government data.
Data Quality and Limitations: Estimates should be used with caution due to varying data quality, potential underestimation by the Australian Immunization Register, and lack of universal supporting surveys. No significant trends to low coverage are observed in the reported period.
