Germany's immunization coverage estimates, as reported by WHO and UNICEF for the 2021 revision (data received as of July 7, 2022), are detailed statistical assessments of vaccine coverage from 2010 to 2021. The methodology relies on multiple data sources, including school-entry examinations, administrative records, survey-based estimates, and independent denominator calculations, with a grade of confidence (GoC) assigned to indicate empirical support and potential uncertainties.

• Key Findings by Year and Vaccine:
  • BCG: No reliable estimates available for most years.
  • DTP1 and DTP3: Coverage has been consistently above 98% since 2010, based on school-entry data validation.
  • IPV1, MCV1, MCV2, RCV1: High coverage (>95% since 2011), with estimates assigned by working groups where direct data is lacking, showing stability.
  • Pol3 and HepB3: Coverage for polio-related vaccines is ~91-96%, with notes of possible underestimation due to data extrapolation.
  • Hib3, RotaC, PcV3: High coverage (>82%) from 2011-2021, with methodological qualifiers emphasizing data interpolation or challenges from source reliability.
  • COVID-19 Impact: Data for 2020-2021 shows reduced examination coverage, potentially affecting accuracy.

The estimates range from high confidence (GoC=•••) to low confidence (GoC=•), with italic* analyses note**

• Data sources include reported data (R), denominator adjustments (D), and surveys (S).
• Coverage is often extrapolated for birth cohorts, highlighting uncertainties.
• Data reliability is altitude-dependent, with COVID-19 causing gaps.

Overall, most vaccines show robust coverage since the late 2000s, but continuous monitoring is advised due to data limitations and the potential for misinterpretation.
