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

This document details the WHO and UNICEF estimates for national immunization coverage in France for the 2021 revision, based on data received as of July 7, 2022, with the next revision due July 15, 2023. The estimates are country-specific, reviewed individually without borrowing data from other countries, and aim to assess vaccination performance for specific vaccines and doses.

Methodology for Estimation

• Estimates are generated using data from national reports, surveys, administrative records, and independent denominators (i.e., World Population Prospects).
• A Grade of Confidence (GoC) system is used to reflect empirical support:
  • GoC = No accepted empirical data: Estimates based on extrapolation or lack of supporting data.
  • GoC = Challenged: Data sources contradict the estimate.
  • GoC = Medium/Well-supported: Supported by reported data or surveys, indicating higher confidence.
• Each estimate is subject to potential biases and should be used cautiously, with consideration of the specific context and purpose.

Data Sources

• For post-2010 estimates, data comes from national authorities, surveys, and denominators.
• Pre-2010 data may involve extrapolation or rely on government reports without independent verification.
• Coverage estimates are defined for specific vaccines (e.g., BCG, DTP1/DTP3, Pol3, MCV1/2, RCV1, HepBB/HepB3, Hib3, RotaC, PcV3, and IPV1), and their timing aligns with national schedules and disease epidemiology.

France-Specific Immunization Coverage (Based on Document)

France's immunization coverage is consistently high across most vaccines and time periods, with minimal variation. Notably:

• For DTP1, coverage was around 99% from 2010 to 2021, with some years based on extrapolation.
• DTP3 and Pol3 coverage remained near 96-99% for relevant years.
• Key vaccines like BCG and HepBB showed high coverage in available data.
• GoC was often "Well-supported" (e.g., R+), with specific years like DTP1 2019 having an estimate of 99%.
• No recent independent assessments within five years exist, and higher-quality surveys are recommended for confirmation.
• Full national data and context are summarized in the dataset locations provided.

Limitations and Disclaimers

• Estimates rely on potentially inaccurate or biased data sources and are not adjusted subjectively.
• The GoC does not assess data quality but empirical support levels.
• Use estimates with caution; interpret them based on the objective for which they are being used.
