Ecuador's immunization coverage estimates for 2021-2022 were assessed by WHO and UNICEF. Key points include:

• Disruptions: Coverage declined significantly in 2020 (attributed to COVID-19 service disruptions) and remained low in 2021.
• Stock-outs: Multiple vaccines (e.g., DTP, MCV1, IPV) reported stock-outs in 2020-2021, impacting coverage.
• Data Gaps: No nationally representative surveys since 2012, raising concerns about data accuracy; high-quality surveys recommended.
• Fluctuations: Coverage varied across vaccines. For instance:
  • BCG (98% in 2021, down from peaks)
  • DTP1/DTP3 showed declines in 2019-2020, with concerns of overestimation.
  • Pol3 (polio) coverage dropped but remained relatively stable post-2020.
  • IPV1 was new in 2015, with variable results, likely due to using fractional doses.
  • MCV1/RCV1 had concerns due to discrepancies with routine administration schedules and potential data overestimation.
• GoC: Coverage levels are based on administrative or survey data (R+ D+ confidence), calibrated to avoid exceeding 100%. Some years were challenged (GoC D-, R-) due to data uncertainties or inconsistencies with earlier estimates.
• Recommendations: Urgent need for national surveys to validate reported coverage levels.

Overall, Ecuador's immunization coverage faces challenges, especially around the peak years 2020, but remains relatively high for some vaccines post-revision.
