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

WHO and UNICEF provide country-specific estimates for vaccines such as BCG, DTP1, DTP3, Pol3, IPV1, MCV1, MCV2, RCV1, HepBB, HepB3, Hib3, RotaC, and PcV3, based on administrative data, surveys, and interpolation. Data quality varies, with COVID-19 significantly impacting coverage in 2020 and 2021 due to health system strain, leading to unexplained declines. Covers 2010-2021; estimates are not guaranteed accurate, graded by confidence levels (GoC). Declines in certain vaccines like BCG and IPV1 highlight data reliability issues, with ongoing efforts to improve data quality.

Key Findings:

• Overall, immunization coverage fluctuates; notable drops occurred in COVID-19-affected years (2020-2021), e.g., BCG coverage fell to 61% in 2021.
• Vaccines like HepBB had high estimates but faced data challenges, while others like DTP1 showed partial explanations for declines via target population changes.
• The 2019 survey suggested lower coverage for some vaccines compared to administrative data, indicating reliance on multiple sources.

Recommendations: Use estimates cautiously as data uncertainty persists, especially post-COVID, to avoid misinterpretation in public health planning.

Data Sources: Includes national reports, surveys, and interpolated data; grade of confidence (GoC) reflects empirical support, but no formal uncertainty intervals provided. Full details available via WHO and UNICEF data portals.
