This document presents WHO and UNICEF's 2021 revision of immunization coverage estimates for Cameroon, with further data expected from a planned 2022 survey.

Key points:

1. Coverage Indicators: The report covers key vaccines including BCG (Birth Dose,3rd Dose), DTP1, DTP3, Pol3, IPV1, MCV1, MCV2, RCV1 (based on MCV1 estimates), HepBB, HepB3, Hib3, RotaC, and PcV3.

2. Data Methodology and Challenges: Estimates are derived from national reports, surveys, and administrative data, with adjustments made. These data are of varying quality and faces challenges like potential stockouts, under-reporting, and interpretation difficulties. The Grade of Confidence (GoC) reflects empirical support, not data quality. No confidence intervals are provided.

3. Major Concerns Highlighted: Recurrent challenges include stockouts (particularly in 2017-2020), uncertain reporting accuracy, and the reliance on calibrated or survey-modified data due to inconsistent national reporting.

4. Example Data Point: For instance, for Polio coverage (category code Pol3) among infants under 1 year in 2017, the estimate was 77%.

5. Disclaimer: Emphasis is placed on the cautious use of these estimates due to the nature of the underlying data and the absence of formal uncertainty measures.

The report also includes detailed survey data from various years (e.g., Cameroun Enquête Démographique et de Santé 2017, Cameroun Enquête Post-Campagne de Vaccination 2011) used in the estimation process, along with information on previous years available at the linked websites.
