Conclusions
Although it is feasible to use CHWs to obtain accurate population data, it may not be cost-effective to conduct house-to-house registration at full scale since the data obtained was comparable to the district estimates which are based on national census projections. In neglected, hard-to-reach populations and other areas with low immunization coverage, house-to-house registration, and home visits by the CHWs may be useful in addressing the immunization inequities.Facilitating monthly health unit immunization data audit meetings for identifying, tracking, and linking defaulters to immunization services are effective means of increasing immunization coverage and equity and should therefore be considered for integration into immunization programs.
