Background: Vaccination is one of the most cost-effective interventions to preventrnmajor illnesses that contribute to child mortality in the country, particularly inrnenvironments where malnourished children, overcrowding, poverty and illiteracy regionrn(2).despite the fact that the vaccination service is free in Ethiopia, the vaccinationrncoverage is very low among the lower economic class. However, there are limited studiesrnamong children born from vulenrable population especially among street women.rnTherefore, this study aimed finding out & describing the vaccination status of streetrnchildren in the Ethiopian context. The survey result will serve as worthy data as arnbaseline.rnObjectives: To assess vaccination status and its associated factors among 6-23 months rnage children born from women at the street and currently living at the streets of AddisrnAbaba, Ethiopia.rnMethod: A community-based cross sectional study was conducted from August 2019 tornSeptember 2019 in three Sub cites; Addis ketema, Kirkos & Arada which was selectedrnfrom Addis Ababa by using simple random sampling method and the total 392 studyrnparticipants were selected from each sub city by using proportionated to number ofrnchildren and simple random sampling method. Data were entered cleaned and analyzedrnusing SPSS version 22.rnResult: A review of the vaccination cards and maternal recall children indicated that rn38.04% of 6-23 months old street children living around Addis Ababa in the selected Subrncities were fully vaccinated. 95.7% were ever vaccinated, 65.2% vaccinated for age &rn4.3% unvaccinated. From the total, BCG is in general the most taken by the majority ofrnchildren (95.7%) followed by polio1 (94.4%) penta 1 (92.1%), measles was the leastrntaken vaccine type which was 44.96%. The coverage showed a decrement from the firstrndoses of vaccine to the last doses. Maternal age less than 20 year were more likelyrnpracticing child vaccination AOR= 0.6 (CI= 0.2, 0.8) compared to maternal age greaterrnor equal to 31 years. Maternal literacy (AOR = 1.5(CI= 1.05, 2.4), daily income (AOR =rn1.9(CI = 1.13, 4.6) were found to be factors significantly associated with fullrnimmunization in the logistic regression analysis. rnConclusion: There is low immunization coverage among children aged 6-23 months inrnthe study Sub cities. Age of mother & knowledge of mother & institutional delivery isrnsignificant predictor of child vaccination status. The Addis Ababa health bureau, Subrncities, woredas and Health centers especially live around street children concentratedrnareas should work to raise awareness of street living community on vaccination andrnvaccine preventable diseases.
