Vaccination card loss and associated factors in Ethiopia: A multilevel analysis using Ethiopia Mini Demographic and Health Survey 2019 data.

Background: The loss of vaccination cards is a momentous public health challenge in the prevention of vaccine-preventable diseases in most developing countries. There is a paucity of studies on the magnitude of vaccination card losses and associated factors in Ethiopia. Therefore, the aim of the current study was to assess the level of vaccination card loss and associated factors in Ethiopia.

Methods: Data were extracted from the 2019 Ethiopia Mini Demographic and Health Survey, a nationally representative household survey of women aged 15-49 years with children aged 0-35 months. Data from a total of 3208 mother-child pairs was extracted for the study. A multilevel logistic regression model with random effect analysis techniques was used to identify individual and regional-level determinants of vaccination card loss. We checked the model's fitness by using Akaike Information Criteria and Bayesian Information Criteria. Odds ratios with a 95% Confidence intervals were used to declare statistical significance.

Results: A total of 3208 mother-child pairs from nine regions and two city administrations were included in the analysis. The result revealed that 1933 (60.26%) mother-child pairs did not have vaccination cards during home visits. illiterate mother 2.239 (95% CI: 1.297, 3.864), lowest wealth index category 2.089 (95% CI: 1.432, 3.048), ANC non-user 2.047 (95% CI: 1.605, 2.609), children living with their caretaker 6.749 (95% CI: 1.425, 13.654), having no access to television 1.384 (95% CI: 1.150, 1.664), longer birth interval 1.325 (95% CI: 1.027,1.710), giving birth at home and private health facilities 1.985 (95% CI: 1.579, 2.497), 1.696 (1.086, 2.648), contraceptive non-users 1.295 (95% CI: (1.042,1.609) and children aged 12-23 months and 24-35 months 1.577 (95% CI: 1.252, 1.985) and 2.282 (1.803, 2.889) were associated with vaccination card loss.

Conclusions: Overall vaccination card loss among mothers of 0-35-month-old children is considerably high. To enhance maternal awareness regarding the significance of vaccination cards, promote antenatal care and public health facility delivery, and future researchers have to explore how to enhance vaccination card retention in Ethiopia.
