Abstract
BACKGROUND: Vaccination has saved millions of lives. However, the vaccination rate in Nigeria remains low. We differentiate reasons for incomplete vaccination by status: not- and partially- vaccinated, and examine the association between sociodemographic characteristics of caregivers and reasons for incomplete vaccination. METHODS: Data from the Multiple Indicator Cluster Survey (MICS) conducted in Nigeria in 2016 and 2017 was analyzed. The logistic regression was used to evaluate associations between sociodemographic characteristics of caregivers and incomplete vaccination according to different reasons. RESULTS: The most common reason for non-vaccination is that caregivers have no faith in immunization (27.0%), followed by lack of awareness of the need for immunization (26.0%) and the perception that the place where immunization is given is too far/inconvenient (24.3%). The most common reason for partial vaccination is that caregivers thought the children had already been fully immunized (44.8%), followed by the inconvenient location for immunization (15.3%) and supply-side issues such as shortage of vaccine stock and absence of vaccinators (14.4%). Among caregivers whose children are never vaccinated, a lower level of education is correlated with more likelihood of having no faith in immunization and poorer households are more likely to state a lack of awareness of the need for immunization need and an inconvenient place as the reasons for non-vaccination. Among caregivers whose children are only partially vaccinated, educated and wealthier caregivers are more likely to state that they thought their children were fully vaccinated, while poorer caregivers tend to give an inconvenient immunization place as the reason for incomplete vaccination. Supply-side barriers are not systematically correlated with educational attainment or wealth level of caregivers. CONCLUSION: Barriers to vaccination are different according to vaccination status: not- and partially- vaccinated, as is the association between sociodemographic characteristics of caregivers and reasons for incomplete vaccination. The policy to increase vaccination take-up should take these differentials into consideration.
