Risk factors associated with zero-dose and under-immunized children, and the number of vaccination doses received by children in Ethiopia: a negative binomial regression analysis

Our study highlighted individual and community-level factors associated with the number of vaccination doses children received in Ethiopia. To address zero-dose and under-immunized children in Ethiopia, contextualized intervention focusing on the pastoral and vulnerable population is needed. Moreover, strengthening the health system and expanding healthcare access in the underserved population could help improve child vaccination.
