Determinants of default from completion of child immunization among children aged 15-23 months in Kacha Bira district, Kembata Tembaro zone, South Ethiopia: a case-control study.

Background: Child immunization is crucial to protect children from vaccine-preventable diseases. However, if a child defaults from completing immunization, they are at a greater risk of contracting such diseases. Previous studies have evaluated various factors that contribute to defaulting from immunization, but they did not consider the fear of COVID-19 as a variable.
