A Total of 227 children aged 12 to 23 months who already got immunization of hepatitis B zero dose and well documented were included as samples in this study. Timely immunization was defined based on the distance between time of birth and time of received hepatitis B immunization (zero dose) that is within 24 hours after birth. Data was analyzed using Chi-square and Logistic regression in multivariate level. The result of this study showed only 60.4% of children were get timely hepatitis B zero dose immunization. Mother’s behavior agains immunization program is the only factor that can predict the timely hepatitis B zero dose immunization (P-value 0.007 CI 95% 1.94-3.62). Meanwhile, other factors i.e. sex, socio-economic status, parent’s education, knowledge and attitude of mother and place of immunization service have not able to predict the outcome, statistically.
