^*Data analysis was performed using un-paired t test. ^# Data analysis was performed using one-way-ANOVA followed by the Tukey post-test. ^$indicate significant difference from other categories (i.e., mothers who vaccinated their children at private clinics or hospitals had significantly higher knowledge score compared with those who vaccinated their children at public health centers and government hospitals, or maternity/childhood centers. Additionally, mothers who got the information about vaccination from medical staff had significantly higher knowledge score than those who got information from TV-radio-Internet, health center posters/brochures, and/or family members, friends, and neighbors)
