Information about factors associated with immunization in children with congenital heart disease is lacking. Objective: To determine factors associated with the basic immunization in children with congenital heart disease. Methods: This is a sequence explanatory mixed method study which combined quantitative analytic study on 90 subjects and qualitative study using focus group discussion. Parents of children with congenital heart disease aged 12-60 months who posses immunization card were included. Independent variables were mother's age, education, occupation, child's age at diagnosis, congenital heart disease type, information and source of information, knowledge and attitude, while basic immunization status served as dependent variable. Outcome of quantitative study was used as initial topics discussed at the focus group discussion. Results: The percentage of fully immunized children in this study was 83.3%. Knowledge and information have significant association with basic immunization status. Counseling by health workers and the information about vaccines' safety gave confidence to participants of focus group discussion to provide immunizations. The biggest concern came from midwives who worried about the children's condition so they refused to give the immunization. Conclusion: Knowledge and information are factors associated with basic immunization status in children with congenital heart disease. Midwives concern about children condition made them refuse to give the immunization. It is necessary to provide councelling for midwives about immunization in children with congenital heart disease.
