Background: In 1974, the World Health Organization (WHO) launched the Expanded Pro­gram on Immunization (EPI) initiative. In 2013, an estimated 14% of the infants (mostly from low income countries) failed to access three of these vaccines (DPT) du­ring their first year of life. The purpose of this study was to examine factors asso­ciated with DPT vaccine completeness among infants in Wonogiri, Central Java.

Subjects and Method: A cross sectional study was conducted in community health cen­ter II, Wonogiri, East Java, from October to December 2018. A sample of 200 in­fants was selectedbysimple random sampling. The dependent variable was DPT vac­cine completeness. The inde­pen­dent variables were intention, attitude, knowledge, per­cei­ved behavior control, subjective norm, education, employment, family income, reli­gion and belief, family support, health personnel support, and exposure to information. Data on DPT vaccine was obtained from medical record. The other data were collected by questionnaire and analyzed by path analysis.

Results: DPT vaccine completenessdirectly increased by intention (b= 1.99; 95% CI= 1.16 to 2.82; p<0.001), attitude (b= 1.00; 95% CI= 0.16 to 1.84; p= 0.020), and family sup­port (b= 1.07; 95% CI= 0.23 to 1.91; p= 0.013). It was indirectly affected by mater­nal knowledge, education, attitude, employment, family income, religion and belief, ex­po­sure to information, health per­son­nel support, perceived behavior control, and sub­jective norm.

Conclusion: DPT vaccine completenessdirectly increases by intention, attitude, and fami­ly sup­port. It is indirectly affected by maternal knowledge, education, attitude, em­ploy­ment, fa­mily income, religion and belief, exposure to information, health personnel sup­port, perceived be­havior control, and subjective norm. Theory of Planned Behavior can be used to explain pre­dictors of DPT vaccine completeness.
