Vaccination coverage and factors associated with incomplete childhood vaccination among children aged 12-59 months in Miagao, Iloilo, Philippines

Abstract

Background: Complete Vaccination has made a significant contribution to the prevention of infectious diseases among children. However, not all children were completely vaccinated. This study aimed to determine the vaccination coverage, timeliness, and maternal-related factors associated with incomplete vaccination of children in Miagao, Iloilo, Philippines.Methods: A cross-sectional study of children aged 12-59 months at the time the study was conducted between April 15 and 26, 2019 in Miagao, Iloilo. A total of 515 children were selected using a two-stage random sampling design. The data were collected from the Target Client Lists records, encoded, and analyzed using SPSS v21. Binary logistic regression was used to determine the factors associated with incomplete vaccination. Crude and adjusted odds ratio (AOR) with their confidence interval were reported.Results: The complete vaccination coverage among children was low at 28.7%. Among those completely vaccinated, 2.7% to 88.5% had untimely Vaccination. Significant factors associated with incomplete Vaccination were children born at home (AOR=2.1; 95% CI: 1.32-3.36) and mothers who had two or less postnatal visits (AOR=3.4; 95% CI: 1.39-8.44). Age and number of antenatal visits of the mothers did not influence the outcome.Conclusions: Maternal related factors significantly associated with incomplete vaccination were the place of child delivery and the number of postnatal visits of mothers. The study recommends educating mothers on the importance of postnatal visits and enhancing maternal health services, especially the promotion of facility-based delivery.
