Abstract

Objectives: To determine the rate and associated factors of full and on schedule immunization with 8 types of vaccine on under 1 year-old children at Phan Thiet city, Binh Thuan province in 2020. Methods: A cross-sectional study. Information on vaccination status was collected from immunization report from 370 children aged 9-21 months. A total of 370 mothers/caretakers over 18 years old were interviewed from December 31, 2020. Results: 78.11% of children were fully immunized and 1.98% were immunized on schedule. Some association factors with full immunization of children under 1 year were place of residence in rural compared to urban areas (PR: 1.23, 95% CI: 1.11; 1.36, p<0.001), presence of vaccination document (PR = 4.81, 95% IC: 1.36; 17.06, p<0.001), the mother knew the schedule and place of immunization (PR 2.38, 95% IC: 1.07; 5.32, p<0.001), sick children delays and delayed well children immuzination were statistically significantly associated with the full immunization (PR=0.84, 95% IC: 0.72; 0.98, p=0.01 and PR 0.85, 95% IC: 0.77; 0.95, p<0.001), negative attitude of the mothers such as no beliefs in immunization (PR 0.83, 95% IC: 0.7; 0.98, p=0.01) or misconceptions on immunization (PR 0.76, 95% IC: 0.60; 0.97, p<0.001), shortage of vaccines supplies (PR = 0.81, 95% IC: 0.67; 0.97, p=0.01), the lack of time (PR 0.77, 95% CI: 0.63; 0.95, p<0.001) and mother’s education level. The full of vaccination coverage were 1.27 (PR = 1.27, 95% CI: 1.05;1.54, p=0.04) and 1.23 (PR = 1.23, 95% CI: 1.01; 1.50, p=0.01) or (PR = 1.23, 95% CI: 1.01, 1.49; p=0.01) times higher in children of mothers with primary and secondary or higher high school ducation respectively than children of mothers with no education. Conclusion: Full immunization coverage in this study was lower than the national target. Improving maternal education is important for increasing vaccination coverage. On the other hand, it’s necessary to communicate knowlegde about expanded programme of immunization with 8 types vaccines for mother/carertakes have children under 12 months. Besides, aregular supply of vaccines will reduce the missed opportunities, thus maintaining high vaccination coverage in children.
