Assessment on immunization status of infants in selected barangay in Tuguegarao City:

AbstractAim: This study examined the relationship between mothers’ perceptions of local infant immunization interventions and the actual immunization status of their infants in three barangays of Tuguegarao City, and used the findings to propose enhancement strategies for local intervention planning.Methodology: A descriptive-correlational design was employed. Using Cochran’s formula and stratified sampling, 175mothers (aged 20–35) of infants aged 0–12 months completed a structured questionnaire assessing sociodemographic characteristics, perceived effectiveness of five intervention domains (educational promotion; telephone calls/reminders; mass media; identification of target children; evaluation of immunization status), and infants’ vaccine uptake. Reliability testing (Cronbach’s α = 0.74), descriptive statistics, and Pearson correlation (α = 0.05) were used for analysis.Results: Coverage was high for early doses (BCG and Hepatitis B birth dose = 100%), moderate for several vaccines (pentavalent 90.3%; OPV 90.9%; PCV 91.4%; IPV 90.9%), and low for MMR (fully immunized = 15.4%). Correlation analyses showed no statistically significant relationship between mothers’ assessments of intervention programs and infants’ immunization status (all p > 0.05), indicating that perceived program effectiveness alone did not predict complete vaccination. Contextual factors such as service availability, follow-up systems, and access barriers likely contributed to incomplete coverage.Conclusion: Strengthening community outreach, improving access (including mobile clinics and tracking systems), and providing ongoing competency-based training for Barangay Health Workers (BHWs) are recommended to improve full immunization coverage in the targeted barangays.
