EPH97 Routine vaccination coverage in El Carmen de Bolivar, Colombia: a survey of children under 6 years of age, 2021

Objective: We evaluated the coverages of the expanded program of immunization in children under 6 years old for 2021. Methods: We conducted a cross-sectional survey from October to November of 2021, in poor municipality of Colombia (73,653 inhabitants, 5,796 ,6 year) mainly affected by the armed conflict. A twostage cluster sampling with a precision of 5.5% and a design effect of 2 was performed. We considered a non-response rate of 20%. In each household, we determined age-appropriate routine antigen coverage for children ,6 year of age based on vaccination card. Basic sociodemographic data from household surveys of caregivers of the children were gathered. Multivariate regression analysis was conducted to show timely-vaccine coverages key drivers. Results: Overall coverage of most biologics at 18 months of age was .94%, based on vaccination cards of 175 children ,6 years old (86.2% of all surveyed). Vaccination absolute coverages for yellow fever and second doses of influenza, routine antigen boosters (first of MMR [measles, mumps, rubella] and second boosters of polio and DPT) ranges between 80-84%. Three biologics (BCG, hepatitis B, rotavirus) had age-appropriate timely vaccination coverages between 90-94%. Most vaccine timely coverage were between 74.1-89.7% (pneumococcal [first and third doses]; pentavalent, polio, and MMR [first and second doses]; DPT and polio boosters). The second dose of pneumococcal vaccine and the third of polio and pentavalent showed coverages from 62.7-64.8%. Lowest timely vaccination coverages were yellow fever (3.4%) and influenza (46.8% for first and 26.8% for second dosage). Mother’s education and birth order were significantly associated with higher timely immunization odds. Conclusion: Our findings highlight the need for concerted efforts to improve timely routine immunization coverage in a postconflict and pandemic scenario, especially for yellow fever and influenza vaccines. Low coverages for several vaccines were potentially explained for vaccine shortages.
