[Evaluation of the Andalusia Vaccination Program in the Sierra de Cádiz Sanitary District]

Area of Science:

• Pediatrics
• Public Health
• Epidemiology

Background:

• Childhood vaccination programs are crucial for public health.
• Monitoring vaccination coverage is essential to identify gaps in immunization.
• Understanding vaccination adherence is key to preventing infectious diseases in children.

Purpose of the Study:

• To evaluate vaccination coverage in a cohort of children born in 1988 in the Sierra of Cadiz.
• To assess adherence to the recommended vaccination schedule.
• To identify common complications and contraindications for childhood vaccinations.

Main Methods:

• Retrospective analysis of vaccination records for 1319 children.
• Data collected in January 1991 for children born between January 1st and October 1st, 1988.
• Assessment of participation in the national vaccination program and completion rates for specific vaccines.

Main Results:

• 87.64% of children participated in the vaccination program.
• Initial vaccination uptake was 80.06%, decreasing over time.
• Measles/mumps/rubella vaccination coverage was 76.34%, and 2-year vaccination coverage was 66.71%.
• Approximately one-third of the child population did not complete the vaccination schedule.
• Local reactions were the most common complication, and acute infectious illness was the most frequent contraindication.

Conclusions:

• Significant dropout rates were observed throughout the vaccination calendar.
• Incomplete vaccination schedules pose a risk for this child population.
• Targeted interventions may be needed to improve vaccination completion rates in the studied region.
