The prevalence and types of childhood vaccination administration errors
Abdullah Al Saleh
Background: Vaccination administration errors are preventable events that can affect patients via inadequate immunological protection, injury, increased costs, inconvenience, and reduced confidence in the healthcare delivery system. Objective: To calculate the prevalence of vaccination errors, determine which types of errors are most common, and identify opportunities for prevention. Methods: A cross-sectional study was conducted at the National Guard Comprehensive Specialized Clinic in Riyadh, Saudi Arabia. The study population consisted of 2580 children who received routine vaccinations at the Well Baby Clinic. A checklist was used to collect data regarding vaccination administration errors. Results: The prevalence of vaccination administration errors was 0.57%. The most common vaccination errors were vaccine dosing errors, administration of the wrong vaccine, and incorrect vaccination intervals. Conclusions: Vaccine administration errors are uncommon; however, the impact of vaccination errors on the health of individuals and the population can be severe. Prevention strategies to avoid these errors should be considered.
