Several studies in adult medicine demonstrated that mailed reminders improve the rate of immunization against influenza.3-5 Mailed reminders have also been effective in improving compliance with immunizations in pediatric clinics.6 We were unable to find any studies addressing the effectiveness of mailed reminders in improving the rate of influenza immunization in pediatric clinics. Accordingly, we performed a controlled clinical trial to answer the following question: do computer-generated reminder letters improve the rate of influenza immunization in children
