METHODS: A retrospective study involving persons who sought medical care for AEs following influenza vaccination. Data were retrieved from medical records, vaccine AE notification forms, and a computerized system for immunobiological registration. RESULTS: Sixty-six vaccinees sought medical care for AEs after immunization. The most frequent AEs were fever, headache, myalgia, and pain at the injection site. No serious AEs were reported. CONCLUSIONS: Few vaccinees spontaneously reported AEs to influenza A (H1N1) vaccine at this center.
