TeleWatch is an automated telephone/Internet-based system that collects medical product adverse event reports in real-time through an algorithm driven by the patient. 1341 patients, who received yellow fever vaccine and were recruited through 15 travel clinics, contacted the system within 48 h of vaccination and 765 (57%) made follow-up contacts. Participation rates were higher among females and persons older than 60 years of age. TeleWatch can be expanded for use in large campaigns involving influenza or other vaccines.
