This 2 arm study will evaluate the efficacy and safety of Tamiflu in the seasonal prophylaxis of influenza in immunocompromised patients (as represented by transplant recipients). Transplant recipients enrolled when influenza is circulating in the community will be randomized to receive Tamiflu syrup or capsules 30mg-75mg daily (depending on body weight) or placebo for 12 weeks. Influenza symptoms and safety data will be recorded throughout the study. The anticipated time on study treatment is <3 months, and the target sample size is 100-500 individuals.
