1. A cohort of Elderly Health Centres was examined to determine whether influenza vaccination decreased hospitalisation and mortality.
2. In the influenza season, influenza vaccination reduced all-cause mortality by half and cardiorespiratory hospitalisation by a quarter. The extent to which influenza vaccination protects older people from serious morbidity and mortality needs to be confirmed in appropriately designed studies, so that scarce health care resources can be used effectively.
