Aging and multiple morbidities increase the risk for severe outcomes from influenza. 90% of hospitalisations relating to pneumonia and influenza occur in those aged 65 and older, even though they only comprise 15% of the population. As people age, so the impact of influenza changes from primarily respiratory to cardio-respiratory outcomes. A long lament has been that influenza vaccine is least effective for those who need it most. Several approaches have sought to improve vaccine effectiveness but few have been formally studied through prospective randomized-controlled trials. The presentation will largely focus on clinical outcomes from the randomized controlled trials for vaccines licensed for healthy elderly. This will specifically relate to primary endpoints of protocol-defined influenza in healthy people, and all-cause hospitalisation among frail elderly living in long-term care settings. Related post-hoc analyses from the long-term care studies will also discuss relative duration of benefits to respiratory and non-respiratory outcomes and the presumed mechanism for these, and herd immunity.
