New influenza vaccines for older people may provide improved protection against influenza-related disease

Influenza is the leading vaccine-preventable cause of morbidity and mortality each year in Australia.1 Older people are particularly at risk of severe outcomes from influenza, including hospitalisation, pneumonia, acute myocardial infarction and death.1-3 In 2017, the largest influenza season since the 2009 pandemic, 53 983 (22%) of all 249 932 notified influenza cases were in people aged ≥ 65 years (Box 1), and more than 90% of the 1100 influenza-related deaths reported occurred in older adults.4-6 Furthermore, these numbers are widely recognised as an underestimation of the true burden of disease.
