People 65 years and older are at higher risk of developing serious flu complications compared with young, healthy adults. This increased risk is due in part to changes in immune defenses with increasing age. While flu seasons vary in severity, during most seasons, people 65 years and older bear the greatest burden of severe flu disease. In recent years, for example, it’s estimated that between 70 percent and 85 percent of seasonal flu-related deaths have occurred in people 65 years and older, and between 50 percent and 70 percent of seasonal flu-related hospitalizations have occurred among people in this age group.
