Relevant Population Characteristics

Age is a risk factor for influenza. Older adults are at increased risk of contracting influenza due to a natural decline in the strength of their immune system. However, people of all ages with immune deficiencies or other high-risk conditions are at increased risk for influenza. Additionally, babies between the ages of 6 months and 23 months are considered high-risk for influenza.
