As we age, our immune system naturally becomes less effective at fighting off infections, making adults over 65 particularly vulnerable to influenza and its complications. The annual flu vaccine is specifically formulated to protect against the strains of influenza virus that are expected to circulate during the upcoming flu season.
For older adults, flu isn't just an inconvenience – it can lead to serious complications including pneumonia, bronchitis, and worsening of existing health conditions like diabetes, heart disease, or lung conditions. Hospitalization rates for flu-related complications are significantly higher in the over-65 age group, making vaccination a crucial preventive measure.
