As the global population ages, age-related diseases are placing an ever-increasing burden on Western societies—economically, socially, and personally. A central factor in these conditions is a progressively dysfunctional immune system, which becomes less effective at fighting infections, responding to vaccinations, and regulating inflammation as we age.
The decline in immune function, known as immunosenescence, leads to a higher susceptibility to infections, chronic diseases, and cancer. Moreover, it contributes to the development of autoimmune disorders, where the immune system mistakenly attacks the body’s own tissues. This immune deterioration significantly impacts the quality of life and increases healthcare costs.
