A strong immune system is essential for protecting older adults from infections, seasonal illnesses, and chronic disease complications. As people age, immunity naturally weakens, making seniors more vulnerable to flu, pneumonia, and other infections. In a large city like Chicago, where seasonal weather changes and urban living increase exposure to viruses, maintaining strong immunity becomes even more important.
