As we get older, our immune memory wanes, leaving us vulnerable to infections. Learn why this happens and what to watch for.

Just as we experience cognitive changes with age, our aging immune system becomes less efficient at recognising pathogens. This natural decline means the body is slower to respond to threats, which significantly increases the risk of serious illness. We look at the biological reality of this process and why it makes older adults more susceptible to common infections.
