Immune Response

The immune system—the complex combination of organs, cells and chemicals that the body uses to defend itself against invasion by bacteria, viruses, and other foreign bodies—is critical to maintaining our health, particularly as we age. Unfortunately, older adults are disproportionally vulnerable to infections, suffering high rates of debilitating illness and death despite the use of antibiotics, vaccines, and other modern medical treatments and therapies.

Researchers continue to explore the immune response and how it may be manipulated to boost our ability to fight a wide range of age-related diseases and conditions.
