“Any older adult can tell you that your body changes as it ages. Muscles weaken, metabolism slows, and hair follicles turn gray. Our immune system also changes with age. The older we get, the more our immune system slows, increasing our risk for certain diseases. Fortunately, vaccines were created to boost the body's immune system.”
