All of the answers are correct. Changes in the immune system that accompany aging include T cells becoming less responsive to antigens, fewer cytotoxic T cells responding to infections, decreased numbers of T helper cells, and B cells less responsive. These changes can lead to an increased susceptibility to infections, decreased response to vaccination, and an increased risk of developing autoimmune diseases and cancer in older adults.
