    The immune system becomes increasingly unable to identify foreign antigens so things like autoimmune disorders are much more likely. Things like macrophages are also unable to destroy bacteria and other antigens as quickly as they used to be, and T cells which are responsible for remembering specific antigens also respond at a slower rate. Fewer white blood cells are able to respond to new antigens so the body can't defend against them efficiently as they won't necessarily remember said antigens.

    There is also the fact that the amount of antibodies produced decreases, and the antibodies find it more difficult to attach to the antigen
