The immune system protects the body against illness and infection caused by bacteria, viruses, fungi or parasites. It is really a collection of reactions and responses that the body makes to damaged cells or infection.ancer can weaken the immune system by spreading into the bone marrow. The bone marrow makes blood cells that help to fight infection. Weakening of the immune system happens most often in leukaemia or lymphoma.
If you have HIV and do not take HIV medicines, eventually - typically, over a number of years - your viral load increases and the number of CD4 T cells decreases significantly. Your immune system becomes very weak. This means that you are open to getting infections and your body is unable to fight the infection.
