Yes immune system have memory cells. they flow around the blood.
Answer is Yes. Both T-Cell and B-Cell have memory
Lymphocytes that stay in the blood after an infection is gone
Memory cells divide into plasma cells that produce the right antibody.
Memory B-cells
The idea of immunisation is that you expose the immune system to the pathogen, ennabling it to recognise the pathogen and produce mature memory Helper T cells. This means that upon its second exposure the immune system is activated faster and more efficiently, allowing the immune system to kill off the pathogen quicker. In some cases antibodies are produced that can neutralise toxins, preventing their damaging effects. If memory T cells were not produced then the immune system would have to re-learn how to fight a pathogen every time.
Memory cells
to remember the intruder for next time so your immune system can work faster.
Immunity via the production of long lived memory lymphocyte cells in the immune system.
your memory cells remember how to fight off an infection, so if you get it again then your antibodies remember how to fight it off.
As a result of memory cells, on exposure to a second infection by the pathogen the response will be quicker and stronger.
your immune system and your White blood cells produce antibodies
