Question

What does the term ' memory' of the immune system mean?

Answer 1

Immunological memory is the ability of the immune system to quickly and specifically recognize an antigen that the body has previously encountered and initiate a corresponding immune response. ... Immunological memory is the basis of vaccination.

Answer 2

During an immune response, B and T cells create memory cells. These are clones of the specific B and T cells that remain in the body, holding information about each threat the body has been exposed to! This gives our immune system memory.
