Immunologic memory; the ability of the immune system to "remember" a foreign substance to which it has been exposed, and to produce an even more effective response to it upon subsequent reexposure.
The heightened immunologic reaction elicited by a second or subsequent exposure to a particular antigen such as a pathogenic microorganism (e.g., bacterium, fungus).
renewed rapid production of an antibody on the second (or subsequent) encounter with the same antigen
The faster and greater immune response produced by an animal who has previously encountered that specific antigen. Memory cells are responsible for this more efficient response. Also called 'secondary response.'
a heightened immunologic response stimulated by a second or subsequent exposure to a specific antigen.
the heightened immunologic reaction elicited by a second or subsequent exposure to a particular pathogenic microorganism (e.g., bacterium, fungus, virus), toxin, or antigen. (See also memory cells.)
An immune response to an antigen or pathogen to which the individual was previously exposed. This immune response occurs more quickly and is often stronger than the response induced by the first injection or vaccination, also called the secondary response.
The sudden and exaggerated production of antibodies after a second exposure to a specific antigen; due to the activation of memory B cells.
