GCSE Combined Science · key term
A long-lived lymphocyte formed during an immune response that enables a faster response if the same antigen is encountered again.

Specification 4.3.3.5 · Paper 1, Paper 2
A white blood cell that remains after an initial immune response and enables a rapid response when the same pathogen enters again.
Revise: VaccinationSome white blood cells remain as memory cells, allowing the immune system to recognise the same pathogen later.
Specification B6.3i, B6.3j · Biology Paper 2
The body produces the antibodies; the vaccine does not supply them. Memory cells explain the faster response.
Explain a faster response to reinfection using memory cells and rapid antibody production, not by saying that the body ‘remembers’ without explaining how.
A vaccine supplies antigens, not ready-made antibodies. Explain that the person's lymphocytes produce antibodies and memory cells.

A long-lasting lymphocyte that enables a faster specific immune response when the same antigen is encountered again.
After an infection, some lymphocytes remain as memory cells. These provide lasting recognition of the particular antigen.
Biology, Combined Science
A long-lived lymphocyte that enables a faster, larger antibody response when the same antigen is encountered again.
Revise: Human Immune SystemAfter the infection, some lymphocytes remain as memory cells. If the same antigen is encountered again, these cells enable the correct antibodies to be produced much faster and in larger quantities. The pathogen may be destroyed before symptoms develop.
A long-lived immune cell formed after exposure to an antigen that enables a faster response if the same antigen is encountered again.
