Immunological memory

Definition

Immunological memory is the capability of the immune system to quickly and efficiently recognize antigens that the body has previously encountered, allowing for a faster and more effective response upon subsequent exposures. This feature underlies the principle behind vaccinations and provides long-lasting protection against diseases.
