immune memory
Pathogen recognition persistence
Immune memory is the body's ability to recognize and respond more rapidly to pathogens it has encountered before.
After an initial infection or vaccination, specialized cells retain information about the invader, enabling a faster, stronger defense upon re-exposure.
This is why you typically don't get chickenpox twice, and why booster shots work: The vaccine builds immune memory against the virus.
