    GlossaryMemory B Cell

    remember pathogens for faster future immune responses

    A Memory B Cell, also known as a Memory B Lymphocyte, is a type of white blood cell that plays a crucial role in the immune system. After an initial infection or vaccination, these cells "remember" the specific pathogens they encountered, allowing the body to mount a faster and more effective response if the same pathogen invades again in the future. This immunological memory is essential for long-term immunity and is a key principle behind how vaccines work.
