🧠 Memory Effect
  • After surviving the infection, the immune system remains vigilant.
  • Memory cells, called memory cells, develop during the immune reaction:
    • Memory T-cells and memory B-cells persist for years or decades.
    • When encountering the same pathogen again, these cells recognize the antigen quickly and can initiate a much faster and more effective defense.
  • Process Time on First Contact Time on Second Contact
    Activation slow very fast
    Antibody production after several days often within hours
  • This memory effect is the basis for vaccinations, which train the immune system without causing a real infection.
