🧠 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.
