When our body encounters a pathogen for the first time, the immune response is generally low but on exposure to the same pathogen again, the immune response by the body is much more compared to the first exposure. Why is it so?

  • 0

The body remembers the pathogen from the first attack and creates special memory cells. When the same germ attacks again, the immune system responds quickly and strongly, protecting the body more effectively.

    1. When our body first encounters a pathogen, it learns to fight it by creating memory cells. These cells “remember” the invader. If the same pathogen enters the body again, the immune system quickly recognizes and attacks it more strongly and efficiently. This faster and stronger immune response helps the body recover quickly and even prevent illness, showing the power of acquired immunity.
