More time has gone by
|
|
Memory cells are present
|
|
Antibodies already exist for the antigen
|
|
Less strength is required
|
Detailed explanation-1: -Because of the generation of memory cells, the secondary immune response is faster and stronger, leading to more effective pathogen elimination in comparison to the primary immune response.
Detailed explanation-2: -Secondary immune response is quicker and stronger than the primary one.
Detailed explanation-3: -In the primary response to infection, antibodies are secreted first from plasma cells. Upon re-exposure to the same pathogen, memory cells differentiate into antibody-secreting plasma cells that output a greater amount of antibody for a longer period of time.
Detailed explanation-4: -If we are ever reinfected with that same type of pathogen, our body will respond with a secondary immune response. This is a much quicker and more efficient response because our body now contains the memory cells with the antibodies that are specific to that reinvading antigen.
