|
|
The primary immune response is much faster
|
|
|
The numbers of antibodies produced in the primary response is greater
|
|
|
In the secondary response the antigen is disabled in a shorter amount of time
|
|
|
There is no difference between the two immune responses
|
Detailed explanation-1: -The main difference between primary and secondary immune response is that primary immune response occurs in response to the primary contact with the antigen whereas secondary immune response occurs in response to the second and subsequent exposure to the same antigen.
Detailed explanation-2: -The primary immune response occurs after the first exposure to an antigen. A primary immune response results in the generation of memory immune cells. A secondary immune response occurs as a result of a second exposure to an antigen.
Detailed explanation-3: -Primary immune response takes a longer time to establish immunity. Secondary immune response takes a shorter time to establish immunity. Generally, low amounts of antibodies are produced during the primary immune response. Generally, high amounts of antibodies are produced during the secondary immune response.
Detailed explanation-4: -32.2. In contrast, the secondary immune response to an antigen previously encountered by an individual (e.g., after vaccination or infection) is mediated by memory T cells and is significantly stronger and faster than a primary response.
Detailed explanation-5: -How is the secondary response different from the primary response in terms of antibody concentration in the blood? The secondary response is slower, but produces more antibodies than the primary response.
