|
The body’s immune system will react the same was as it did during the first exposure.

The body can only be exposed to a pathogen a second time if you do not have a vaccine.
|
|

The body will know how to fight off the pathogen quickly, because memory cells have been created after the first encounter.

Detailed explanation-1: -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-2: -The acquired immune system, with help from the innate system, makes special proteins (called antibodies) to protect your body from a specific invader. These antibodies are developed by cells called B lymphocytes after the body has been exposed to the invader. The antibodies stay in your child’s body.
Detailed explanation-3: -Q. What happens after the second time you are exposed to a pathogen? The body will not be able to fight off the pathogen quickly, because it knows how to get into the body easier. The body’s immune system will react the same was as it did during the first exposure.
Detailed explanation-4: -In a secondary response to the same antigen, memory cells are rapidly activated. This process is quicker and more effective than the primary response.
