Write a short note on immunization
Answers
Immunisation: Immunisation is the phenomenon used for the working of the increasing effect of a specific antibody which are continuously produced and developed accordingly by memory B- cells and T- Cells against the potential attack of a pathogen which has caused a similar invading and attack on the body's tissue and systems before. It is carried out by or through the vaccination and injection of an antiserum which provide the first line of previously attacking pathogen and protect the immune system including activating all other Defence components inside the body. When an immunized person is by chance, attacked by that same particular or new pathogen against that antiserum and vaccine provided, the existing antibodies are going to perform an immediate attack to the antigen itself. By then memory T- cells and B- cells give rise to a massive crop of lymphocytes and antibodies to ultimately eliminate all the potential remains pathogens left in the body.
Hope it helps you my dear friend..
Immunization, or immunisation, is the process by which an individual's immune system becomes fortified against an agent (known as the immunogen).
When this system is exposed to molecules that are foreign to the body, called non-self, it will orchestrate an immune response, and it will also develop the ability to quickly respond to a subsequent encounter because of immunological memory. This is a function of the adaptive immune system. Therefore, by exposing an animal to an immunogen in a controlled way, its body can learn to protect itself: this is called active immunization.
The most important elements of the immune system that are improved by immunization are the T cells, B cells, and the antibodies B cells produce. Memory B cells and memory T cells are responsible for a swift response to a second encounter with a foreign molecule
