In this essay I will explain the processes of immunity, immunisation and the resulted antibody formation due to natural and artificial exposure to antigens.
Immunity is the body's ability to resist a particular infection or toxin by the action of specific antibodies or sensitized white blood cells. Immunization is the process that makes one immune to infection, typically by inoculation/vaccination.
The body's first line of defence to prevent pathogens and harmful microorganisms from entering and causing disease and infection, is the skin, chemicals in tears and sweat and stomach acid. Pathogens sometimes overcome these first line defences and their responses, what happens next?
The body's immune system is the next specific response to pathogens being detected in the body. The response includes B and T Lymphocytes ...

(Delves, 2015)
With the ability to learn, adapt and remember, acquired immunity develops a memory for antigens entering the body, making them able to learn the best way to attack each antigen and develop new memory. Its development takes time after the initial exposure, but post exposure, the antigen is remembered and responses are adequate enough too rapidly dead with the antigen. Lymphocytes (T and B cells) mentioned previously are responsible for the process of acquired immunity, and begins with the response of the antigen allowing antibodies to be produced by B cells, initiating the acquired immune response. There are other components present in this process such as "Dendritic cells", which break down the antigen so T cells can recognize them more effectively. Also Cytokines which are messengers of the immune system are released when an antigen is
