The purpose of this persuasive essay is to take a position on the topic; Compulsory immunisation for all Australian children and the issues linked to compulsory immunisation. Firstly the persuasive essay will define and immunity; following this relevant diseases to immunisation will be discussed. Finally the essay will explore the major arguments associated with compulsory immunisation for children.

The immunisation is the process of protection against harmful diseases. Immunisation is a method of disease prevention to reduce the likely hood of developing a disease. Immunisation is a process of receiving a vaccination through an injection. (Australian Government, 2009) Then the body produces an immune response as if their body was being attacked by a disease, however without suffering symptoms. In future the immune system will respond fast enough to prevent the disease from developing.

There are different types of vaccines for different diseases. As every disease has its own characteristics therefore for every disease you need a different vaccine. The national immunisation program schedule informs all on when immunisation is needed. Different vaccines are to be taken at different times. In some circumstances immunisation is only needed if the person is to travel to a different country. (Australian Government, May, 2009)

There are many minor side affects associated with immunisation however they only last a short amount of time and all recover without any problems. The common side effects following immunisation include redness, soreness, swelling at the site of the injection, mild fever and being grizzly or unsettled. Serious reaction to immunisation is very rare, allergic reactions to part of a vaccine maybe life threatening. Not everyone in the community can be immunised. If someone has a severe allergic reaction to a component in the vaccine they can not be immunised. A person with an immune system which is suppressed can normally not be immunised also with the vaccine containing modified ‘live’ viruses.

Immune Function
Immunity is an ability to be immune, immunity involves two aspects specificity and memory. Specificity is the ability to recognize and respond to a particular foreign cell. Memory refers to the fact of a second exposure of the same organism producing a larger and more rapid response. Immune response involves lymphocytes and phagocytes and includes both humoral and cell-medicated mechanisms. Phagocytes are involved in removing debris ad flight infections, phagocytes are attracted to the site of infection engulfing harmful bacteria and damaged cells. The lymphocytes are responsible for the production of antibodies and are produced in the bone marrow. There are two main groups of lymphocytes; T cells and B cells they work together to provide the body’s specific immune response (Spencely, et al. 2004).

The process of the immune response works in different stages. The first stage in the immune response is the inflammatory response. The inflammatory response increases the blood flow to the effected area; causing redness. The inflammatory response then increases permeability of blood cells, and the movement of leucocytes out of blood vessels into damaged tissues. The inflammatory response allows antibodies and complement to find the site of infection quickly.

The next stage in the immune response is the histamines. Histamines are a naturally occurring substance in the body. The function of the histamines is to dilate the blood vessels to manage internal environment. An excessive production of histamines is triggered by contact with certain allergens resulting in over-dilation and inflammation of tissues.

The next stage in the immune response is the white blood cells. The white blood cells are slightly larger than the red blood cells, though white blood cells are not as common. There are different types of white blood cells; Phagocytes and lymphocytes. As...
