Vaccine support is a very fragile unit in medication as it involves the study of illness characteristics and how to come up with a cure of the disease. For a vaccine to meet its purpose in the right manner of functionality it should working such a manner that it fights the microbes that cause the disease without affecting or altering other elements of the body functionality. For a vaccine to be effective it must have so crucial characteristics such as the ability to fight the harmful elements in the body cells and not harm other cells that are not affected by the virus or bacterium without altering their functionality. Also when designing a vaccine varying considerations should be taken such as how compatible the vaccine is with other related ailments and the region in the world it will be used.
The main type of support vaccines are five and will be discussed in the article and they are: toxic vaccine, inactive vaccine, attenuate vaccine, subunit vaccine and conjugate vaccine. The first type of vaccine is the attentive or live vaccine that is made in the lab for the purpose of learning by creating a weakened and is harmless to the body as it cannot cause illness but its present in the bodies system. To learn how a microbe functions in the body a similar environment is created in the lab for learning purposes where microbes are studied. The long run aim is to rate the amount of antibodies that the body can possibly release to fight the microbe and how to design a drug that can fight the disease with a few doses. Diseases that are healed or controlled through such vaccine are chickenpox, rotavirus, measles, mumps, rubella, smallpox and yellow fever.
The other form of support vaccines is the toxic vaccine caused by bacteria that produce harmful chemicals. The toxic produced by the bacteria becomes harmful to the body. It has been learnt from scientific findings that inactive toxins can be treated with formalin, a solution of formaldehyde and sterilized water as vaccine. After the body is immunized it learns how to fight the natural toxic substance by releasing antibodies that fight the toxic substance and finally stop its production. The common toxics produced by the body are tetanus and diphtheria.
Thirdly, when designing a conjugate vaccine the scientists link toxoids or antigens from a microbe to the immune system to recognize it to the polysaccharides where this linkage helps immature immune system like that of an infant to react to polysaccharide coating and defend that body against diseases caused by bacterium. When there are sugar coating on a bacterium that ensures that bacterium antigens protect the immune system of newborn does not react to bacterium antibodies is known as polysaccharides.
