The Different Types of Vaccines
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. Good vaccines should not affect the way other cells behave but rather only fight the relevant microbes that cause an illness. 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. These type of vaccine is developed in the vaccine where the real microbe in weakened in the lab to such a point that it cannot harm the body cells causing illness where the real behavior of the microbe is studied so as to find a suitable vaccine. To learn how a microbe functions in the body a similar environment is created in the lab for learning purposes where microbes are studied. For the purpose of gaining more insight on how to develop a more effective medicine to fight the microbe in the various diseases with the first aim to targeting on knowing the amount of antibodies the body can produce to protect itself from a microbe and designing drugs that would heal one after taking a few doses. Diseases that are healed or controlled through such vaccine are chickenpox, rotavirus, measles, mumps, rubella, smallpox and yellow fever.
Harmful chemicals are produced by bacteria that is toxic to the body cells. The toxic produced by the bacteria becomes harmful to the body. Formaldehyde and sterilized water creates solution of formalin which can be used to treat inactive toxins. 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. Some of the toxic and common vaccines administered in the body are tetanus and diphtheria.
During the development of conjugate vaccine the scientists link the antigens or toxoids to a microbe and the immune system to distinguish the polysaccharides to the immature immune system such as of young ones to react to polysaccharide coating and protect the cells against bacterium’s. A sugar molecules coat a bacterium that disguises the bacterium antigens for the immune system of an infant not to react to them is referred to as polysaccharides.
