The Different Types of Vaccines

Coming up with a vaccine is very sensitive since it requires a lot of keen design formula that that should have elements to fight a disease Good vaccines should not affect the way other cells behave but rather only fight the relevant microbes that cause an illness. A good vaccine is one that is used in the right manner by the immune system body cells without affecting the infected cells in the body or altering their functionality. Additionally there are some factors that should be considered when coming up with an effective vaccine which should be how friendly the medicine is with other forms of treatment and the region the patients are in the world just to mention a few of the considerations.

There are a number of main forms of support vaccine medications that are: attenuated vaccine, conjugate vaccine, toxic vaccine, subunit vaccine and inactive vaccine just to mention a few that will be discussed below. 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. By developing a microbe in the lab it is to create a similar environment of that which the virus or bacteria thrives on so as to learn how it actually behaves in the body. 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.

Harmful chemicals are produced by bacteria that is toxic to the body cells. Illness can be caused by the toxic substance secreted by the bacteria. Formalin can be used to treat inactive toxin which is a solution of formaldehyde and sterilized water. 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.
