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. Moreover, vaccines should be designed in such a manner that they are against illness microbe only without affecting the body cells. 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. 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. This is done for the purpose of studying how the real microbe behaves in the natural infection. 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. The toxic produced by the bacteria becomes harmful to the body. Formalin can be used to treat inactive toxin which is a solution of formaldehyde and sterilized water. Antibodies are produced after immunization to fight toxic substances and stop productions of the toxic matter. Diphtheria and tetanus are some of the common produced toxic substance by the body.
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. A polysaccharide is a bacterium possessing an outer coating of sugar molecules which disguise a bacterium antigens so that the immature immune system of a kid can’t recognize or respond to them.
