Types of Vaccine Support
To stop the effects or spread of a disease through a vaccine a proper vaccine has to be in place for the specific disease that should have particular characteristics relating to the relevant 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. 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.
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. Live, attenuated vaccine is a type of vaccine that is developed in the laboratory where the real microbe is weakened to a level that is not harmful to the body. 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. 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. Some example of such vaccine support diseases are smallpox vaccine, yellow fever, measles, mumps, rubella, chickenpox and rotavirus.
The other form of support vaccines is the toxic vaccine caused by bacteria that produce harmful chemicals. The bacteria toxin becomes the main cause of illness. It has been learnt from scientific findings that inactive toxins can be treated with formalin, a solution of formaldehyde and sterilized water as vaccine. When the body is vaccinated it learns how to produce antibodies to fight toxic substances. Diphtheria and tetanus are some of the common produced toxic substance by the body.
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.
