Smart Ideas: Vaccines Revisited

The Different Types of Vaccines

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. 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. 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. Some example of such vaccine support diseases are smallpox vaccine, yellow fever, measles, mumps, rubella, chickenpox and rotavirus.

The second form of support vaccine is the toxic vaccine that emanates from harmful chemicals from bacteria those secret toxins. 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 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.
