Forms of Vaccine Support Designs
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 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. 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. To learn how a microbe functions in the body a similar environment is created in the lab for learning purposes where microbes are studied. The main aim of creating microbes in a lab is to study the level at which the body is able to release antibodies to fight the different microbes and fight an illness and how to come up with relevant cure where an individual needs to take a few doses of the medicine to fight the disease of give enough assistance to the immune system to counter act against the harmful microbe. 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. Antibodies are produced after immunization to fight toxic substances and stop productions of the toxic matter. Some of the toxic and common vaccines administered in 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. 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.
