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. Vaccines that happen to affect various cells or alter their functionality when the immune system is responding to microbe is termed to have negative effects thus it cannot carry its purpose effectively. 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 toxic produced by the bacteria becomes harmful to the body. Formaldehyde and sterilized water creates solution of formalin which can be used to treat inactive toxins. 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.
Polysaccharides are used to help protect immature immune systems against illness by linking toxoids and antigens to the immune system. 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.
