The Different Types of Vaccines
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 Good vaccines should not affect the way other cells behave but rather only fight the relevant microbes that cause an illness. 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. For a support vaccine to be termed as suitable it should poses some level of compatibility with other medications that can be related to similar ailments and also at what part of the world is the medicine recommended for use are some of the issues that should be factored in when designing good vaccine support medication.
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. 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. 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. A number of examples diseases are yellow fever, smallpox, 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. Formalin can be used to treat inactive toxin which is a solution of formaldehyde and sterilized water. 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. Diphtheria and tetanus are some of the common produced toxic substance by the body.
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.
