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. 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. Additionally there are some factors that should be considered when coming up with an effective vaccine which should be how friendly the medicine is with other forms of treatment and the region the patients are in the world just to mention a few of the considerations.
There are five main categories of vaccines which are: attenuated vaccine, toxic vaccine, conjugate vaccine, inactive vaccine and subunit vaccine which are discussed broadly below. 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. 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 second form of support vaccine is the toxic vaccine that emanates from harmful chemicals from bacteria those secret toxins. 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. When the body is vaccinated it learns how to produce antibodies to fight toxic substances. The common toxics produced by the body are tetanus and diphtheria.
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.Source: click for more info
