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 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. 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 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. 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. For the purpose of gaining more insight on how to develop a more effective medicine to fight the microbe in the various diseases with the first aim to targeting on knowing the amount of antibodies the body can produce to protect itself from a microbe and designing drugs that would heal one after taking a few doses. Diseases that are healed or controlled through such vaccine are chickenpox, rotavirus, measles, mumps, rubella, smallpox and yellow fever.

The other form of support vaccines is the toxic vaccine caused by bacteria that produce harmful chemicals. Illness can be caused by the toxic substance secreted by the bacteria. 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. 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. When there are sugar coating on a bacterium that ensures that bacterium antigens protect the immune system of newborn does not react to bacterium antibodies is known as polysaccharides.
