Defence against Disease and the Immune System In this essay I have distinguished clearly between active/ passive‚ natural/artificial immunity and described some methods of vaccine production. I have critically compared the effectiveness of the smallpox vaccination programme with programmes aimed at control of measles‚ polio‚ influenza‚ malaria and cholera. Introduction (Immune System‚ 2012) “The immune system is made up of a network of cells‚ tissues‚ and organs that work together

Although people say that animal testing does not give results‚ vaccines such as the vaccine for hepatitis B and Polio have successfully been created and have worked in decreasing the amount of cases. As well as the testing is most efficient way of finding a cure quickly‚ scientists can develop all sorts of cures not only to humans

English Independent Studies Assignment 4 I believe that state mandated administration of childhood vaccinations is justified for the following reasons; First and foremost‚ mandating vaccinations in children provides the opportunity to eliminate certain illnesses. Second‚ mandating vaccinations lowers the risk in the illness spreading and multiplying. And third‚ vaccinations could be used to collect money which could then be used for things like research towards developing new‚ more effective

happens‚ the bacteria or virus attack the body’s cells and begin to multiply. When this happens‚ it is known as an infection which in turn make people ill. Our body uses its immune system to fight of the infection that has began spreading in the body. Vaccines are used to help our immune system develop an immunity by imitating the infection. This means that there is a small amount of the bacteria or virus introduced to the body but it does not make the person ill. This causes the immune system to create

Another complaint from those who oppose government required vaccinations is the belief that vaccines are more dangerous than the diseases/side effects they prevent‚ and that vaccinations are ineffective. The American Academy of Pediatrics‚ as well as other organizations claim that immunizations can cause “seizures‚ progressive encephalopathy‚ and death” (“Should” 7). Skeptics believe that these rare side effects are worth risking communal‚ and individual health. They want to put themselves and

vaccinations. Vaccines are normally given to healthy individuals for the prevention of diseases. Vaccines work by using a human host to provide a stimulus to the immune system. Immunization is used for viral and bacterial diseases. Rappuolli reports and predicts‚ "Vaccines will not only be used to prevent infections‚ but also to cure chronic infectious diseases‚ tumors‚ diseases and allergies." (1999) Even though there are risks involved with being vaccinated‚ there is no doubt that vaccines have been

Despite overwhelming evidence supporting the safety and benefits of vaccines‚ fear of vaccinations has proven resistant to information leading to a rise in refusals among parents in developed countries (Dipietro). In modern society with the rapid pace of vaccine development along with new technology‚ the history and importance of vaccines seem forgotten‚ leading people to underestimate the severity of infectious diseases. “Those who do not remember the past are condemned to repeat it‚” George Santayana

Is the MMR vaccine safe? About Vaccines Vaccines work by stimulating our immune system to produce antibodies without actually infecting us with the disease. Antibodies are substances produced by the body to fight disease. Vaccines generate the immune system to produce its own antibodies against disease‚ as though the body has been infected with it. This is called "active immunity". If the vaccinated person then comes into contact with the disease itself‚ their immune system will recognise it

case of the disease in which the virus remains in the person for the remainder of their life (Vaccines). The hepatitis b vaccine can be considered the first cancer preventing vaccine as it prevents hepatitis b‚ which is the leading cause of liver disease. This vaccination is very safe as the strain of hepatitis b in the vaccine is a synthetic version of the disease‚ therefore‚ it is impossible for the vaccine to cause hepatitis

Judgment is commonly referred as an evaluation or an opinion. The word is often seen with a negative connotation of criticism. Yet‚ as much of a negative connotation as it withholds it is an action used to give one’s opinion about something. As our time period changes and the norms and standards change so does our judgment and views of the world. Thus‚ leading to the judgment of significant events that allow for the development of knowledge. This allows for the questioning of certain areas of knowledge
