Vaccinating Against Disease

Through the understanding of infectious diseases, researchers have been able to create several types of vaccines to help prevent a variety of life-threatening illnesses. Scientists develop immunizations using different techniques to treat diseases. These types include: live, killed, toxoids, subunit, and conjugate vaccines. Vaccinations that are the live type use a specific process which when administered will expose the patient to the actual disease, but in a much

Vaccines are designed to put foreign antigens into the body so the body will produce antibodies to fight it off. When an antigen is

Varicella or other known as the chickenpox vaccination. The chickenpox vaccine is a shot that can protect nearly everyone who gets it from catching chickenpox. It 's also called the varicella vaccine because chickenpox is caused by the varicella-zoster virus. The vaccine is made from a live but weakened, or attenuated, virus (Children 's Vaccines Health Center). This vaccine is mainly for children and adults who have not had chickenpox before. There’s no need for the vaccine if you have already had them.

A clear definition of a vaccination is, "the generic term for immunization procedures. Immunization is a procedure whereby living or nonliving materials are introduced into the body…:" (Nosal, 1999) The concept that people who survive an infectious disease do not get the same disease again is the basis for the administering of 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

Many people may wonder “How do vaccines work?” well according to the article, they work by “introducing diluted viruses or bacteria into a person’s body via injection”. (“Issues & Controversies”) When you are given a vaccine, your body thinks the small amount of the virus is the actual disease itself. Therefore the body’s immune system creates antibodies that help fight off the disease in which that was injected into the body. when this happens the human body is teaching the

A vaccine is the injection of a dead disease causing microorganism into the body. After injection, the immune system will attack the infection and build up an immunity against it. In the future the chance of infection is much lower since the body has already built up immunity.

Vaccines are made from microorganisms and they are given to a person to produce reduced sensitivity or increased immunity to an infectious disease. can be protected or made susceptible to a disease. Vaccines contain organisms that have been killed or weakened. They prepare the body to fight disease without exposing it to disease symptoms.

The definition of a vaccine is that antigens prepared in such a way that they can promote active immunity without causing a disease. The way they promote active immunity without causing a disease means that you can get the shot without worrying about getting any kind of disease. There have been quite a few types of research on various kinds of vaccines and how they have been changed before anyone getting the

This source informs mainly about the immune system on it functions and how it's seemed to be benefited by vaccines. Infections can occur in the body system and if it’s not treated then it could become a disease. However, vaccinations can lower the risk of getting a disease by preventing it. As a matter of fact, vaccination works to stimulate a specific immune response that will create B and T cell responses specific to a certain pathogen.This source is biased because it states how vaccines help to prevent any infection to get in the immune system.

Vaccines prepare the body to fight diseases without giving the recipient the disease symptoms. The vaccine is made up of “foreign invaders” called antigens. The

Vaccination is the usage of prepared serum called vaccine to prevent particular diseases. Vaccines are drugs that comprise of weakened or dead bacteria or viruses. Individual immune system reacts by manufacturing antibodies when one takes any of the vaccine. Antibodies are the elements that weaken or terminate organisms that are causing disease. As soon as the individual is exposed to live bacteria or viruses of the similar kind that existed in the vaccine in future, the antibodies prevent individuals from becoming sick. Through the vaccine usage many sicknesses that formerly caused widespread illness, disability, and death can now be prevented.

Immunizations are very important in order to prevent the spread of certain communicable diseases. A vaccine is a “suspension of infectious agents, components of the agents or genetically engineered antigens” (Tamparo & Lewis, 88), which help to create a resistance to a particular infectious disease and helps to stop the spread of diseases in a community.

The most common cause of human disease is infections. Pathogens attempting to enter the body must past the body’s skin or cells, lining the body’s internal passageways. If the pathogens do succeed in entering the body, the immune system must be able to detect the virus, bacteria or parasite that has entered. The human body recognises the invader and uses a number of different strategies to destroy it. Vaccines help the body prepare for future attacks. Vaccines can contain the killed bacteria or virus, living attenuated forms of the pathogen or a toxoid. Scientists through genetic engineering can insert specific genes into DNA of certain microbes and make them into a desired antigen. The vaccine acts as an antigen, inducing the immune response

Vaccines are made of viruses or bacteria that originally cause the diseases. In order to make this viruses and bacteria usable as a vaccine, scientists choice one of the three basic methods depending on the vaccine they want to produce. The first method is using weak version of the virus causing the disease. They weaken the virus by limiting its production using chemical material. This method helps produce small amount of the virus to stimulate the immune system without harming the body. Scientists use it to make vaccines for diseases like measles, chickenpox, and mumps. (“ Weaken the Virus”1,2,3). The benefit of this method is providing a life lasting immunity for the person with one or two doses of the vaccine.( “Weaken the Virus” 9,10). However, this type of vaccine can not be used for people with low immune system .(“ Weaken the Virus” 10,11).

A vaccine works by tricking the body’s immune system into creating antibodies that fight an innocuous form of the virus. The antibodies then remain in the body, and if the person encounters the real virus, they are protected against it. The history of vaccines actually goes as far back as 200BC India or China, when it was discovered that some diseases do not infect those who have already been infected by it. This discovery led people to infect themselves with inoculated matter, thus protecting them from the disease. The first vaccine dates back to 1796 when Edward Jenner developed the smallpox vaccine using a weakend version of the cowpox disease. The concept of vaccinations through inoculation is considered by many to be one of the great science revelations of the 20th century.
