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 one of the most unknown topics for people. They inject their body with chemicals without regard to what is going into their body and how it is affecting it. I, also, am guilty of doing this. To remove my ignorance and inform others, I am going to research more on this topic. By writing this paper, I am hoping to shed more light on this unfamiliar concept.

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

All living things on this earth are subject to attack from a disease-causing agent. Therefore, multicellular animals have dedicated cells and tissues that fight off infectious microbes in order to build immunity. A multitude of specialized cells carries out much of the immune system’s work. Each of these cells is intended to fight off diseases in a particular way. Vaccination, which is one of the methods that is used to prevent germs from proliferating, is subject of many discussions. While opponents believe that most of the diseases such as diphtheria and varicella are not necessarily harmful, and that injecting questionable vaccine ingredient into a child may cause side effects, such as seizures, paralysis, proponents believe that vaccination has been one of the greatest developments of the 20th century. It has served as a protection for the community, and has saved children and parent’s time money.

Our bodies were specifically designed to fight off diseases organically through the use of our immune system. When an antigen enters our bodies, our immune system immediately acknowledges its presence and produces antibodies to fight off the foreign organism. The antibodies will search for the disease organism and will dismantle it when found. The next time the body comes in contact with

Vaccinations are produced by developing a live, but weakened or inactive form of a disease. This weakened form of the disease, is then introduced into the body via injection, inhalation, or ingestion. Providing the body with this inactive version of the disease, the body’s natural defense mechanisms are triggered and begin creating antibodies against the disease, which in turn, allows

In the article, "Vaccines Prevent Infectious Diseases" by Roman Espejo from Opposing Viewpoints in Context, some background is given about vaccines. First, the article talks about some history of some diseases. "Similarly, diseases like whooping cough (pertussis), measles, mumps, and German measles (rubella) may be unfamiliar to you. In the 19th and early 20th centuries, these illnesses struck hundreds of thousands of people in the United States each year, mostly children, and tens of thousands of people died" (Espejo). This is true and is eye opening to some. Next, how a vaccine works is described. "Traditional vaccines contain either parts of microbes or whole microbes that have been killed or weakened so that they don't cause disease. When

Vaccinations/Immunization, allows for individuals to become resistant to infection, caused by a pathogen. Vaccines, either oral or injected, are prepared with a weakened or dead disease causing microorganisms /pathogens. This vaccine is given with the intensions of provoking a immune response to the disease, on a minor level. This vaccination allows for the immune response to create antibodies, and memory cells, so that if infected with a strong version of the pathogen, the body will be immune.

Vaccines are considered the number one health achievement of the twentieth century ("Achievements in Public Health”). Mass vaccinations and the herd immunity they provide are believed to have saved countless lives since their introduction. On average it takes the body a week or longer to detect, identify, and build up antibodies to unknown microbes. For some diseases a week is long enough to inflict lasting

Living in an environment where we are prone to many viruses, it’s very important that one take the proper precautions or considerations to control the risk of getting affected. However, when utilizing the ability of not becoming infected, one may question the fact weather there’s an actual effective form of prevention or not. To clarify the uncertainty, over many years one of the most strategic methods that have been used for the control and preventions of viruses are vaccinations. A vaccination takes advantage of one’s body natural ability to primarily learn how to eliminate almost any disease causing germ or microbe that affects it. Therefore vaccinations are considered one of the most effective ways to prevent severe outcomes initiated by viruses.

This learned defense system that it helps is known as the innate immune system and the adaptive immune system. The innate immune system is “a variety of protective measures which are continually functioning and provides a first-line of defense against pathogenic agents” (Clem). However, this section of our immune systems are not microbe specific, they are a generalized for all microorganisms that enter into our bodies. The innate system’s reaction includes skin, mucous membranes, normal body temperature, fever, inflammation, and a varying pH (Clem). On the other hand, the adaptive immune system is specific to pathogens, meaning the adaptive system has memory to rapidly respond to the pathogen if it invades the body a second time. The adaptive immune system includes B-cells, antibodies, and T-cells. The B-cells and antibodies are responsible for the humoral immunity which is responsible to recognize the invasion, mark the invaders, and beginning attacking. B-cells make the antibodies (Clem). The T-cells are responsible for regulating the immune responses. Vaccinations are first recognized by the innate immune system and then stimulate the adaptive immune response by introducing dead pathogens, the bacteria or virus, so that it can be ingested by white blood cells. These white blood cells stimulate the creation of antibodies to stop the invasion and mark them for “clean-up” (Clem). The function for vaccines is to introduce the immune system to the deadly diseases in a weakened form, instead of them becoming infected the normal way. Vaccines are important to help the immune system, without them the system has to learn to protect itself from dangerous pathogens by itself, leaving it vulnerable to these pathogens (Herlily,

Children are one of the most precious gifts from God that an individual can receive. Since the lives of children are so important, parents do their best to take good care of their children during their youth because they are vulnerable to many diseases due to their weak immunity. Several children suffer from sickness early in their lives, but vaccinations could stop the sicknesses from occurring. The purpose of vaccines is to give an individual immunity to a disease before it has a chance of making him or her sick. Vaccines are composed of the same germs that causes the diseases, but the germs are dead or weakened so they will not cause people to become ill. A person’s immune system reacts to a vaccine in the same

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).

For the immune system to able to keep us healthy it needs to be able to recognise what is a danger to our body and therefore needs to be removed, and what is safe. Proteins are used to do this. Pathogens have proteins on their surface called antigens, which activate the immune system. Our own cells also have surface proteins which the immune system recognises as part of the body and therefore doesn’t attack. (1)
