Immunotherapy Essay

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

It has targeted cells that work to kill and defend any pathogen or impurity that enters one’s body. In the case of cancers, a person’s cells grow abnormally forming a tumor. Unlike normal cells, cancer cells lose the ability to undergo apoptosis, cell death. Thus, one’s body harvests a tumor that most likely has a chance to spread and become deadly. Luckily, the biotech industry concocted innovative research that called for a new method of cancer treatment. Immunotherapy is designed to program one’s immune system to destroy and fight off the cancer. Originally, it has been mainly used for allergies. Dosages of medication or vaccinations are given to a patient to ensure that the immune system will not overreact to certain types of foreign substances. The therapy requires a drug that delivers an anticancer immune cell, specifically designed to attach on to the specific antigen that the tumor contains. According to scientist, immunotherapy gives patients “long term protection with reduced side effects against the cancer” (McGinley). The purpose of this treatment is to strengthen the immune system and specifically targets cancerous cells. Due to scientific research and the use of biotechnological methods, immunotherapy is able to prevent the threat of killing cells necessary to one’s body. Providing patients with a treatment that does not take a toll on their bodies, nor threaten to kill healthy cells is one relief the person

All vaccinations work in the same scientific way. When the vaccine enters the blood stream the body will react to the antigens as if it where the virus or bacteria contracted from the surrounding environment. The dose only possessing a small part of the virus, the virus will not have the opportunity to develop and express symptoms in the same

When one is given a vaccine, the body’s immune system fights the disease or virus causing the body to become immune to the disease. Before vaccines, the only way to become immune to a disease was too simply contract the disease and hopefully live with no serious side effects or passing on the potentially deadly illness or dangers in a wide-spread epidemic. Vaccinations have been saving lives for over 200 years now. Below is a chart showing the successful impact vaccinations have had in the United States.

Today, people do not really know how a vaccine works. For many illnesses, a person becomes immune once their body has fought off the infection. This is because the body can now fight the infection without suffering from

Vaccination is a process by which an individual is made immune to a particular pathogen, typically via injection. To understand vaccines, it is best to first understand how the human immune system works. In his book, Immunobiology (2001) Charles Janeway, a notable immunologist, states that there are two arms to the human immune

First, how do vaccines protect you from a specific disease? Well a vaccine is “a preparation of dead or weakened pathogens that are introduced into the body to stimulate an immune response”. Immunity is “the state of being protected against a particular disease”. So, the vaccine actually has the disease in it,

Vaccines and vaccinations are two different things. A product that produces immunity from a disease and can be administered through needle injections, by mouth, or by aerosol is called a vaccine (Basics). The injection of a killed or weakened organism that produces immunity in the body against that organism is a vaccination (Basics). A vaccine can help prevent many different and serious diseases. When you get a vaccine it will work with your body to try and protect it. When a vaccine enters your body it will create a complex system of cells and organs that evolve to fight off infectious microbes inside of your immune system (Basics). Much of the immune system’s work is carried out by a group of different specialized cells, each type designed

Vaccinations include a profound specificity to how they safeguard the well-being of the patients being given the medicine. First, the antibody cells receive stimulation with the a partial cut of the disease. Antibodies, a protein in the immune system, are responsible for the removal of the infectious disease

Vaccine provokes our bodies to produce immunity by triggering our immune system to create antibodies (a substance that fights diseases). The vaccine encourages the immune system to produce its own antibodies, which is called “active immunity” as though the person has already infectected by the disease. And once, the vaccinated person has the disease, the immune system will immediately recognize that it is time to produce antibodies. 1

When pathogens attack our body, the immune system tries to protect us since these cells can cause a disease. Your body might be weak to fight against these pathogens, thus why vaccines make a pathogen similar to a certain bacteria or virus but causes no harm to the body. Antigen-Presenting Cells travel around the body trying to find invaders. When it finds the vaccine antigen, it attacks and breaks it apart. Pathogens are covered in molecules called antigens that provoke your immune

A vaccine is a preparation of dead or weakened pathogens that reintroduced into the body to stimulate an immune response. Vaccines are administered by medical professionals, usually as an injection but sometimes as a nasal spray or oral medicine. There are many different types of vaccines which are the following live-virus vaccines, killed-virus vaccines, Toxoids, and other types.

Immunotherapy is a form of medical treatment intended to stimulate or restore the ability of the immune system to fight infection and disease. This can be by inducing, enhancing, or suppressing an immune response. Immunotherapies designed to elicit or amplify an immune response are classified as activation immunotherapies, while those that reduce or suppress immune response are suppression immunotherapies. Active immunotherapy has been effective against agents that normally cause acute self-limiting infectious disease. However, a more effective immunotherapy for chronic infectious diseases or cancer requires the use of appropriate target antigens; the

Another type of cells that protect your body is the Phagocytes. Phagocytes are types of white blood cells that directly ingest the harmful pathogens through the process of phagocytosis. They bind to the pathogen and engulf it. When it engulfs the pathogen, Phagocytes keep the antigen so it can be presented to cells to make antibodies. (Kidshealth.org)

Malignant tumors have become a major problem in public health. Chemotherapy, radiotherapy, and surgery have been the backbone of current treatment for many types of human cancer. Despite providing variably effective treatments in many cases, they are still hindered by the risk of cancer recurrence due to acquired chemo- or radio-resistance properties of some tumor cells especially tumor initiating cells [1, 2]. Recent advances in our understanding of immune system and its role in attacking tumor cells have expedited tumor control in the battle against cancer through activating immune responses [3]. Therefore, an emerging strategy in the treatment of cancers involves the stimulation of immune cells such as natural killer (NK) cells and cytotoxic T lymphocytes (CTLs) [4]. Immunotherapy is theoretically very appealing especially for tumor initiating cells, because it offers the high level of specificity.
