Passive Immunotherapy

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

Vaccination is the administration of antigenic material to stimulate an individual 's immune system to develop adaptive immunity to a pathogen. In simpler words, a vaccination is the injection of a killed or weakened organism that produces immunity in the body against that organism. The immune system is the body 's defense against

(Video: 40 seconds) Vaccinations contain a dead or weakened strand of a virus that is injected into the body so that it can begin fighting the virus and make antibodies.

Active artificially acquired immunity is induced by a vaccine which is a substance that has antigens, the vaccine stimulates the primary response

When we get vaccinated our immune system activate B cells that multiple and make antibodies, other B cells become B memory cell, which make antibody whenever the microorganism we are vaccinated against infects our body. Booster shot are given because the first vaccination does not activate a significant amount of B Cells. Booster shots produce more B Cells. When more B Cells are activated more antibodies are made, which result in better protection from microorganisms we are vaccinated against (www.wedmd.com).

Live, attenuated vaccines are like the actual disease except they are weakened so that it can’t cause you to be infected. These are commonly used to combat the disease in order to make your body immune to it. Such diseases as the mumps, measles, and chickenpox. Inactivated vaccines are literally just how it sounds when the vaccine is so weakened that it will be ineffective unless you take multiple doses of the vaccine. Some of these include influenza and hepatitis A. Subunit vaccines contain antigens that can help boost your immune system. Commonly used for hepatitis B.

262). Vaccinations work by using two forms of immunity, active and passive. Active immunity occurs when the immune system is triggered by a person receiving a vaccination to produce antibodies for a specific disease process as if they have contracted the actual disease. From this point on if the person is exposed to someone infected with the disease their body will recognize it and release antibodies to fight against it. In contrast, passive immunity does not result from the person themselves receiving the vaccination but rather from antibodies a baby receives through the placenta from its mother. Passive immunity generally lasts from a few months to a year at the most which will cover children until they are able to receive their own immunizations. Children are the on the front line when it comes to spreading and preventing contagious

Vaccination is the process of creating immunity to a disease by intentionally infecting an individual with a weakened form of that disease. This triggers the immune system to develop anti-bodies that remain to fight off future attacks. Vaccines hold the same germs that cause disease, but the disease has already

In other words, it specifically triggers immune responses pertaining to the mesothelioma malignancy or targets the cancer cells at hand. Active immunotherapy excites an immune response by presenting antigens to the immune system for a response against the malignancy itself. Although the mesothelioma malignancy has a unique set of cells, the tumor does not always produce antigens. This results in the use of an antigen precursor protein called Mesothelin, which allows these antigens to form around the tumor in hopes to specifically target the malignancy site. On the other hand, passive immunotherapy does just the opposite. Passive immunotherapy does not induce an immune response; it simply and directly targets the malignancy by injecting “immune compounds that attack the cancer such as antibodies, cytokines, T cells and macrophages” (Selby). Non-specific immunotherapy injects cells that inhibit the growth of the tumor cells, preventing those cells from constant reproduction. These cells that are injected cooperate directly with the malignancy and are known as cytokines, lymphokine-activated killer cells and macrophages. Immunotherapies such as active, passive and non-specific passive all are becoming effective therapies for mesothelioma and are indicative of improving the patient’s

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

First described by Karl Landsteiner, a hapten is a small molecule that can elicit an immune response only when it attaches itself to a larger carrier molecule, usually a protein creating the hapten-carrier adduct or hapten-carrier complex. This complex then has the ability to become immunogenic. Haptens react specifically to the antibodies created against it and while the hapten, alone, cannot cause antibodies to respond it, it can bind with antibodies and act as an antigen. An example of a substance acting as a hapten is penicillin. When administered as an antibiotic, penicillin can bind with proteins in the body to form a hapten-carrier complex and cause anaphylaxis. Another example is urushiol, a toxin found in poison ivy. During exposure, urushiol can bind with skin proteins creating a complex that then can cause dermatitis.

“Immunity is the state or condition of being resistant to invading microorganisms” (Moini, 2013, p. 228). Active immunity is immunity from an immunogen and is acquired. This can result from of one or two ways; natural exposure or through vaccination. Passive immunity is slower because the body has to develop the antigens. Natural immunity is best understood by the mother automatically transferring her immunoglobulins to the fetus in utero through the umbilical cord or to the infant via breast milk. This is why breastfeeding is strongly endorsed, not just for the nutrients & vitamins that can be found in formula, but for the antibodies a baby

The first step to understanding vaccinations is realizing what they are. It should be made very clear that an immunization and a vaccination are two different things. An immunization is what occurs after a vaccination is administered. A vaccination is the specific process of administering a dead or weakened pathogen into an otherwise very healthy person. As a consumer, it is important for people to understand that there are many types of vaccines in the world, and each kind has its own unique benefits and risks. The three most common types of vaccines are live vaccines, inactivated vaccines, and subunit vaccines. A live vaccine is the one that most people associate with the topic of vaccination. A live vaccine is host to a weakened pathogen that cannot cause diseases in the person it is administered to. This weakened pathogen acts as a teacher to our body’s cells in how to react if a non-weakened pathogen were to invade our immune system. Inactivated vaccines are those in which the

Immunization or vaccination is a very effective and safe form of medicine used to prevent severe diseases occurring from viruses and other infectious organisms. It is given by drops in the mouth or injecting a person with a dead or modified disease-causing agent, in order for the person to become immune to

Whilst this is occurring, memory B cells figure out the shape of the antigen and remember it. This allows the B cells to produce antibodies much faster if the pathogen reinfects the person. The problem with the human immune system is that it takes approximately three weeks to reach peak antibody concentration and remove all of the pathogens in the body. Many pathogenic diseases (tetanus, polio, meningococcal etc) will kill the individual before the 3rd line of defence has the chance to destroy them. Vaccination involves injecting antigens (in the form of attenuated pathogens or pathogen parts) into the body. This causes the same immune response that would occur if the individual was infected with the actual disease; however, because the pathogens have been weakened (or killed) and had their reproductive ability inhibited, they cannot kill. This means that If the individual is infected by the pathogen in the future, he/she is extremely unlikely to get the disease (RNA based viruses such as Influenza are exempt from this due to their antigenic shift/drift ability). The use of repeated vaccination (eg. vaccination for a particular disease at two, four and six years of age) enhances the immune system even more.
