a process by which a person is protected against the adverse effects of infection by a disease-causing microorganism by exposing the person to a small amount of the killed or inactivated organism or to pieces of the organism.
The process of obtaining resistance to a specific disease, typically delivered through a vaccination shot or orally or nasal spray. Using killed or weakened viruses, bacterial molecules or inactivated toxins, a vaccination will introduce harmless forms of the disease into the body. Once immunized, the body then develops antibodies to fight the foreign substance.
The process of inducing immunity by administering a vaccine, thereby "teaching" the immune system to recognize certain antigen(s) and thus prevent infection or illness when it subsequently encounters the infectious agent.
This is synonymous with vaccination. A substance is introduced by injection (measles) that then stimulates an immunity response with the formation of antibodies to measles. These antibodies protect the person against getting the infection. Immunization occurs naturally during a successful pregnancy. The woman immunizes herself against her husband's HLA antigens, and she produces blocking antibodies that protect and aid in the growth of the placenta. Women with recurrent pregnancy losses fail to produce these protective antibodies because they are too similar to their husbands. Immunization (vaccination) with paternal or donor lymphocytes corrects this problem and results in subsequent live born babies when a pregnancy is established.
The process of rendering an animal protected (immune) against a certain disease. Vaccination is a way to produce immunization. However, just because an animal has been vaccinated (received a vaccine) does not necessarily mean the animal is immune. If the body did not correctly react to the vaccine or if the vaccine was defective, immunity would not occur. No vaccine produces immunity in 100% of the population to which it was given. 'Vaccination' is not the same as 'immunization.'
The process of inducing protection against a disease, usually by administering an antigen (as in a vaccine) or antibodies (as in immune globulin). (See also vaccination, but these terms are often used interchangeably.)
the process of inducing immunity by administering an antigen (vaccine) that is derived from or similar to the infecting agent, in order to allow the immune system to prevent infection or illness when it subsequently encounters the infectious agent.
the process by which a person is protected against the adverse effects of infection by a disease-causing microorganism. Active immunization (vaccination) involves inoculating a person with an antigen and relying on their body to mount an immune response. Passive immunization involves giving a patient exogenous (manufactured or transferred from another individual) antibodies.
A biological drug that stimulates the immune system to develop protective responses, usually antibodies, against a specific infectious organism or group of organisms. Vaccines are frequently made from killed or attenuated microbial organisms. Newer vaccines are sometimes made from proteins or DNA purified from microbial organisms.
The process or procedure by which a subject (person, animal, or plant) is rendered immune, or resistant to a specific disease. This term is often used interchangeably with vaccination or inoculation, although the act of inoculation does not always result in immunity.
a vaccine to protect us from disease (such as measles and chicken pox). It is important for patients having chemotherapy to avoid children who have recently had immunizations because the vaccines are sometimes made from the actual bacteria.
the process of creating immunity; vaccination with polio vaccine induces the body to produce antibodies that will protect it from future infection by poliovirus. Vaccination and inoculation are examples of immunization.
Vaccination. Immunizations work by stimulating the immune system, the natural disease-fighting system of the body. The healthy immune system is able to recognize invading bacteria and viruses and produce substances (antibodies) to destroy or disable them. Immunizations prepare the immune system to ward off a disease. To immunize against viral diseases, the virus used in the vaccine has been weakened or killed. To immunize against bacterial diseases, it is generally possible to use only a small portion of the dead bacteria to stimulate the formation of antibodies against the whole bacteria. In addition to the initial immunization process, it has been found that the effectiveness of immunizations can be improved by periodic repeat injections or "boosters." Also see Immunizations (in the plural) and Immunization of a specific type (such Immunization, Polio).
Protection against an infectious disease by vaccination, usually with a weakened (attenuated) or killed form of the disease-causing microorganism. While people are usually immunized against an infectious disease by getting vaccinated, having a disease such as measles, mumps, or rubella one time usually prevents or "immunizes" a person from getting this disease again.
Immunization, or immunisation, is the process by which an individual is exposed to an agent that is designed to fortify his or her immune system against that agent. The material is known as an immunogen. Immunization is the same as inoculation and vaccination in that inoculation and vaccination use a viable infecting agent like immunization does.
(Immunisation) A technique used to protect a portfolio against potential unfavourable variations in the value of its assets. For instance, the duration of assets is often matched with that of liabilities to protect against changes in interest rates.
In finance, interest rate immunization is a strategy that insures that a change in interest rates will not affect the value of a portfolio. Similarly, immunization can be used to insure that the value of a pension fund's or a firm's assets will increase or decrease in exactly the opposite amount of their liabilities, thus leaving the value of the pension fund's surplus or firm's equity unchanged, regardless of changes in the interest rate.
