The process of obtaining resistance to a specific disease, typically delivered through a vaccination shot or capsule 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
Protection of susceptible individuals from communicable disease by administration of a living modified agent (as in yellow fever), a suspension of killed organism (as in whooping cough), or an inactivated toxin (as in tetanus) Temporary passive immunization can be produce by administration of antibody in the form of immune globulin in some conditions See also active immunization; passive immunization
A process for designing fixed income portfolios to obtain a target rate of return over a specified time period, within a narrow range, despite market conditions
The process by which a person or animal becomes protected against a disease; the process of inducing immunity by administering an antigen (vaccine) to allow the immune system to prevent infection or illness when it subsequently encounters the infectious agent This term is often used interchangeably with vaccination or inoculation
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
Protection of susceptible individuals from communicable diseases by administration of a living modified agent, a suspension of killed organisms, or an inactivated toxin
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
Injection with a specific antigen to promote antibody formation, to create immunity to a disease, or to make a person less susceptible to a contagious disease
A bond portfolio strategy whose goal is to eliminate the portfolio's risk, in case of a general change in the rate of interest, through the use of duration
the process of inducing immunity by administering an antigen (vaccine) to allow the immune system to prevent infection or illness when it subsequently encounters the infectious agent
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 effect whereby recipients distribute fewer copies of a chain letter if they have recently received one or more chain letters of the same motivational category CLEVO
The design of a bond portfolio to achieve a target level of return in the face of changing reinvestment rates and price levels It is the combining of short- and long-term bonds in the same portfolio to produce a predictable rate of return regardless of movements in interest rates
