Vaccine vs. Injection — What's the Difference?

A vaccine is a biological preparation that provides active acquired immunity to a particular infectious disease. A vaccine typically contains an agent that resembles a disease-causing microorganism and is often made from weakened or killed forms of the microbe, its toxins, or one of its surface proteins.

The act of injecting.

A preparation of a weakened or killed pathogen, such as a bacterium or virus, or of a portion of the pathogen's structure, that is administered to prevent or treat infection by the pathogen and that functions by stimulating the production of an immune response.

Something that is injected, especially a dose of liquid medicine injected into the body.

A preparation from the cowpox virus that protects against smallpox when administered to an individual.

(Mathematics) A function that is one-to-one.

(Computers) A software program designed to detect and stop the progress of computer viruses.

The act of injecting, or something that is injected.

(historical)

A specimen prepared by injection.

(medicine) Of, pertaining to, caused by, or characteristic of cowpox.

(category theory) A morphism from either one of the two components of a coproduct to that coproduct.

(immunology) Of or pertaining to cowpox as a source of material for vaccination against smallpox; also, of or pertaining to such material used for vaccination.

(construction) The act of inserting materials like concrete grout or gravel by using high pressure pumps.

(archaic) Of, pertaining to, or derived from cattle.

(figuratively) The supply of additional funding to a person or a business.

(immunology)

(mathematics) A relation on sets (X,Y) that associates each element of Y with at most one element of X. Category:en:Functions

A substance given to stimulate a body's production of antibodies and provide immunity against a disease without causing the disease itself in the treatment, prepared from the agent that causes the disease (or a derivative of it; or a related, also effective, but safer disease), or a synthetic substitute; also, a dose of such a substance.

(computer security) The insertion of program code into an application, URL, hardware, etc.; especially when malicious or when the target is not designed for such insertion.

The process of vaccination; immunization, inoculation.

(space) The act of putting a spacecraft into a particular orbit, especially for changing a stable orbit into a transfer orbit, e.g. trans-lunar injection.

(historical) material taken from cowpox pustules used for vaccination against smallpox.

(set theory) A function that maps distinct x in the domain to distinct y in the codomain; formally, a f: X → Y such that f(a) = f(b) implies a = b for any a, b in the domain.

The disease cowpox, especially as a source of material for vaccination against smallpox.

(medicine) Something injected subcutaneously, intravenously, or intramuscularly by use of a syringe and a needle.

(figuratively)

(medicine) Congestion (of a body part, with blood or other fluid), such as hyperemia.

Something defensive or protective in nature, like a vaccine (sense 1.1).

(internal combustion engines) Fuel injection: the pressurized introduction of fuel into a cylinder.

(computing) A software program which protects computers against, or detects and neutralizes, computer viruses and other types of malware; an antivirus.

(steam engines) The act of throwing cold water into a condenser to produce a vacuum.

Synonym of vaccinate

(steam engines) The cold water thrown into a condenser to produce a vacuum.

Of or pertaining to cows; pertaining to, derived from, or caused by, vaccinia; as, vaccine virus; the vaccine disease.

The act of injecting or throwing in; - applied particularly to the forcible insertion of a liquid or gas, by means of a syringe, pump, etc.

Of or pertaining to a vaccine or vaccination.

That which is injected; especially, a liquid inserted thrown into a cavity of the body by a syringe or pipe; a clyster; an enema.

The virus of vaccinia used in vaccination.

The act or process of filling vessels, cavities, or tissues with a fluid or other substance.

Any preparation used to render an organism immune to some disease, by inducing or increasing the natural immunity mechanisms. Prior to 1995, such preparations usually contained killed organisms of the type for which immunity was desired, and sometimes used live organisms having attenuated virulence. Since that date, preparations containing only specific antigenic portions of the pathogenic organism have also been used. Some of these are prepared by genetic engineering techniques.

The act of throwing cold water into a condenser to produce a vacuum.

A program designed to protect a computer from software viruses, by detecting and or eliminating them.

The forceful insertion of a substance under pressure

Immunogen consisting of a suspension of weakened or dead pathogenic cells injected in order to stimulate the production of antibodies

Any solution that is injected (as into the skin)

The act of putting a liquid into the body by means of a syringe;
