Of or pertaining to a vaccine or vaccination.
The virus of vaccinia used in vaccination.
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.

Immunobiological substance used for active immunization by introducing into the body a live modified, attenuated, or killed inactivated infectious organisms or its toxin. The vaccine is capable of stimulating immune response by the host, who is thus rendered resistant to infection. The word vaccine was originally applied to the serum from a cow infected with vaccinia virus; it is now used of all immunizing agents.

medicine to prevent disease
A substance, a small amount of a dead or weakened disease-causing agent, which is administered to a person, usually by injection, which protects that person from infection by a particular microbe. If the person comes in contact with that pathogen, the body then fights it off easily and can protect against this disease in the future. This protection is called immunity.
Preparations of killed or modified microorganisms that can stimulate an immune (disease fighting) response in the body to prevent future infection with similar microorganisms. These preparations are usually delivered by needle under the skin but may be given in other ways.
A substance that contains antigenic components from an infectious organism. By stimulating an immune response (but not disease), it protects against subsequent infection by that organism, or may direct an immune response against an established infection or cancer.
a substance that contains recombinant antigen or weakened or killed infectious organisms. A vaccine provides long-term immunity against a pathogen by producing an acquired immune response giving rise to memory cells without causing disease.
an antigenic preparation used to produce active immunity to a disease to prevent or ameliorate the effects of infection with the natural or “wild” organism. Vaccines may be living, attenuated strains of viruses or bacteria which give rise to inapparent to trivial infections. Vaccines may also be killed or inactivated organisms or purified products derived from them. Formalin-inactivated toxins are used as vaccines against diphtheria and tetanus. Synthetically or genetically engineered antigens are currently being developed for use as vaccines. Some vaccines are effective by mouth, but most have to be given parenterally.

A vaccine is a non-pathogenic preparation of an antigen which following its introduction into the body stimulates the development of a protective immune response in the recipient such that he/she develops specific antibodies to the antigen introduced. This means that the individual is able to fight the pathogenic disease if and when it occurs. Vaccines are differentiated into the following categories: Live Vaccines These contain a strain of the bacterium or the virus very close to the wild strain which has lost its ability to cause disease (attenuated) but which is capable of growing in the body and in doing so it stimulates an immune response. Inactivated or Killed Vaccines These contain inactivated bacteria or viruses which are incapable of growing in the body but whose presence stimulates a protective immune response to future challenge with the live micro-organism. Some inactivated vaccines only contain fragments of the micro-organism or modified chemical substance produced by the micro-organism.
