Sabin vaccine poliovirus v. live oral. Salk vaccine poliovirus v. inactivated. subunit vaccine a vaccine produced from specific protein subunits of a virus and thus having less risk of adverse reactions than whole virus vaccines. typhoid vaccine any of several preparations of Salmonella typhi used for immunization against typhoid fever, including a parenteral heat- and phenol-inactivated bacteria vaccine, an oral live vaccine prepared from the attenuated strain Ty21a, and a parenteral vaccine prepared from typhoid Vi capsular polysaccharide. varicella virus vaccine live a preparation of live, attenuated human herpesvirus 3 (varicella-zoster virus) used for production of immunity to varicella and herpes zoster. yellow fever vaccine a preparation of attenuated yellow fever virus, used to immunize against yellow fever.
Vaccine A preparation using a non-infectious element or relative of a particular virus or bacteria, and administered with the intention of halting the progress of an infection, or completely preventing it. vaccine (vaksēn´), agent prepared to produce active immunity that usually kills microbes, attenuated live microbes, or variant strains of microbes and can induce antibody production without producing disease. vaccine a suspension of attenuated or killed microorganisms (viruses, bacteria or rickettsiae), administered for prevention, amelioration or treatment of infectious diseases. anti-idiotype vaccine antibody made to antigenic determinants located in the variable domains of immunoglobulin molecules. Proposed as a means of regulating antibody responses and also as a substitute antigen for vaccination. vaccine-associated sarcoma see sarcoma. attenuated vaccine a vaccine prepared from live microorganisms that have lost their virulence but retained their ability to induce protective immunity. Attenuated microorganisms including particularly bacteria and viruses may be found naturally or they may be produced in the laboratory, for example by adaptation to a new medium or cell culture or they may be produced by recombinant DNA technology. autogenous vaccine a vaccine prepared from cultures of material derived from a lesion of the animal to be vaccinated, e.g. wart vaccine. bacterial vaccine a preparation of attenuated or killed bacteria, used to immunize against organisms injected, or sometimes for pyrogenetic effects in treatment of certain noninfectious diseases. biosynthetic vaccine a formulation containing a protective, noninfectious, immunogenic subunit produced in or by a biological system. caprinized vaccine a vaccine, usually a virus, attenuated by serial passage through goats, e.g. caprinized rinderpest vaccine. In highly susceptible cattle this vaccine may cause significant reactions and lapinized vaccines are preferred. core vaccine one that should always be included in the basic immunization program for the species. dead vaccine inactivated vaccine; one with organisms that have been killed. DNA vaccine DNA sequences that code for immunogenic proteins located in appropriately constructed plasmids which include strong promoters, which when injected into an animal are taken up by cells and the immunogenic proteins are expressed and elicit an immune response. No vaccines of this type are licensed and concerns about safety have not been resolved. heterotypic vaccine one developed from a virus that is antigenically distinct but related to that causing the disease for which the animal is being immunized, e.g. measles vaccine used to protect dogs from canine distemper. homotypic vaccine one developed from the same virus as that causing the disease the animal is being immunized against. human diploid cell vaccine an inactivated rabies vaccine made from rabies virus grown on human embryo lung fibroblast cells. inactivated vaccine see dead vaccine (above). killed virus (KV) vaccine see dead vaccine (above). live vaccine a vaccine prepared from live, usually attenuated, microorganisms. vaccine lymph material containing vaccinia virus collected from vaccinial vesicles of inoculated calves; used for active immunization against smallpox. mixed vaccine see mixed bacterial vaccine. modified live virus (MLV) vaccine see attenuated vaccine (above). polyvalent vaccine one prepared from more than one strain or species of microorganisms. recombinant vaccine one created by recombinant DNA technology. subunit vaccine one containing only specific antigenic proteins of the infectious agent. synthetic peptide vaccine using synthetic short peptides which correspond with major epitopes of viral proteins to elicit a protective antibody response. virus-vectored vaccine use of viruses as vectors to carry selected genes from another virus for immunization. |
