diphtheria and tetanus toxoids and pertussis vaccine DTP vaccine: a combination of diphtheria and tetanus toxoids and pertussis vaccine; administered intramuscularly for simultaneous immunization against diphtheria, tetanus, and whooping cough. When the pertussis vaccine is an acellular form, the combination may be abbreviated DTaP.
diphtheria and tetanus toxoids and pertussis vaccine adsorbed and Haemophilus b conjugate vaccine a combination of diphtheria toxoid, tetanus toxoid, pertussis vaccine, and Haemophilus b conjugate vaccine; administered intramuscularly to children 18 months to 5 years of age for simultaneous immunization against diphtheria, tetanus, whooping cough, and infection by Haemophilus influenzae type b.
Haemophilus b conjugate vaccine (HbCV) a preparation of Haemophilus influenzae type b capsular polysaccharide covalently bound to diphtheria toxoid or to a specific diphtheria protein, meningococcal protein, or tetanus protein; it stimulates both B and T lymphocyte responses and is much more immunogenic than the polysaccharide vaccine. Administered intramuscularly as a routine immunizing agent in infants and young children.
Haemophilus b polysaccharide vaccine (HbPV) a preparation of highly purified capsular polysaccharide derived from Haemophilus influenzae type b, which stimulates an immune response in B lymphocytes only; administered intramuscularly or subcutaneously as an immunizing agent in children ages 18 months to 5 years.
hepatitis A vaccine inactivated an inactivated whole virus vaccine derived from an attenuated strain of hepatitis A virus grown in cell culture; administered intramuscularly.
hepatitis B vaccine a preparation of hepatitis B surface antigen, derived either from human plasma of carriers of hepatitis B (hepatitis B vaccine inactivated) or from cloning in yeast cells (hepatitis B vaccine [recombinant]); administered intramuscularly.
heterologous vaccine a vaccine that confers protective immunity against a pathogen that shares cross-reacting antigens with the microorganisms in the vaccine.
human diploid cell vaccine rabies vaccine prepared from rabies virus grown in cultures of human diploid embryo lung cells and inactivated; administered intramuscularly or intradermally.

measles and rubella virus vaccine live a combination of live attenuated measles and rubella viruses, administered subcutaneously for simultaneous immunization against measles and rubella.
measles virus vaccine live a live attenuated virus vaccine used for immunization against measles, although it is usually administered as the combination measles, mumps, and rubella virus vaccine.
meningococcal polysaccharide vaccine a preparation of a capsular antigen of Neisseria meningitidis, administered subcutaneously to provide immunity to meningitis.
mumps virus vaccine live a live attenuated virus vaccine used in immunization against mumps; usually administered as the combination measles, mumps, and rubella virus vaccine.
pertussis vaccine a preparation of killed Bordetella pertussis bacilli (whole-cell vaccine) or of purified antigenic components thereof (acellular vaccine), used to immunize against pertussis; generally used in combination with diphtheria and tetanus toxoids (DTP or DTaP).
plague vaccine a preparation of killed Yersinia pestis bacilli, administered intramuscularly as an active immunizing agent against plague.
pneumococcal heptavalent conjugate vaccine a preparation of capsular polysaccharides from the seven serotypes of Streptococcus pneumoniae most commonly isolated from children 6 years of age or younger, coupled to a nontoxic variant of diphtheria toxin; used as an active immunizing agent for infants and children at risk for pneumococcal disease, administered intramuscularly.
pneumococcal vaccine polyvalent a preparation of purified capsular polysaccharides from the 23 serotypes of Streptococcus pneumoniae causing the majority of pneumococcal disease; used as an active immunizing agent in persons over 2 years of age, administered intramuscularly.
poliovirus vaccine inactivated (IPV) a preparation of killed polioviruses of three types, given in a series of intramuscular or subcutaneous injections to immunize against poliomyelitis. It does not induce intestinal immunity and so is not effective for poliovirus eradication in areas where wild-type polioviruses still exist in large numbers. However, it does not cause vaccine-associated paralytic poliomyelitis and so is preferred for routine immunization in areas where the risk of infection by a wild-type poliovirus is very low, as in the United States. Called also Salk vaccine.
poliovirus vaccine live oral (OPV) an oral vaccine against poliomyelitis consisting of three types of live, attenuated polioviruses. It is given orally, often on a sugar cube, and so is convenient for administration to children and large groups of people. It induces both humoral and intestinal immunity, so is useful for immunization and poliomyelitis eradication in areas where wild-type polioviruses have not been eradicated. However, it can cause vaccine-associated paralytic poliomyelitis in persons newly vaccinated with it and their contacts, which is considered an unjustifiable risk in countries such as the United States, where the risk of exposure to wild-type polioviruses is very low. Thus, for routine immunization in the United States, it has been superseded by poliovirus vaccine inactivated. Called also Sabin vaccine.
polyvalent vaccine a vaccine prepared from cultures or antigens of more than one strain or species.
purified chick embryo cell vaccine an inactivated virus vaccine used for pre- and postexposure rabies immunization, prepared from rabies virus grown in cultures of chicken fibroblasts; administered intramuscularly.
rabies vaccine any of various vaccines against rabies consisting of inactivated virus, used for preexposure immunization to persons at high risk of exposure, such as veterinarians, and for postexposure prophylaxis in conjunction with rabies immune globulin. See human diploid cell v., purified chick embryo cell v., and rabies v. adsorbed.
rabies vaccine adsorbed (RVA) a rabies vaccine prepared from rabies virus grown in cultures of fetal rhesus monkey lung and inactivated; administered intramuscularly.
rotavirus vaccine live oral a live virus vaccine produced from a mixture of four types of rotavirus, used to immunize infants against rotaviral gastroenteritis.
rubella and mumps virus vaccine live a combination of live attenuated rubella and mumps viruses, administered subcutaneously for simultaneous immunization against rubella and mumps.
rubella virus vaccine live a live attenuated virus vaccine used for immunization against rubella, usually administered as the combination measles, mumps, and rubella virus vaccine.
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) administered subcutaneously 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.

vac·cine

(vak'sēn, vak-sēn'), Although this word is correctly stressed on the first syllable, in U.S. usage it is often stressed on the second syllable.
Originally, the live vaccine (vaccinia, cowpox) virus inoculated in the skin as prophylaxis against smallpox and obtained from the skin of calves inoculated with seed virus. Usage has extended the meaning to include essentially any preparation intended for active immunologic prophylaxis; for example, preparations of killed microbes of virulent strains or living microbes of attenuated (variant or mutant) strains; or microbial, fungal, plant, protozoal, or metazoan derivatives or products. Method of administration varies according to the vaccine, inoculation being the most common, but ingestion is preferred in some instances and nasal spray is used occasionally.

vaccine

A suspension of microorganisms of one particular type that have been killed or modified so as to be safe, given to promote the production of specific ANTIBODIES to the organism for purposes of future protection against infection.
Collins Dictionary of Medicine © Robert M. Youngson 2004, 2005

vaccine

a preparation containing live, attenuated (see ATTENUATION).or inactivated (killed) microorganisms (or some part or product of them), that is used to stimulate an IMMUNE RESPONSE in the recipient, which gains IMMUNITY. The Salk polio vaccine is an example of a vaccine that contains inactivated viruses, whereas the Sabin polio vaccine is a LIVE VACCINE. The name comes from the Latin vaccinus, ‘of cows’, and relates to the work of Edward JENNER on cowpox. Vaccines are not quick-acting, but rely on the recipient to build up a supply of ANTIBODIES gradually. Compare SERUM (3). See also COMBINATION VACCINE, DNA VACCINE, SUBUNIT VACCINE.

Q. Who Should Receive the Flu Vaccine? Should I go get vaccinated for the flu? I have been told it is advised only for certain people, so who should receive this vaccine?

A. before you would like to go on with any vaccination, you should check out this very long list of links and create your own opinion:

http://www.aegis.ch/neu/links.html

at the bottom you will also find links in english. vaccinations in general are very disputable/dubious and it is probably time that we learn about it.

Q. Does the flu vaccine protect from all kinds of flu? If I get a flu vaccine does that mean I am completely protected from getting the flu?

A. No, the vaccine does not give complete protection from all the flu types out there. The vaccine protects from the most common types of flu, which are: H3N2, H1N1 and one B virus.
