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.

yellow fever vaccine a preparation of attenuated yellow fever virus, used to immunize against yellow fever.
a suspension of Salmonella typhi inactivated either by heat or by chemical (acetone) with an added preservative; in the U.S., the combined typhoid and paratyphoid A and B vaccines have been largely replaced by the monovalent typhoid vaccine because of the lack of evidence of effectiveness of paratyphoid A and paratyphoid B ingredients.
a bacterial vaccine prepared from an inactivated dried strain of Salmonella typhi.
indication It is prescribed for primary immunization against typhoid fever for adults and children. According to the National Institute of Health, routine typhoid vaccination is not recommended in the United States. It is only recommended for those who are traveling to areas outside of the U.S. to areas where typhoid is common.

adverse effects Among the more serious adverse effects are anaphylaxis and pain and inflammation at the site of injection.
