Vaccines, Inactivated - ț̢
Vaccines in which the infectious microbial nucleic acid components have been destroyed by chemical or physical treatment (e.g., formalin, beta-propiolactone, gamma radiation) without affecting the antigenicity or immunogenicity of the viral coat or bacterial outer membrane proteins.
Synonyms : Inactivated Vaccines
Vaccines, Marker - ț̢
Vaccines used in conjunction with diagnostic tests to differentiate vaccinated animals from carrier animals. Marker vaccines can be either a subunit or a gene-deleted vaccine.
Synonyms :
Vaccines, Subunit - ț̢
Vaccines consisting of one or more antigens that stimulate a strong immune response. They are purified from microorganisms or produced by recombinant DNA techniques, or they can be chemically synthesized peptides.
Synonyms : Subunit Vaccines
Vaccines, Synthetic - ț̢
Small synthetic peptides that mimic surface antigens of pathogens and are immunogenic, or vaccines manufactured with the aid of recombinant DNA techniques. The latter vaccines may also be whole viruses whose nucleic acids have been modified.
