 Definition  Preparation of killed or weakened pathogens introduced into the body to produce immunity.  Why do vaccines NOT protect against all viral diseases?  Vaccination is effective only against viruses with non-varying proteins on their surfaces.  If the surface proteins mutate often the new changes are not recognized by the immune system.  Examples: Colds, Flu, and HIV
