cross-immunity

cross-immunity

a form of immunity in which immunity to one bacteria or virus is effective in protecting the animal against an antigenically similar but different organism, e.g. protection of cattle against bacillary hemoglobinuria (Clostridium haemolyticum) by vaccination against black disease (C. novyi) and measles virus vaccine used to immunize dogs against canine distemper. See also heterotypic vaccine.
