Translations:Advanced Field Epi:Manual 1 - Disease Control and Eradication Programs/65/en

  • Routine animal management where commercially available vaccines may be used as part of routine on-farm disease control for diseases such as clostridial diseases, leptospirosis, vibriosis, Marek’s disease, etc.
  • Prevalence reduction where specific vaccines may be used either on individual farms or at a regional level to reduce the prevalence of disease as part of a regional control or eradication program, by increasing the level of herd immunity. This can be used solely for control purposes, or as a prelude to eradication, with eradication attempts only proceeding subject to reducing prevalence of infection to an acceptable target level. For example, a key aspect of the brucellosis eradication program in Australia was the use of Strain 19 vaccine to reduce prevalence in high-prevalence regions before eradication commenced.
