RUMINANT EMERGENCY VACCINES
Outbreaks of bacterial diseases on farms can often be successfully controlled using emergency vaccines.
An emergency vaccine is "tailor made" for each application. We will discuss the particular case with you and the likely efficacy.
Applications
  • Diseases for which there is no fully licensed vaccine.
  • Diseases induced by serotypes different to those in fully licensed vaccines. Emergency vaccines can be used alone or in conjunction with commercial vaccines.
  • Diseases occurring in age groups for which the commercial vaccine is not licensed.
  • Diseases not being controlled by licensed vaccines.
    • Examples of Applications
  • Caseous lymphadenitis (CLA) in sheep.
  • Campylobacter fetus fetus infections in cattle.
  • Salmonellosis.
  • Papilloma
    • Licensing Regulations
    The Veterinary Medicines Directorate is responsible for licensing individual emergency vaccines and the vaccine manufacturer.

    NWL Leeds has held a manufacturer's licence since 1986.

    The use of vaccines is under the control of the veterinary surgeon whose duty it is to ensure that the conditions of the licence are observed.

    Bacterial vaccines can only be made using a bacterial isolate from infected animals on a farm.

    The vaccine can generally only be used on that specific farm. Licences are generally issued for 12 months and must be renewed thereafter.
    Autogenous vaccines for individual animals
    No licence is required if a bacterium from an animal, or infected tissue, is used to produce a vaccine for the use in that individual. Wart vaccine for cattle are an important application for this technique.
