Vaccinations

Vaccinations help prevent disease by priming the immune system

Health planning

Vaccination strategies should be outlined in the animal health plans.

Vaccination, also known as immunisation, is a means to create immunity and prevent disease. Vaccines should be used as a part of a disease prevention programme that also addresses the environmental and management factors on the farm. Deciding on whether or not to vaccinate your animals depends on your farming system and is something that should be outlined in your Animal Health Plan.

Vaccines provide protection to some infectious diseases and are achieved by active or passive immunisation.

Active Immunisation

Active immunisation is achieved by an injection containing microbial pathogens that induce immunity but do not cause disease, or with antigenic components from pathogens . The aim of active immunisation is to provide protective immunity and create immunologic memory, then when the animal is exposed to a pathogen subsequently, it will produce a heightened immune response that prevents disease.

Passive Immunisation

Vaccination
Passive immunisation involves the transfer of preformed antibodies, such as the transfer of maternal antibodies across the placenta or though colostrum, or from one animal to another. Passive immunisation is usually used as an antitoxin to alleviate conditions or provide transient immunity (short-term protection) and is achieved by injecting a recipient animal with preformed antibodies It is usually given in the case of spider or snake bites where the preformed antibodies ameliorate the toxin from the venomous bite.

Attenuated Vaccines

These are vaccine that contains organisms that have been weakened so they lose their pathogenicity , but retain their ability to provoke an immune response. Attenuated vaccines generally require one dose as they induce long-lasting immunity.

Inactivated Vaccines

Pathogens can be inactivated by heat, chemicals or irradiation so that they are no longer able to replicate inside the host. These vaccines often require boosters to maintain immunity but are easier to produce than live-attenuated vaccines.

Purified Proteins as Vaccines

Some vaccines are made up of either monoclonal antibodies or protein molecules that have been extracted from pathogens or the exotoxins they produce, but few of these are used in farm animal health.

Several factors must be taken into account when using a vaccine, the main points of which have been highlighted below:

  • All vaccinating should be carried out by adequately trained staff
  • Always read the datasheet before administering any vaccine
  • Ensure all vaccine are stored correctly – live vaccines must be kept cool
  • Only use vaccines in date
  • Ensure correct site of administration – The data sheet will recommend the site of administrations (i.e. neck, caudal fold, ear etc. ) and this must be followed
  • Ensure the correct mode of administration – some vaccines are to be given intra-muscular, others subcutaneously, or in drinking water (poultry)
  • Record all vaccinations in the animal medicine book

Responsible Use of Medicines in Agriculture has produced a series of detailed guidelines for vaccinating farm animals, categorised by species. The full list can be found here: http://www.ruma.org.uk/vaccines/

There are vaccines available for the following cattle diseases, however emphasis should be placed on management and husbandry factors to prevent disease and not necessarily the routine use of vaccines – visit the specific pages to find out more:

OUR SUSTAINABLE LIVESTOCK PRINCIPLES:

  • Livestock should be land-based and integrated with farm cropping enterprises
  • Animals should be provided with conditions that enable them to exhibit natural behaviours
  • Dependency on veterinary medicines should be reduced without jeopardising the well-being of animals

OUR SUSTAINABLE LIVESTOCK PRACTICES:

outdoor access

Animals having outdoor access, shade, shelter, lighting and sufficient space for them to undertake free movement and to exhibit natural behaviors.

Breed

Using breeds and strains well-suited and adapted to the prevailing conditions.

Health Plan

Implementing herd and flock planning based on sound ecological practices and epidemiological knowledge.

biosecurity

Undertaking good practice with regard to biosecurity.

closed herds

Maintaining animals in closed herds and flocks and at stocking rates that enables free-movement, reduces risks of disease spread and minimises environmental damage.

forage and grazing

Forage and grazing being the main source of nutrients for ruminants, and continuously available to non-ruminants.

production practices

Avoiding the use of mutilations as standard production practices.

Antibiotics

Improved understanding and responsible usage of veterinary medicines.
