information about pets and animals vaccine short form
Answers
Answer:
Vaccines have a long and successful history of preventing and controlling disease. The veterinary vaccines available today represent years of innovative research and meet many of the disease threats faced by pets and farm animals in the UK today.
Vaccines work by stimulating an immune response in an animal without causing the disease itself. When healthy animals are vaccinated, their own immune system responds to the vaccine and can remember the infectious agent to which the animal is vaccinated. This means, if appropriately vaccinated animals are then exposed to the pathogen against which they have been vaccinated, they can expect a level of protection from disease.
The main types of vaccines available can be categorised as modified-live (attenuated), inactivated and recombinant.
Modified-live (attenuated): a vaccine that contains an intact but weakened pathogen which stimulates an immune response but does not cause clinical disease.
Inactivated (killed): a vaccine that contains a completely inactivated pathogen, which is no longer infectious. These vaccines often contain an adjuvant, which is a compound added to help improve the protective immune response.
Recombinant: a vaccine that is produced using genetic engineering technology and using specific genetic material from a pathogen to produce proteins which will stimulate an immune response when the animal is vaccinated.
Toxoid: a vaccine that is based on inactivated toxins produced by pathogens. These vaccines stimulate immunity and protect the animal against these toxins.
