VACCINES USED AGAINST PARASITIC DISEASES IN VETERINARY MEDICINE

Vaccines in parasitic disease

Abstract

Parasites are living beings that cause significant health problems in humans and animals. The health problems they create cause productivity losses, deaths and consequently significant economic losses in animals. Some of the parasites are zoonotic. They are transmitted to humans as a result of ingestion of contaminated food and water, and consumption of raw or undercooked products of infected animals. The fight against parasites is generally carried out through chemical control today. However, there are disadvantages such as the development of resistance to these drugs over time due to the unconscious use of the drugs used, the accumulation of these drugs in the bodies of animals and humans, and the residue they leave in the environment. For this reason, vaccine development studies against parasites have been ongoing for many years. The aim of vaccines is to protect hosts against natural infections by stimulating the immune system against pathogens. Today, there are vaccines developed against parasites and commercially available in different countries. However, there are vaccines that have been proven effective experimentally but are not yet commercially used. This review aims to provide up-to-date information on vaccines used against parasitic diseases in veterinary medicine.
