Role of vaccination in animal health].

According to the IFAH, veterinary vaccines currently account for 26% of the global market in veterinary medicines, reflecting the importance of vaccines in animal health, as well as the number of wild and domesticated target species, and the monospecific nature of most vaccines. Multispecies vaccines include tetanus and rabies. In 2010, the number of food-producing animals was estimated to be roughly 20 billion and is rising gradually. Fowl currently represent the main food species. Veterinary vaccination has allowed the eradication of rinderpest, as officially declared last year (2011), jointly by the World Organisation for Animal Health (OIE) and the Food and Agriculture Organisation of the United Nations (FAO). Rinderpest was a real scourge, and was only the second viral disease to be totally eradicated (after human smallpox). One characteristic of veterinary vaccination is the DIVA approach, "differentiating infected from vaccinated animals". The DIVA strategy is especially interesting for regulated control of diseases like foot-and-mouth disease, infectious bovine rhinotracheitis, pseudorabies, and classical swine fever. DIVA vaccination requires prior serological testing. Vaccination is also used for wild animals such as foxes (rabies) and wild boars (classical swine fever). "In ovo" vaccination of fowl on day 18 of the incubation period is used to prevent Marek's disease for instance, and double vaccination (vector and insert) to prevent both Marek's disease and Gumboro's disease in fowl. Animal vaccination can also help to protect human health, as illustrated by fowl vaccination against salmonellosis.
