Animal vaccination is the immunisation of a domestic, livestock or wild animal.[1] The practice is connected to veterinary medicine.[1] The first animal vaccine invented was for chicken cholera in 1879 by Louis Pasteur.[2] The production of such vaccines encounter issues in relation to the economic difficulties of individuals, the government and companies.[3] Regulation of animal vaccinations is less compared to the regulations of human vaccinations.[3][4] Vaccines are categorised into conventional and next generation vaccines.[5][6] Animal vaccines have been found to be the most cost effective and sustainable methods of controlling infectious veterinary diseases.[6] In 2017, the veterinary vaccine industry was valued at US$7 billion and it is predicted to reach US$9 billion in 2024.[7]
