Animal vaccines are medicinal products applied to prevent infectious diseases caused by many causing agents and encourage immunity against infectious diseases among the livestock. Animal vaccines control the spread of diseases, hence providing safety to animal and human health, which is vital considering the public dependence on animals. Animals serve as a significant source of food, meat, milk, protein, and other commercial goods such as leather and wool. Most frequently used veterinary vaccines include rabies vaccines, foot & mouth diseases vaccines, and equine influenza virus vaccines, which avert the spread of infectious agents by imitating the naturally acquired immunity.
