Animal vaccination, also known as veterinary vaccination, entails immunizing domestic, livestock, or wild animals, closely intertwined with veterinary medicine. Pioneered by Louis Pasteur in 1879 with a vaccine against chicken cholera, this practice has historical significance. The concept of 'One Health' underscores the interrelation between animal and human vaccine production, as over 61% of human pathogens originate from animals. Notably, the rabies and smallpox vaccines exemplify this synergy.
Veterinary vaccines play a pivotal role in safeguarding animal and public health. They mitigate animal suffering, bolster efficient food production to support the growing human population, and substantially curtail the need for antibiotics in treating both food and companion animals
