Vaccination of animals is an important part of veterinary care and health assurance. Many countries have specific requirements for the vaccination of pets and farm animals to protect both animal health and public health. This includes regular vaccinations against common diseases such as rabies, parvovirus and distemper, which can be potentially fatal to animals. Animal owners are generally obliged to have their animals vaccinated in accordance with legal requirements in order to prevent the spread of diseases and to ensure herd vaccination. Careful documentation of vaccinations is also important to provide proof of vaccination status when traveling or keeping animals.
