Standardization or tailorization of veterinary vaccines: a conscious endeavour against infectious disease of animals.

Protecting animals from infection is a major obligation of every veterinarian's work in order to preserve animal welfare while assuring human health. Highly infectious animal diseases can reduce the performances of food producing animals and may have a great economical impact on many industries. Some animal diseases can be transmitted to humans, and control of these types of diseases, is beneficial to public health. In the wild, animal populations reduced by disease can dramatically affect the ecological balance of an area. Vaccination is one part of an effective health program as it helps to prevent disease and, in most cases, is more cost-effective than treating sick animals. Veterinarians have succeeded in greatly reducing the incidence of important diseases by taking advantage from improved technologies in vaccines production and by planning vaccination schedules based on the different characteristics of available products. Today, veterinarians can recommend and plan to use vaccines designed for a specific herd or flock or class of animals and even for individual treatments.
