VACCINATION WHAT IS A VACCINE? Vaccines are biological products that induce an immune response particularly to a specific disease-causing agent. WHY DO WE VACCINATE POULTRY? The primary objective of vaccination is to immunize the poultry flock thus reducing the level of clinical disease and promoting optimal flock performance. In addition, vaccines are useful when protecting the bird against specific diseases.
