Description
Immunization through vaccination is a commonly used method of reducing the risk (increased ID50) and consequence (reduced pathogenicity) of bird or flock exposure to a disease-causing agent..Vaccination is the practice of administering live and/or killed vaccines which have been modified to minimize disease manifestation yet maximize immunity. the primary purpose of immunization is to raise the ID50 of the flock to prevent clinical disease following subsequent challenge. While some vaccines are given to protect that individual bird against disease, others are given to pass the protection on to the next generation, and others are given to prevent disease in the hen and subsequent transmission of the disease to the chickVaccines and vaccine programs vary widely in their effectiveness, and this is frequently by design. Some vaccines are designed to incite high levels of immunity to protect birds in the face of aggressive endemic disease challenges, such as vvND. These vaccines may cause a mild form of the disease themselves but are deemed appropriate and useful because of the risk associated with eventual infection of the deadly field pathogen. Vaccine selection and how they are programmed frequently becomes an exercise in risk management and cost efficiency. Local conditions must always be considered when evaluating and critiquing...
