Factors to consider when planning a vaccination program for birds/poultry.

1. Age of the bird: Some vaccines are administered to a day-old chicks e.g. new cattle diseases or after a week.
2. Genetic resistance of the flock: If a flock is resistant to a certain disease naturally then vaccination may not be needed.
3. Health status of the bird: Vaccines should be administered to healthy birds not sick ones since it may not serve the purpose.
4. Feeding and management practices followed.
5. Methods of administration of the vaccine.
6. Methods of storage and available facilities.
