When administering vaccine to your poultry birds, sometimes vaccine quality is commonly blamed when a disease occurs to your birds, which got vaccinated; However, there are usually other factors responsible for vaccine failures in your poultry production.

5 Common Causes of Vaccine Failure in Poultry
1. High temperature
There are several factors that can make a vaccine fail. Most common is the temperature at which the vaccine is stored. Most vaccines need to be maintained in a cold, if possible refrigerated environment. High temperatures will likely reduce the vaccine’s effectiveness. If you don't have a refrigerator you should try to keep your vaccine in a cool dry place.
2. Inappropriate dosage
Sometimes vaccines fail because the wrong dosage was used to your poultry birds, or the you as a farmer did not follow the accompanying vaccine instructions. For instance, if the vaccine was meant to be put in water that birds can finish in two hours, it is dangerous to put it in water that birds will take a whole day to finish. By the end of the day, it will no longer be a vaccine, but poison.
You should always ensure all proscribed instructions are followed to minimize losses through vaccine failures.
Also, a vaccine meant to be administered such as an injection should never be put in drinking water. However, farmers sometimes change these methods for convenience.
Also, young chicks below five weeks respond less readily to vaccination than older birds. The immunity the chicks carry from their mothers may make the vaccine less effective.
3. Inappropriate time
Sometimes birds that are already infected by diseases may get vaccinated. In this case, the birds may not benefit from vaccination and in other instances, might even get worse. Thus, instead of the administered vaccines to be effective it deteriorate your birds' health such that they may not get cured.
4. Stress
Stressful conditions such as overcrowding, temperature extremes or poor feeds might also undermine the vaccine’s effectiveness.
You should always ensure your birds have freedom of movement and temperature is controlled in your poultry house. You should always key your poultry house clean and disinfect it every two weeks.
5. Human errors
Man-made errors such as the wrong method of administration, poor planning and contamination can all lead to vaccine failure.
You should make sure always a right method is used at a right time. Whenever you need any further help, you could call a local veterinary officer for assistance.
