Why is my vaccination programme not working?

[Mumo Munuve, Standard]

In poultry production systems, there are diseases that are too widespread or difficult to eradicate. These diseases or ailments require a routine vaccination program.

For long-living birds like commercial layers and improved ‘Kienyeji’ chickens, routine vaccinations are administered against Marek’s disease, Newcastle disease (NDV), Infectious bronchitis (IB), Infectious bursal disease (IBD or Gumboro), Salmonella, and fowl pox.

Other vaccinations can be added to the programme as local disease challenges dictate. These may include Coryza, Fowl cholera, and Mycoplasma. It is therefore reasonable to state that no single programme can be recommended for all regions.
