Planning a poultry vaccination schedule

Before anything else

Vaccination programmes differ by country, hatchery, disease pressure in your area and the vaccines available locally. Treat the ages below as a planning framework and confirm your final programme with a qualified veterinarian or your county or district veterinary office before you buy vaccines.

How a schedule is normally built

• Ask the hatchery in writing which vaccinations the chicks already received. Repeating them wastes money and can interfere.
• Ask your local veterinary officer which diseases are active in your area this season.
• Decide broiler or layer: a 6-week broiler needs far less than a hen that will lay for 18 months.
• Write the dates on a calendar the moment chicks arrive, not week by week.
• Record every vaccination: date, age, vaccine, batch number and who administered it.

Diseases commonly covered in East African programmes

• Marek's disease — normally given at the hatchery on day one.
• Newcastle disease — usually the backbone of the programme, with repeat doses.
• Infectious bursal disease (Gumboro) — given in the early weeks, often twice.
• Infectious bronchitis — often combined with Newcastle vaccination.
• Fowl pox and fowl typhoid — commonly included for layers and long-lived birds.
• Deworming and other routine treatments are separate from vaccination and follow their own schedule.

Vaccine handling — where most programmes fail

• Keep vaccines cold from the shop to the farm; a warm vaccine may do nothing at all.
• Use clean, chlorine-free water for drinking-water vaccination and remove water briefly beforehand so birds drink promptly.
• Vaccinate in the cool hours, early morning or evening.
• Use the whole reconstituted dose within the short window stated on the pack, then dispose of leftovers safely.
• Do not vaccinate visibly sick birds — ask your vet first.
