Most poultry vaccines are sensitive to temperature and light. A vaccine that has been stored incorrectly may look normal but give weaker protection. Careful handling on the farm helps make sure the flock gets the full benefit of each vaccination.
Follow the label first
Every vaccine comes with storage and use instructions from its manufacturer. These always take priority over general advice. Read the label and leaflet for the storage temperature, how to prepare the vaccine, how it should be given and how long it can be used after mixing.
Temperature
- Many poultry vaccines must be kept refrigerated, commonly between 2 °C and 8 °C. Check the label for the exact range.
- Do not freeze a vaccine unless the manufacturer states that it is stored frozen. Freezing can damage many vaccines.
- Use a dedicated refrigerator for vaccines and medicines, not one that is opened often for food or drinks.
- Keep a thermometer inside the refrigerator and record the temperature daily.
From delivery to the refrigerator
Check vaccines as soon as they arrive: the packaging should be intact, the cold chain should have been maintained, and the expiry date should allow time for use. Place them in the refrigerator immediately. Store vials on shelves rather than in the door, where the temperature changes each time it is opened.
Protect from light and heat
Sunlight and heat can damage vaccines quickly. Keep vaccines in their boxes until use, and carry them to the poultry house in an insulated cool box with ice packs, keeping vials from touching the ice packs directly.
Timing after preparation
Once a vaccine is reconstituted or mixed, it usually needs to be used within a limited time, as stated on the label. Prepare only as much as can be given within that time, and plan the vaccination so the work can be completed without delay.
Water vaccination
When vaccines are given through drinking water, the water itself can affect the result. Follow your veterinarian’s and the manufacturer’s advice on water quality, the removal of disinfectants such as chlorine from the water before vaccination, and whether a stabiliser should be used. Make sure all birds have enough drinker space to drink during the vaccination period.
Keep records and dispose of waste safely
Record the vaccine name, batch number, expiry date, date given, method and the flock or house vaccinated. Dispose of empty vials and unused vaccine as instructed on the label or by local rules.
