Avian Encephalomyelitis virus vaccine strain Calnek, substrain AE-67: 103.1 to 105.5 EID50/dose.

For active immunisation of future layers and breeding hens in order to provide passive immunity to reduce vertical transmission of avian infectious encephalomyelitis virus. It has been demonstrated that vaccinated breeding hens are able to confer passive immunity to progeny for up to 12 months post-vaccination i.e. to the end of the laying cycle.

The vaccine should be administered in the drinking water.

Birds should not be vaccinated before 10 weeks of age or later than 4 weeks before point of lay.

Discontinue use of any medications or sanitising agents being given or used in the water at least 24 hours before administering vaccine and do not resume use for 24 hours following final consumption of the vaccine-containing water.

Water used for administration of the vaccine must be non-chlorinated.

Provide enough waterers so that at least two-thirds of the birds may drink at the same time. Scrub waterers with clean non-chlorinated water. Use no disinfectant. Let waterers drain dry.

Turn off automatic waterers. The only available water should be that containing the vaccine given through ordinary waterers. Do not give through medication tanks.

To stimulate thirst, withhold all water from birds for 2 hours before vaccination.

Remove aluminium seal from vial of the vaccine. Remove rubber stopper and half-fill with cool, clean, non-chlorinated water. Replace stopper tightly and shake vial until vaccine is in solution.

Using a clean container, fill it approximately two-thirds full with cool, clean, non-chlorinated water. To this, add dried milk. Use 4 grams of skimmed milk powder if the final volume of water is to be 1 litre. Shake until skimmed milk powder is dissolved.

The skimmed milk powder must be added and dissolved first. Then add the rehydrated vaccine at the rate of 1 vial per 1,000 chickens to be vaccinated. Shake again.

Never give less than 1 dose of vaccine per bird.

Next add the mixture to the final volume of drinking water, at the rate of 1,000 doses of vaccine per 15 litres of drinking water. Never give less than 1 dose of vaccine per bird. Distribute the final volume of vaccine water evenly among the clean waterers. Do not place the waterers in direct sunlight. Resume regular water administration only after all the vaccine water has been consumed (consumption should take 1 hour).

Use clean vaccination materials.

Do not vaccinate sick, debilitated or stressed birds.

Do not vaccinate birds of less than 10 weeks of age.

In order to prevent spread of vaccine from vaccinated flocks to non-vaccinated flocks, all non-vaccinated birds present on the farm must be vaccinated at the same time.

Vaccinated animals should not be in contact with non vaccinated animals for 42 days post-vaccination.

The vaccine may induce typical signs of avian encephalomyelitis when administered orally to very young birds (less than 1 week of age).
