to confer passive immunity to progeny for up to 12 months post-vaccination i.e. to the end
of the laying cycle.

Birds should not be vaccinated before 10 weeks of age or later than 4 weeks before start
of lay.
Use clean vaccination materials.
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 (if using 1,000 dose
presentation) or 1 vial per 2,000 chickens to be vaccinated (if using 2,000 dose
presentation). Shake again. 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).

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

Chickens:
None known.

Vaccinate healthy animals only.
In order to prevent spread of vaccine strain from vaccinated flocks to non-vaccinated
